Launch of India's First Navigation Satellite Successful

An anonymous reader writes "India's first dedicated navigation satellite, the IRNSS-1A, developed by the Indian Space Research Organization, was successfully put in orbit on Monday night. The launch vehicle, PSLV-C22, bearing the 1,425-kg navigation satellite, blasted off the launch pad at the Satish Dhawan Space Center here at the scheduled lift-off time of 11.41 p.m." The satellite is the first of seven that will eventually provide a regional equivalent of GPS under complete Indian control.

    Is India's space navigation system sufficiently similar(in terms of frequencies, antenna demands, etc.) that it will be relatively easy to shoehorn into navigation chipsets along with GPS, GLONASS, and Galileo, or is it enough of an oddball in some way, either technologically or administratively(a more hardass version of the old GPS civilian precision reduction that the US used to use or occassionally threaten to use), that this is basically irrelevant for everybody who isn't Indian military?

      Well, I really fucked that up, teach me to post while sick. Anyway, my intent was to suggest that a coverage area that gets you a good chunk of southeast asia, a bit of middle east, plus the entire Indian subcontinent, some stuff to the north of it, and the Indian ocean(not exactly an abandoned bit of water, for shipping and all) seems quite likely to be worth shoving into the spec sheet if you just need to implement a few additional algorithms(that something else in your product line for the Indian market will need anyway); but without world coverage it wouldn't be worth actually increasing the BoM cost all that much.

      We do have some deep-cover operatives working in Texas(as with other authoritarian petro-theocracies, it pays to keep an eye on them); but if somebody tells you that they are "an American from Texas", they are probably telling one of the inside jokes that they use on foreigners. Texas has texans which are a totally different thing.

      We actually inherited a lot of our bureaucracy and administration from the Brits. I'm sure if you want to use the IRNSS on your cell phone, you'll just have to fill out a form to acquire a permission-form which is then submitted to a committee for speedy* evaluation.

  5. So far, it sucks. by localman57 · · Score: 4, Funny
    I am one of the early beta testers for this project. The satellite went live a few hours ago. And as far as I can tell, it's far, far inferior to the US GPS system. With GPS, I get very accurate longitude and latitude, and coarse altitude location information. All the INRSS system keeps telling me is :

    You are somewhere on the surface of a sphere 20121.2km from satellite #1

    Although they've promised a firmware upgrade that will show you as being somewhere on the circle that represents the intersection of that sphere and the Earth's surface.

      It is not three, preferably four. It is four.

      One tells you a circular line on the globe where you could be at any place on that line.
      Two tells you two intersections of that line you could be.
      Three tells you either one of the two points where you are located within a margin, or what altitude you are within a margin.
      The fourth one is to determine which of the two points you are located, your altitude, and gives significant increase in accuracy by providing overlapping spatial and temporal data.

      It may appear that three is enough as most receivers have a rudimentary altimeter based on pressure. Even in such cases, the accuracy is very poor and reasonable navigation requires computation of previous known points along with your estimated speed and direction. It is better than doing it by hand (unless you have a compass and know how to use it), but not by much.

      Even the US GPS system requires you to get a fix on at least three, and preferably four, satellites to really put you on the map (as it were).

      You need a minimum of four sats, period.

    Do you want millions of Texans telling you how to live , through federal legislation, or do you want your state's citizens to decide how you do things there in Connecticut, and we can do it our way in Texas?

    It depends. People in every state likely have the same needs and desires when it comes to things like education, healthcare, and abortion, or freedoms like who they can marry. It's silly to have to drive across a state line to address these needs or desires. If y'all want to make the steer the state animal or drive 85 on your roads, have at it. States' rights are a vestige of 18th century America, in my opinion, and today are used more for political purposes than ensuring freedom and keeping the Union viable.

    While both Connecticut and Texas are relatively rich states and contribute more to the federal treasury than they take, people in Connecticut contribute about 3x as much toward the treasury compared with Texans... Only Delaware, Minnesota, and New Jersey pay more into the treasury per capita versus what they take out. That's part of the reason the people in NJ were so upset when congress initially balked at Sandy relief.
