Launch of India's First Navigation Satellite Successful 89

Posted by Unknown Lamer
from the satellites-for-all dept.
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?

            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.

              So the question for you in Connecticut or wherever is this:

              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 vi

                  Connecticut is one of only four states with a law specifically allowing abortion, explicitly saying your GF has the right to murder your child.
                  Texas is currently passing a law saying that more than five months into a pregancy, abortion is illegal. So the citizens of the different

      Reading TFA it is substantially different, in that the satellites are in a geostationary orbit over India. I would imagine this makes the frequencies, positioning algorithms, etc. quite different. I can understand why we did it that way, you get a working system with much fewer satellites than the GPS system

      Wish I had mod points. This is a very cogent question. Too much of what seems to be being done in space so far by prestige-oriented countries seems to simply be "follow-the-leader". Replicate the US space program (with most of its defects) as closely as possible. The Soviets even were working away on a space shuttle, though thankfully the Chinese don't seem headed down that precise dead end.

      I think the US (making a virtue out of the necessity of low budgets for space) private sector approach looks very prom

      • Apparently [wikipedia.org], the list is a decent sized one, among recent phones. My understanding is that(outside of mathematically-interesting-but-practically-useless SDR setups [sparkfun.com], which are really cool; but very computationally demanding and cost as much as most smartphones even without a host to do the compute) most GPS or GPS+others modules abstract away virtually all the dirty details and just provide position, heading, and time information(possibly some additional parameters, SNR, that sort of thing, depending on vendo

        • Actually if you want to step back a little bit from the raw signal info but not got to the other extreme you have the pseudorange, dopplar shift, carrier phase, and timing data. With that kind of data you can do useful things especially if you have a unit recording it at a well know location and communicating its data to a roving unit. With such a setup you can get accuracy on the order of a few cm instead of a few meters. Now you are in the world of RTK [wikipedia.org], differential GPS [wikipedia.org], and CORS [wikipedia.org] and can use GPS for auton
    • I would imagine in this day and age with software defined radios that you could have a "Positioning" system that would work with. Considering the number of regional systems that are available as well I would think that you could have a system that would use GPS + regional system + regional ground station systems to provide lots of accuracy and redundancy.

      Go check out the number of GPS like systems that are now up and running, it's crazy!

      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.

    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.

      One satellite and you expect miracles? Of course it can't accurately place where you are. 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).

        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.
