Mapping The Tour de France Riders From Space
Roland Piquepaille writes "It was just a matter of time before someone gets the idea of using satellite localization to map the positions of the cyclists of the Tour de France. In a first test on July 21 during the ascension to l'Alpe d'Huez, ten riders were equipped with receivers and tracked by the EGNOS European satellite positioning system, a preparatory programme for the Galileo system. The European Space Agency (ESA) reports about this first test in "The best view of the Tour is from space." It's highly possible that all riders can get receivers as soon as next year. And this data will be available on the Web, so you will know in real time the exact location of your favorite champion. Read this summary for more details and a computer-generated image showing the respective positions of Lance Armstrong and Richard Virenque, the top-ranked climber, while climbing to the top of l'Alpe d'Huez."
Bit late considering the tour's over
This story would be a whole lot better if it included a biorhythm readout of the steroid or drug content of each rider! I was listening to the CBC radio in the car again today and they had a very insightful discussion about the Belgian Christophe Brandt who withdrew after testing positive for the narcotic methadone. It seems that the Tour is being marred by this drug controversy.
However the tracking system they are planning for next year seems quite a bit better than what is currently available, like this fairly unintuitive flash gizmo on CBC.

As you may have heard, ECFA (Euthanasia for Canus Familirous Association) has purchased the GNAA (G** N***** Association of America) for an unspecified amount. Many people have had questions about the "connection" of the two associations. Thus, here's a FAQ:
Q. Why is the GNAA connecting into one ECFA?
A. Because both the GNAA and ECFA share one common goal, A HAPPIER MANKIND.
Q. Will the illicit images and homosexuality continue?
A. Unfortunately, these will not be a part of the combined ECFA, as we are moving to a broader demographic.
Q. What will the ECFA stand for?
A. Euthanasia for Canus Familirous Association.
Q. Why is the ECFA right for me?
A. Have you stepped in dog doo-doo? Do you hate dogs? Want to kill dogs? The ECFA is for you!
Q. Will the GNAA "early posts" continue?
A. Yes, these will continue, but their messages will be changed.
Q. What will the new ECFA do?
A. The ECFA would like you to do one thing - KILL A DOG. By KILLING A DOG, you will ELIMINATE one USELESSLY RESPIRATING animal from this planet. Take a stand! Help rid this INFESTATION. KILL A DOG TODAY!!!!
Q. Why do you kill dogs?
A. Are you TIRED of having your TAXES increased? Humane Societies cost our country over $100 million annually. By eliminating DOGS, this money can EDUCATE OUR KIDS. OVERPOPULATION of DOGS is RAPANT in this country. One dog can easily use the entire oxygen output of ten full size trees. One dog can output over 20 lbs of droppings daily. One dog can aggrivate the allergies of untold numbers of people with its fast growing hair and all to common dandruff. Do you own a dog? Are you tired of its mess? Don't feel like planting ten trees and waiting 10 years for them to reach maturity? Then get it euthanized. Euthanasia is a painless way for a dog to... terminate. However, it can be too expensive to buy these drugs for the LARGE NUMBER of DOGS in the HUMANE SOCIETIES. It is thus proposed that these dogs be turned into food for the homeless. One dog can feed up to five homeless children for one day.
Q. Will my favorite content still be available?
A. Yes! ECFA will be a combonation of both GNAA and ECFA. Here's the listing of content that will be used from both associations:
GNAA: troll pattern, basic format, troll network
ECFA: motto (To protect our oxygen, to clean our streets, and to curb noise pollution), message, and all your favorite existing ECFA troll messages
Q. Will I be required to change my skin color or sexual lifestyle to be a member?
A. no. People of all skin colors and sexual lifestyles are welcome. The GNAA/ECFA do not support any sexual lifestyle, skin color, or race.
Q. Where's all the content?
A. We're pulling all existing GNAA content offline on "ECF day", when we will officially connect. All your favorite ECFA content will still be available.
Q. How do I join the ECFA?
A. By simply participating in our propaganda campaign to exterminate dogs. You can become a member of our slashdot trolling team, our usenet trolling team, or you can be a member of our local campaigning - by simply handing out brocures or posting signs outside humaine socities.
Q. What is ECFA/GNAA's stance on cats?
A. We're indifferent about cats.
Q. How do I kill a dog?
A. Euthanasia is by far the most clean method, but it taints the meat and is cost prohibitive. Thus, the most economical method is our K9Zap product ($29.95), which deals a fatal shock to a dog up to 60lbs. Alternatively, the slightly messier bakers chocolate approach costs only about $0.30 per pound of dog. For more information, reply to this message or contact Gadgets for the Elimination of Dogs (GED).
NEW ECFA "early post" TROLL MESSAGE:
This "early post" is brought to you by the ECFA (Euthanasia for Canus Familirous Association). We are an organization dedicated to the eradication of dogs. ECFA (Euthanasia for Canus Familirous Association) is committed to protect our oxygen, to clean our streets, and to curb noi
They are tracked with GPS receivers. EGNOS (European Geostationary Navigation Overlay System) is the European equivalent of WAAS (Wide Area Augmentation System). These systems reduce the distortions introduced by atmospheric effects by measuring the distortions at a number of base stations with known locations and transmitting the distortion map via geostationary satellites.
On another note, Lance won again. It was actually a pretty riveting end to the Tour de France.
I wish I had known about it sooner.
Yay Lance w/ #6. While this wasn't as much of a nail biter as last years tour, the EGNOS produced a mouth watering hi-res image of armstrong's ass.
Happily yours,

Sometimes events inside the peloton go unwatched by commentators who are paying more attention to the leaders who have broken away from the main group. It would be nice to be able to see the jockeying that occurs between teams and individuals.
The data feed could also be used to help keep track of riders as they go after the green (points) jersey. This is a really exciting part of the Tour de France that never really gets as much attention as it deserves.
Let's hope this data gets put to good use. Kudos to the ESA!
Read the EFF's Fair Use FAQ
This would be a good use of APRS (automatic position reporting system). The basic idea is that you plug a gps into a handheld HAM radio, and the radio transmits your position at periodic intervals.
-jim
Hey, slashdot, how about moving a little quicker on the submissions now and then. This info would have been nifty about 3 days ago. Seeing as I just watched Lance roll through Paris I suppose we're now just early for next year.
-
I'm not trolling!
There's a stealth ingredient in his cancer drugs akin to steroids that gives him superhuman ability. No doubt about it. To wit, he never won once UNTIL he "recovered" from his bout with cancer!
I, for one, am calling for the banishment of all so-called cancer patients from sports. There are odd drug interactions going on that give them an unfair advantage.
I repeat - this isn't a troll.
An American wins your pussy race again, you worthless cheese-eating surrender monkeys. Maybe if you weren't a nation of disgusting cock gobblers, you might come up with something you can actually win yourselves. Like maybe, a contest for abject capitulationists who throw their women to the Hun as soon as der Schickelgrueber shows up for a ski weekend.
Would be nice if they used some sort of extrapolation of the original data points to make the animation more smooth. Currenlty, they just place a picture of the rider at each data point, which doesn't looke very attractive. Would be nice to see an animated picture of the pike and rider as well. But then again, this is a proof of concept for the Galileo project, and not a tool for the media.

This is a TERRORIST ATTACK waiting to happen! They will be sorry when the SCUD MISSILES are taking out riders with CENTIMETER PRESICION!
Bikes are no more affected by drugs than Baseball, Football, Soccer, track and field, swimming, you name it, there are drugs. It's only the sports that crack down on drug use that fight with the immage problem, such as the Olympics and Tour de France.

I wonder how heavy those things are, and how much it will cost them timewise in the aggregate. Imagine nearly killing yourself on small things that add up to a win or lose at the end, but always know you have this dead weight. Or are the cyclists happy about it because it is better for the fans? Do they weigh everyone's gps units to make sure they are the same? I can see people shaving off the edges of the silicon..
and should I really care?
FRWD sells gps non real time versions of this.
"These EGNOS receivers were put in the car of the team director following the cyclists" So really, they were monitoring the team cars, and not the riders. This sounds similar to the DARPA Grand Challenge, OnStar, etc.

There are issues related to possible conflicts.
Man, if Lance beat riders from space, I have even more respect for him. Those guys have, like, photon torpedos and shit on their bikes!
When all you have is a hammer, everything looks like a skull.
Mechanic: "Alright Lance, lets go through the checklist before you start the time trial."
Mechanic: "Two pound carbon fiber frame?"
Lance: "Check."
M: "180 gram tires?"
L: "Check."
M: "150 gram Titanium cogset?"
L: "Check."
M: "5 pound GPS transmitter on your helmet?"
L: "Uuuugh! Cccheeeck!" (Falls over.)
Wired had a story about Lance Armstrong's equipment and how they consider shaving 2 ounces off the weight a major improvement. Why would a rider want to carry additional deadweight, even if it is a 2 ounce GPS?
This is already done for NASCAR drivers. PitCommand uses differential GPS to track all 43 NASCAR Nextel Cup drivers every race. It also uses sensors to monitor throttle, break, and RPM.
Although it is a pay service, you can see a demo here (recent version of the Java plugin required).
Tracking race cars is more difficult than tracking bicycles due to speed. Tracking things at high speed is more difficult, because it is difficult to keep four satellites acquired. Also, race tracks have banking and grandstands, which obscures GPS signals.
When I first read the headline, I envisioned a geostat satellite taking a visual survey of the tour de france. But if you RTFA its nothing but a souped up european version of WAAS + GPS, and the trackers are not even attached to the riders bikes to boot. Kinda disappointing... but at the same time not much of a loss. Cycling isn't exactly a play by play sport. The espn highlight reels more than suffice to capture the excitement and perhaps some mayhem when someone crashes the peloton. Do you really want to see Lance climb a mountain for 2 hours.
As for drug use in the TdF, despite what many people say, the reason why drug use seems so prevalent in the TdF is because of how seriously the French race officials enforce their regulations, opposed to say major league baseball.
Nuclear war would really set back cable. - Ted Turner
...you encounter many of the same issues with cyclists. Grandstands? Tour riders enter tunnels, through mountains... oh yeah, mountains themselves, a bit taller than said grandstands... and even in the ending stage going around the Champs-Elysees they pass under a section of the road for a good 5-10 seconds that cuts off all video feed of whatever's going on under there. They've also got live heart rate monitors feeding to the producers, who can throw those stats on the screen to show how hard the sprinters are going. Even the imaging of the course itself has come a long way in the last five years - the CG terrain and elevation maps are much cooler now than they were.
Yeah, I'm being sorta defensive here... but I'd have a lot more respect for NASCAR if it depended on the fitness as well as skill of the driver rather than how well their mechanics tweaked their cars.
If they started using the helicopter cams for the sprints. They're always filming the sprints from ground-based cameras in front of the riders with ridiculous amounts of zoom. You have no chance to see who's in the lead or who's coming up fast or falling behind. Instead you have to rely on the commentator stuttering the name of whatever rider's in the lead. Hey, it's not radio, it's TV - I want to see it.
They've got the chopper hanging around all afternoon anyway, so what's the big deal?
Any sufficiently advanced libertarian utopia is indistinguishable from government.
If Armstrong comes back for another try next year, he'd have to worry about giving some of the spectators his exact coordinates. Today: spit, tomorrow: precision guided munitions.
> Man, if Lance beat riders from space, I have even more respect for him. Those guys have, like, photon torpedos and shit on their bikes!
He'll have to avoid the photards. They have photards -- the red-shirts who get stuck in the tube when trying to load... they get stuck to the enemy's field generators and cause brown-outs.
The dangers of knowledge trigger emotional distress in human beings.
Don't you know that some of the idiots in France are trying to figure out a way to ban Lance from the tour race? They despise Americans anyway, don't you know that him winning "their" race 6 times in a row has to be ticking them off. LOL
What do you mean "favorite champion"? THERE CAN ONLY BE ONE!
And why do we care?
'eom' means 'end of message, do not bother clicking.'
1. equip tour de france riders with GPS receivers
2. post to webpage for real time updates
3. Link webpage to online casino
4. Profit!!!
Ops or any of the user. 'Now that endless conflict The mobo blew worse and worse. As Confirmed that *BSD where it was when betwwen each BSD :ones in software
The proportion of xenophobic idiots, I imagine, is about the same in most countries.
Panurge has posted for the last time. Thanks for the positive moderations.
Lance is a great champ' and eveybody knows that ! ... but unfortunatly most big sportsman have ever user performance "enhancer" that is part of the game :(
Ok, there are some suspicious that whisper the "EPO" acronym
You know nothing about tour de france, and nothing about france, nothing about bicycle and nothing about one of the greatest chamion ever : Lance Amstrong. So please go and play with you tricycle kid.
... it's not about data, it's about the riders.
I don't want to see every bit of telemetry. I can't be there live, and sometimes I can't watch it on TV. (Work does tend to frown on that a bit.)
So I want to see words. I want to read a description of how the sweat is pouring off Ivan Basso as he wobbles up the last agonizing meters of Col d'Madeleine and looks over his shoulder at Virenque, a hundred meters behind. I couldn't care less whether his heart rate is 200 or his cadence is 86.5. I want to hear about Lance posing for photos and sipping champagne as he rides into Paris, not that he's doing it at 28.8 km/hr.
The folks at Velonews did a spectacular job this year describing the minute-by-minute action over every stage. I'm not going to link to it, because they'd probably have me killed if I got their server slashdotted now that it's all over, but if you care, you can find it. It's better than all the telemetry in the world.
Aren't these guys trying to shave of every microgram from their gear and bikes? Wouldn't the added weight for these 10 riders be a competitive disadvantage? Why would this consent to this? I know lance would never do it.
im a hippie
Actually it was "Germans" not French persons. That is quoting Lance, and the Race Director who saw it up close. It was lougies not spit. They were tossing stuff as well. Pretty sad. I will never purchase and T_Mobile product after hearing this as these were T-Mobile supporters. "Drunk Germans" is one quote I heard made. The French love the underdog as many of us do and of course will root for them. This is their race, in their country. They can be proud to host the biggest and best cycle race in the world. In every little town the people were out appaluding all the riders. Actually the French have a class act when it comes to le Tour de France. They were not spitting on riders. It was the damm tourists.
If you don't like what I write don't be a CS and mod it down. Refute it.
Yea I can't spell. So what is your point?

No i wasn't aware. Do you have any sources? I'd be fascinated.

"There is always some madness in love. But there is also always some reason in madness."- Friedrich Nietzsche
The other thing you have to understand is that there were hundreds of thousands of people spectating on the time trial - the commentators were saying 900,000. The crowd looked dozens deep on both sides of the road, all the way up the 16-odd kilometre (10 mile) course. The likelihood of a few drunk morons within a crowd that big is remarkably high, and given how close the spectators get to the riders it's a credit to the spectators that the riders almost always get through unmolested. Still, I have to agree with Armstrong that a time trial up that mountain wasn't a particularly good idea by the organizers - if they were going to do it, there should have been barriers the whole way up the mountain.
Be that as it may, personally I'd be just as worried about accidental interference with riders as deliberate attacks. I dunno how it actually was on the road, but there was a moment in the last stage where they were cruising (and I mean really cruising...I could have sat in the peloton at the speed they were going) through the countryside just outside Paris. Armstrong was nearly speared by an flag on a long pole. An American flag.
Any sufficiently advanced technology is indistinguishable from a rigged demo
--Andy Finkel (J. Klass?)
The article says that the receiver was mounted in the team cars for 10 select riders, not physically attached to the riders themselves. On a time trial, each rider gets a follow vehicle to help with any mechanical issues or crashes, and the follow vehicles are usually very, very close to the rider (it looks like 10 to 15 feet). So any weight would be fine, since it'll be dragged around by a gasoline motor.
...I'll state flat-out that I'm no good with maths, but I've ridden a few different wheelsets in my day, and it's pretty easy to tell the difference. It really depends on the event; aerodynamics definitely figure more than weight in a time trial, at least one where you're going fast enough for slipstream to come into play (unlike Alpe d'Huez). Those carbon disc & 5-spoke wheels are tank, relatively speaking.
The pain was excruciating and the scarring is likely permanent, but that just means it's working.
serious waste of taxpayer money.
The ones that run along side of the riders with flags are a real danger. Very crazy. Also running the ganutlet in the mountain time trials had to be a test of concentration for the top ten riders.
I was watching this AM (local time) and I didn't see that near skewering but I noticed 8 blue and yellow jerseys with AMD on the shoulders protecting Lance most of the time.
The tracking needs to be on the stupid fans that get in the race path.
The ride into Paris is not the race of the day it is the final Sprint at the end for the Green Jersey. Rarely does the Yellow Jersey attack on the last leg.
Until I saw this story, I didn't even know that there _were_ Tour de France Riders from Space. In any case, I think it's a good thing they're being mapped.
Virenque was already across the line at 5:12 PM, a full 27 or so minutes ahead of Armstrong (Richard having left the gate at 4:31 and Lance having departed at 4:59). The movie makes it look like this was positioning of the two concurrently during the race , but it is only showing a comparison of Richard's and Lance's efforts on the course. Of course, Lance dusted him!
They should call it the TOUR DE FREEDOM.
Like, those French are totally gay and everything.
USA! USA! USA!
Read my lips. We shall see whose capitalism stands in the end, the American one, the French one or the Iraqi one. Sissies.
I guess testicular cancer wasn't enough suffering to qualify Lance for 6 Tour de France championships. Two years ago Lance allowed Basso to win a stage because Basso's mother had died of cancer. And from all I've seen, Lance never fails to thank his team in interviews and often buys them gifts. Lance has his own foundation to raise money for cancer research and to help victims. It's just playa hatin'.
