Could GPS Keep Tabs On Your Pets?
An anonymous reader writes "Google Latitude has already made headlines for allowing phone users to locate their friends, and there are countless other iPhone and Android phone apps already designed to transmit your location — but could pets be the next big thing in GPS tracking? A number of device manufacturers are marketing GPS technology as a futuristic tool for tracking your cat or dog, and even discovering exactly where they've been. These devices are sold under a number of names and brands, including Sportdog, LoCATor, RoamEO, Petcell, Zoombak and Pettrack."
My first thought was "Cool, pets don't have privacy issues so tracking them shouldn't be a problem. Would be great if they're lost". Then I thought about celebrities and their pets - how for some celebrities who think their pet is an accessory tracking their pet isn't that different to tracking them. Unfortunately its not limited to celebrities either.
Perhaps what you need is a GPS system that only switches on if the owner activates it remotely (or fails to respond to an alarm that requires you to tell it not to activate).

If you love your dog or cat, keep it on a leash outdoors. Being able to track it down when it's road kill, or frozen to death and chewed up by a snowblower, isn't being a good owner.
Just off the top of my head, my dogs and I have come across:
GPS doesn't "fix" any of this. Letting your pets wander around is no more "humane" than letting a toddler run around. Putting a cat on a leash is no less practical than putting a dog on a leash; the only difference is that, if both a cat and a dog are picked up by the pound, the cat is a lot more likely to be put down (here, half of all dogs put up for adoption find homes compared to only 10% of all cats).
Also, your neighbours aren't exactly thrilled with your cats running around, killing birds, digging up gardens and flowers, and howling at all hours of the night. Or your dogs running around chasing people.
Put a leash on it. It's cheaper than a GPS, and it can save your pets' life.
Tracking our goldfish?
Getting a little desperate in the Marketing Dept. for ideas on what to use GPS for?
Personally, I can't see the benefit for our household. The cats are either in the cat box, under a bed sleeping, or eating, or staring out a window at leaves rustle or at birds. If we had outdoor cats (unlikely seeing as how coyotes have moved into the area) it might make some sense if we had extra money laying around and we couldn't think of anything better to use it on. For most people, though, I think this a laughable idea.
Now if I were a cattle rancher, I could see maybe spending some money in order to track the cattle but I have a feeling it might be cheaper to just have the cowhands track 'em. They'd have to be around anyway to round the critters up in the event they were to go astray.
I'd guess that this will wind up getting sold in some high-end catalog. I could easily see J. R. Bigbucks buying one of these in order to brag to his friends at the country club that they know where little Fluffy is to within 3 meters.

Track the squirrels. Those little bastards are up to something.
>they're both probably going to be equally inaccurate and in the same direction
No, they will be randomly inaccurate. However, if you have lost your beloved pet, 60 ft is close enough to tell you where it is.

My left hand?
You are confusing inherently inaccurate devices with Differential GPS systems. In Differential GPS, the base station is located at a precisely known position and it constantly calculates the accuracy of the GPS measurement and broadcasts a correction signal. The location of the roving station is calculated relative to the base station using the correction signal as both know the measured location and the amount by which it is likely to be inaccurate.
This technique is used to establish highly accurate relative measurements, such as mapping a construction site. In these cases, absolute accuracy is irrelevant, the project can be feet away from where it is measured to be and no-one will care, but each building, pipe, duct will be placed to sub-centimeter accuracy relative to a known point on the site.
The correction can be applied in real time or in post-processing.

The animal pound usually do not pick up cat with a tatoo in the ear, or when they do they contact the person to which it is registered. Lately they even have programs with those chips, but I prefer a visible tatoo. What you have at the pound are most probably either stray cat, or abandoned animals, and that happen all too often with cats and dogs (neat and nice while small, and once they reach 1 year old or the next summer holiday, left over the side of the road, I wish I could have a few word with people doing that type of shit). Most people which have cat I know of, try to get their cat to come back home in the evening. So again yowling cat outside are most probably not a home cat. As for killing birds, well you realize that cats in the wild DO eat birds, rodent and various small animals, right ?

Sorry but I don't think I'm confusing things. I'm quite familiar with DGPS having used it numerous times, both automatic systems and "self built" setups where the corrections are done at a later time.
You claimed that two GPS devices "will be randomly inaccurate". I only pointed out that this is incorrect as part of the error does correlate with position (and time) so two devices in the same area at the same time will have more similar errors than devices further apart. You implied I'm somehow wrong, but I notice you didn't actually tell me how...
I have no idea if this has any relation to finding ones pet, but the point still stands.
One has to be stationary.

On the Internet
No one knows where your dog is
Or maybe they do
I'm too cheap to buy a dedicated device so when I saw that Verizon had a free demo of their Chaperone app (track your kid's cell phone etc) I was in business. I just taped my cell phone to the cat and let him out. It worked out great and I learned a lot about my cat's habits. Watching him jump when I called him was hilarious! Unfortunately the day came when I had to remove the phone, and more importantly, the tape from the cat. Trust me, you don't EVER want to try to remove duct tape from a long haired cat!
Just kidding, but I have thought about it a time or two.
