Such a proud moment Guys! Whenever I get the news that ISRO is launching satellites or ISRO is going to invent this and that! Today, we the Indians are very lucky to have ISRO. You know why?
On Thursday, The Indian Space Research Organisation launched the IRNSS-11 navigation satellite from Sriharikota in Andhra Pradesh. This the eighth satellite to be a part of a constellation which is having ‘India’ on it!
ISRO officials said, “The PSLV-C41/IRNSS-1I Mission blasted off at 4.04am from the first launch pad at the Sathish Dhawan Space Centre. It was a normal lift-off.”
According to the Telegraph reports, “The space agency’s workhorse, PSLV, injected the satellite into orbit 19 minutes after lift-off from the space centre here. It was the 41st successful mission of the 43 for PSLV. The 1,425kg satellite made by Bengaluru-headquartered Alpha Design Technologies, in collaboration with ISRO, is the second satellite to be actively built by the private industry. The first, IRNSS-1H, could not be put into space because of its failure in August last year.”
ISRO Chairman K. Sivan said: “The mission as a success and congratulated scientists. IRNSS-1I was successfully placed in the designated orbit and it was a precision injection. I am confident that the NavIC constellation will serve the underprivileged and unserved for years to come. I am really grateful to the entire ISRO family for having worked this hard and making IRNSS-1I a success.”
As the Telegraph has reported, “Serving both military and civilian needs, the regional navigation satellite system, also called NavIC, will broadcast highly-accurate timing signals that a receiver can use to triangulate its location. IRNSS-1I is expected to replace IRNSS-1A, the first of the seven navigation satellites, that was rendered ineffective after its three rubidium atomic clocks failed. The seven satellites are part of the NavIC navigation satellite constellation. The launch is ISRO’s second attempt at sending a replacement satellite.
The constellation will also provide signals in a space covering India and its surroundings, which could be utilised by using receivers on the ground to determine position and time accurately. The previous mission of a PSLV carrying IRNSS-1H in August last year failed after the heat shield covering the satellite failed to separate. The IRNSS-1I mission takes place two weeks after the space agency launched GSAT-6A on board GSLV Mk-II. Though the rocket placed GSAT-6A in orbit, the ISRO lost communication with the satellite. Like its predecessors, IRNSS-1I carried two types of payloads: Navigation and Ranging.”
Meanwhile, ISRO said that “Orbiting in a temporary sub-geosynchronous oval path about 281.5 km x 20,730 km from the Earth and inclined 19.2 degrees to the Equator, it will be gradually pushed in the coming days into a geosynchronous circular orbit 36,000 km away, at an inclination of 29° over 55° East longitude.”
During post-launch address, ISRO Chairman K. Sivan claimed “The NavIC constellation is going to create history and make innovative applications to the entire community in ocean-based services, especially for the underserved and unserved. Very recently we created a NavIC-based application that will be released soon. I request industry and institutions to take these applications to the user community.”
“In a hint about the loss of the newest GSAT-6A communication satellite in March, ISRO engineers had braved setbacks and would continue to rise to new challenges. ISRO teams returned to launch activities from home ground in record 14 days after sending up GSAT-6A on March 29. The two missions used different launch pads,” he added.
