Isro's IRNSS-1C launch postponed for a week
The Indian Space Research Organisation (Isro) today said that the Polar Satellite Launch Vehicle (PSLV)-C26, which will carry indian Navigation Satellite (IRNSS)-1C, will be launched on October 16.
It may be noted, the launch was originally planned for October 10, but it was postponed.
The IRNSS-1C is the third of seven series of satellites to put in place India's own navigation system on par with US' Global Positioning System (GPS) from the spaceport of Sriharikota.
Isro's work-horse PSLV-C26 will lift off at 01.32 hours on October 16, from the First Launch Pad (FLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota, about 100 kms from Chennai. The vehicle will carry 1425 kgs IRNSS-1C, which is the third satellite in the series.
The statellite has already been integrated with the Vehicle and the final phase of check is progressing. The Mission Readiness Review (MRR) Committee and the Launch Authorization Board (LAB) met on October 7, 2014 to review the progress of prelaunch activities and cleared the launch for October 16, 2014, said isro. The 67-hour count down for the mission will commence at 06:32 hours on October 13, 2014.
PSLV-C26 and will use 'XL' version of PSLV and this is the seventh time the XL configuration is being flown, the last one was PSLV-C25 for the Mars Orbiter Mission.
IRNSS, is an independent regional navigation satellite system being developed by India. It is designed to provide accurate position information service to users in India as well as the region extending upto 1500 kms from its boundary, said Isro.
IRNSS-1C is the third navigation satellite, of the seven satellites constituting the IRNSS space segment. Its predecessors, IRNSS-1A and IRNSS-1B were launched by PSLV-C22 and PSLV-C24 in July 2013 and April 2014 respectively. IRNSS-1C has a lift-off mass of 1425.4 kg. The configuration of IRNSS-1C is similar to that of IRNSS-1A and IRNSS-1B.
The satellite has been realised in less than six months after the launch of its predecessor.
IRNSS-1C will carry two types of payloads - navigation payload and ranging payload. The navigation payload of IRNSS-1C will transmit navigation service signals to the users.
This payload will be operating in L5 band (1176.45 MHz) and S band (2492.028 MHz). A highly accurate Rubidium atomic clock is part of the navigation payload of the satellite. The ranging payload of IRNSSS-1C consists of a C-band transponder with facilitates accurate determination of the range of the satellite. IRNSS-1C also carries Corner Cube Retro Reflectors for laser ranging, said Isro.
IRNSS
IRNSS, is an independent regional navigation satellite system behind developed by India. It is designed to provide accurate information service to users in India as well as the region extending upto 1,500 kms from its boundary, which is the primary service area of IRNSS, which will provide two types of services including Standard Positioning Service, which is provided to all the users and Restricted Services. IRNSS comprises of a space and a ground segments.
IRNSS segment consists of seven satellites, including three satellites in geostationary orbit and four satellites in inclined geosynchronous orbit. IRNSS-1A and IRNSS-1B, the first two satellites of the IRNSS constellation, have already started functioning from their designated orbital slot after extensive on orbit test and evaluation to confirm their satisfactory performance.
IRNSS ground segment is responsible for navigation parameter generation and transmission, satellite control, ranging and integrity monitoring as well as time keeping.
The applications of IRNSS include terrestrial, aerial and marine navigation, disaster management, vehicle tracking and fleet management, integration with mobile phones, precise timing, mapping and geodetic data capture, terrestrial navigation aid for hikers and travelers and visual and voice navigation for drivers.

Re: Indian Space Programme Discussion
Not my work - the photographer's name is in the lower part of photo. But in general, like symontk mentioned, the exact timings are given out in papers. You can setup camera from a tall building and keep the finger ready on the button. The seashore launch site is barely a three or so kilometers away and the launch plume is visible.RonyKJ wrote: How did you 'catch' this? Not an easy thing to do because that rocket just takes off like a bullet.
Did you have someone near the launch pad relay the count down to you by phone while you were
ready with your camera ?
And yeah the speed! Because the photographer did not know the timing, by the time he pressed the button, I guess the rocket has nearly reached cloudlayer

The orbit is nearly twice as far compared to GPS and GLONASS.IRNSS segment consists of seven satellites, including three satellites in geostationary orbit and four satellites in inclined geosynchronous orbit. IRNSS-1A and IRNSS-1B, the first two satellites of the IRNSS constellation, have already started functioning from their designated orbital slot after extensive on orbit test and evaluation to confirm their satisfactory performance.
IRNSS ground segment is responsible for navigation parameter generation and transmission, satellite control, ranging and integrity monitoring as well as time keeping.
Comparison of Geostationary Earth Orbit with GPS, GLONASS, Galileo and Compass (medium earth orbit) satellite navigation system orbits with the International Space Station, Hubble Space Telescope and Iridium constellation orbits, and the nominal size of the Earth.[a] The Moon's orbit is around 9 times larger (in radius and length) than geostationary orbit.

Rohinis are still being launched!? What do they do with these sounding rockets, today?
Can it be used like a very highly lofted SAM?

They are used for what they are designed for - as sounding rockets to study atmospheric conditions.In fact many countries coordinate with TERLS as it is at the magnetic equator.Rohinis are still being launched!? What do they do with these sounding rockets, today?

Re: Indian Space Programme Discussion
Sounding rockets are not guided, a big difference when compared to launch vehicles or missles. By the way, the newest model of RH560 is almost as big as SLV-3ravi_g wrote: ..................

How come? SLV-3 was almost 22m long. RH560 mk2 is still less than 10 m.

French space company Arianespace is scheduled to launch an Indian earth observation satellite (EOS) on December 4. It would contain an Electronic Intelligence System (ELINT) package that will boost New Delhi's capability to collect strategic intelligence in the neighbourhood.
While the ELINT satellite launched from French Guiana will act as a force multiplier for India's National Technical Research Organisation (NTRO)

Could this be the DRDO developed surveillance satellite, that was mentioned 2-3 years ago? It is now 2 years for sure, so maybe it is ready for launch.

Re: Indian Space Programme Discussion
The sounding rockets launched in recent years seem to be all RH-200's. The last RH560 launch was officially in 1995. Does ISRO feel no need for heavier sounding rockets, since the RH-200's meet their requirements for atmospheric research?Bheeshma wrote:How come? SLV-3 was almost 22m long.

Re: Indian Space Programme Discussion
RH 560 is for ionospheric studies. I think they may have launched the RH 200 for atmospheric data prior to the IRNSS launch to get some data they needed as it is a meteorologic sounding rocket.

BANGALORE: Within a few weeks, the Indian Space Research Organisation (Isro) will team up with the Indian Air Force to conduct a simple experiment: it will drop a 3.7-tonne capsule from a height of 3.5 km and try to land it softly with parachutes. If successful, Isro will take this capsule in November-end to a height of 120 km on a rocket and eject it from there, to be recovered from the sea after a soft landing. Success in this e
