The ISRO is readying one of the two back-up navigation satellites — IRNSS-1H — to replace it in space in the second half of this year. IRNSS-1A was launched in July 2013 and has an expected lifespan of 10 years.

Noticed a large truck on the Sriharikota Road with LPSC written on its back in the first week of July. I surmise, in all likelihood, it was the 2nd stage of PSLV for the August 2017 launch.

"The satellite is ready to move from our centre to Sriharikota on August 12 on a special vehicle for integration with the rocket at the space centre," said Annadurai on the margins of a technology event.

The launch authorization board will decide on the date and time after all the checks were completed during the window for the launch schedule.

CHENNAI: India will launch a backup navigation satellite this month end as a replacement for the IRNSS-1A satellite whose three atomic clocks have failed. Reliable sources say the launch is tentatively fixed for August 31 on board PSLV-C39.

Quote
“Four satellites are enough to deliver robust navigation services. Even if IRNSS-1A is taken off the NavIC constellation, six are still operational. As per the original plan, we have two spares ready for contingency measures. So, one of them is being flown out this month,” a senior official said.
