Indian Space agency ISRO’s is all set to launch its sixth navigation satellite IRNSS-1F on board trusted workhorse PSLV C32 on 10th March at 4 pm.
PSLV C32 which is also expanded as Polar Satellite Launch Vehicle-C32 is going to launch the IRNSS-1F, as its 34th mission.
The ISRO has already launched five navigation satellites under Indian Regional Navigation Satellite System (IRNSS) which is aimed at providing navigation accurately on par with the US-based Global Positioning System.
These five satellites are as follows-
IRNSS-1A on 1st July, 2013
IRNSS-1B on 4th April, 2014
IRNSS-1C on 16th October, 2014
IRNSS-1D on 28th March, 2015
IRNSS-1E on 20th January, 2016.
Each Satellite costs around INR 150 Crore.
As per the ISRO Official statement, the four satellites were enough to start the functionality of IRNSS System and remaining three would make it more ‘accurate and efficient’. So the organization is planning to launch all the 7 satellites by March 2016 and put them all together to make the system operations more reliable.
“With the launch of four satellites, we were able to provide navigation for 18 hours. But after fifth launch we increased the capacity to 24 hours with an accuracy of 20 meters. The sixth IRNSS-1F and seventh launch (IRNSS-1G) will be accurate and more efficient,” an ISRO official told PTI.
Know more about IRNSS-1F Satellites
To make satellites more capable of carrying load, the scientists have used “XL” variant in previous launches. The similar ‘XL’ Configuration were also used at the time of launching Chandrayaan -1, Mars Orbiter Mission and ASTROSAT.
The satellite also carries “highly accurate rubidium atomic clock” along with its navigation and ranging payload.
Below are the important facts about IRNSS-1F, please have a look!
Name - Indian Regional Navigation Satellite System – 1F
Height – 44.4 meter
Mass – 1425 Kg.
Life – 12 year
Services - Standard Positioning Service for all users and Restricted Service, an encrypted service only for authorized users.
# The regional navigation system will provide accurate positional information to users in India and up to 1,500 km from the boundary.
How would the IRNSS-1F Launch will be done?
The satellite will be launched in Sub-Geosynchronous Transfer Orbit (sub GTO).
Its nearest point to Earth will be 284 km and the farthest, 20,657km.
As soon as the mission managers will inject the satellite into the orbit, they will deploy its solar panels.
After initiating the launch, the Master Control Facility at Hassan in Karnataka will take control of the satellite to avoid the obstacles arising at the time of launching.
