IRNSS Launch and Discussions

PratikDas · Post by **PratikDas** » 02 Jul 2013 08:36

Yes, Krishnan-ji, I am familiar with the fact that GAGAN is based on GPS. The end-user (civilian) doesn't care that GPS is American rather the end-user would want a cheaper phone with built in positioning (IRNSS or GPS with GAGAN). I would love to see IRNSS flourish but at least one Indian semiconductor designer has to step up and deliver a super cheap receiver. Perhaps Accord Software & Systems of Bangalore, the team behind the G3OM receiver, is best positioned to make this happen for India.

Me thinks the main users will be the military. And in applications which is driven by the government such as in agriculture etc. The free market won't adopt it over the GPS/GAGAN unless there are advantages or at least they are at par. Remember the goggle earth/maps alternative that ISRO has launched a fee years ago.

This is the second launch which I saw start to end

Congrats ISRO

If IRNSS can be commericalized, there would be huge market. Few months back there was a program in a malayalam channel about fishing in the sea. I was stunned to see the number of electronic equipments that humble boat had to locate fish. i would say a good market awaits IRNSS if properly done

Congragulations ISRO!

This is first night launch for a desi rocket I guess, most missiles tests were during daytime only

more applications,
Farm land survey coordinates
Speed monitoring on highways
Backup system for train position, have end markers as well
Wildlife conservation, IRNSS tag the elephant herds, maybe the matriarch, so somebody knows when they are near rail tracks or rampaging farms & remote villages. Rangers and UAVs can better track them and perhaps be a step ahead of the poachers
if elevation data is accurate then water level monitoring of remote lakes by deploying a IRNSS sensor on a buoy, for Himalayas if they are on verge of a cascade, people can be more informed
Enable night ops of choppers in hilly terrain

first they should find a more user friendly name than the acronym IRNSS

ok...as usual another PSLV success

Congrats
But can they please provide a better , high resolution launch video of rocket from multiple angles . High time to take care
of such a request for PSLV (please don't talk about cost and all

, only 3 - 4 extra cameras at better angle for live telecast)

yaha to rocket uda nahi ki graph dikhana shuru kar diye

My wish is to see apps that will tell a doodhwala the nearest center where there is no milk of a particular kind and charts the course for that doodhwala. Further, the doodhwala will pour the milk into the "center"., which will dole out cash (based on the fat content and the amount of milk)., the center will "package" it and the next person puts in cash and takes milk out for his family., for a good cuppa chai. The technology exists now.

OK congratulations everybody.

A home grown Excalibur type round could be the el cheepo solution for all Kargils. Pinaka and Prahaar could be the real meat cleaver solutions now. Got to stock at least 100000 rounds. Disaster and rescue management like in Uttarakhand and then the ever present danger of trains collision and wrongful stoppages not properly tracked.

The most exciting usage scenario that I could think of is as follows:

Presume Pakis having started their drama. Now imagine a non-stealth Nirbhay launched from somewhere in Rajasthan, racing towards Karachi/Gwadar with three receivers IRNSS+GLONASS+GPS. Moment and place of launch made knows to all the world powers by the simple act of not having stealthed anything from their spy sats. Now see which tracking system blinks first. Mmmaaawwwhhhhaaaa. I guess hollywood can make a movie out of it. Dicey head nodding always sweet Indians acting all unpredictable and Captain Amerika saving a trillion Pakis and facilitating the Piss process with Man Mohan Singh. All hail Capitaan Amerika.

One thing that I find strange is how the hell does PSLV work so well. Is it some alien technology seized from the office of MIB.

I don't think we need to restrict use to taxi mgmt or transportation. We could be make cheaper transceiver chip, on every device we sell in desh. Elders can wear something like a watch or necklace and be tracked, kids can be tracked, and from the data collected, we could get the data density distribution graphs, and come up with prediction models for traffic management. babooze can be tracked and checked where they are at what times, exotic animals can be tracked.. device can be standard on all vehicles, ships, and flights. one can set alert notification when certain data points collected measures to what you are looking for, e.g. send email when the bus reaches destination y. endless apps.

Today dhoti clad, chappal wearing folks put a navigation satellite into orbit.. We have come a long way from having rockets taken by bullock carts to launch pad in the 60s.

As for Rodina lovers, who could sneer at the dhoti wallahs about how high and mighty they are /were , well, here is an example of how extreme G maneuvers Rodina's launch vehicle pulled in yesterday's launch, while the Yindoos were shivering in their dhotis in the night at Sriharikota.

First the IRNSS has to be up there, while it is getting up there, sub-systems has to be designed and tested and accepted. Once the whole system is up there, reliable and the subsystems dependent upon it are tested & accepted then they will be "incorporated" into "existing wpn systems" as part of the upgrade cycle.

So lot of ways to go.

Beyond millitary applications, what are the domestic applications one can thing about?

I gave two now., doodhwala and engineer siting a mobile tower say. Both are current and tech available. What other?

Many thanks for the answer.

I hope we be able to do it within next ~5-8 years, our new cruise missiles et al and other military systems (indigenous) will start using it even faster after the desired strength of satellites is up and running.

For civilian use I can foresee our cities getting bigger surrounded with 10s and 100s of suburbs connected with massive road network.
IRNSS will help navigation of cars, taxis and buses easier. Mode of public transport becoming more organized and secure/reliable. But then the same can be done with GPS once any company take pains of developing Indian road maps and making a software. It is available even today for cars for 20 to 30K rupees cost, I think.

I use my navigator Tomtom with spoken street name/voice command and 2D map to move from one place to another without worrying about remembering the rout. It gives me shortest rout and sometimes a rout without toll

.

Taxi companies keeping an eye on their fleet, KM traveled, fuel consumption and ultimately making it safe for both passenger and driver, is another civilian use I can think for now.

Press Release from ISRO

July 02, 2013
PSLV-C22 Successfully Launches IRNSS-1A, India's First Navigation Satellite

ISRO's Polar Satellite Launch Vehicle, PSLV-C22, successfully launched IRNSS-1A, the first satellite in the Indian Regional Navigation Satellite System (IRNSS), in the early morning hours of today (July 2, 2013) from Satish Dhawan Space Centre, Sriharikota. This is the twenty third consecutively successful mission of PSLV. The 'XL' configuration of PSLV was used for the mission. Previously, the same configuration of the vehicle was used thrice to launch Chandrayaan-1, GSAT-12 and RISAT-1 satellites.

At the completion of the countdown, PSLV-C22 lifted off from the First Launch Pad at 23:41 hrs IST yesterday (July 1, 2013) with the ignition of the first stage and four strap-on motors of the launch vehicle. The important flight events, namely, stage and strap-on ignitions, heat-shield separation, stage and strap-on separations and satellite injection took place exactly as planned. After a flight of 20 minutes 17 seconds, the IRNSS-1A Satellite, weighing 1425 kg, was injected to the intended elliptical orbit of 282.46 km X 20,625.37 km.

After injection, the solar panels of IRNSS-1A were deployed automatically. ISRO's Master Control Facility (at Hassan, Karnataka) assumed the control of the satellite. In the coming days, five orbit maneuvers will be conducted from Master Control Facility to position the satellite in its Geosynchronous Circular Orbit at 55 deg East longitude.

IRNSS-1A is the first of the seven satellites constituting the space segment of the Indian Regional Navigation Satellite System. IRNSS is an independent regional navigation satellite system designed to provide position information in the Indian region and 1500 km around the Indian mainland. IRNSS would provide two types of services, namely, Standard Positioning Services (SPS) - provided to all users - and Restricted Services (RS) provided only to authorised users.

A number of ground stations responsible for the generation and transmission of navigation parameters, satellite control, satellite ranging and monitoring, etc., have been established in as many as 15 locations across the country.

The entire IRNSS constellation of seven satellites is planned to be completed by 2015-16.

Congrats to ISRO! Someone else mentioned that there could be 2 more IRNSS satellites launched this year itself. That doesn't sound realistic, perhaps one more is possible. Also, Tushar, that bottom picture is certainly the GSLV Mark 2. Is that the upcoming GSLV that will be launched in August, or is it an old file photo?

I believe i heard somewhere that ISRO will test this satellite for the next 6 months and then plan for the next launch for this series.
Probably around March time frame next year

Proton rockets are supposed to be very reliable.
This could well be the result of targeted energy weapon in space - snowden effect imo.

Hmm, the rocket boosters seemed to have failed to give the required thrust, it was wobbling as it climbed up and finally toppled. so unlikely to be an mini death star like device that would have blown it up in 1 shot.

its more like khan to introduce QC problems into space grade components sold to others.
Ariane probably runs a super-tight EU-only food chain to close the gate on that.

A sec or so after liftoff you can see either a flame or smoke of sorts, other than the plain simple blue flame. It starts to the left of the rocket and seems to move to the right. And as the rocket rotates towards the earth you can also see it rotate/spin - it is very prominent - something like 10 secs per rotation. I suspect there was a failure of one of the boosters/strap-ons.

It is rocket science., of the several variables, one going wrong can jeopardize the whole mission. Do feel proud of our missions and we should be looking forward to the day when GSLV Mk III will launch 2-3 IRNSS sats in one go.

Let us not discuss Proton-M failure. Meanwhile ISRO has good mastery over PSLV., remember the mission was delayed by some 2 weeks due to the actuator glitch.

And many more miles to go. IRNSS-1 to be commissioned and 6 more launches and commissioning to go.

Well, Apple got a free ride on the Ariane as it was the first launch on the vehicle ..in fact APPLE stands for Ariane Passenger Payload Eperiment . What my uncle and other ISRO old timers said was, that back then, they didnt have the test facilities to check the vibration and shock characteristics to qualify it for launch (the satellite should survive the shock and vibrations during ascent in the launch vehicle).

So, instead what the dhoti wallahs did was put the satellite on a bullock cart and make it go across the most rutted paths and cross country across the fields and see if it survived to qualify it!

If any of you haven't been on a bullock cart, please take a ride once across a rutted path and the ride will give you an idea..
