Re: Indian Space Program: News & Discussion - Sept 2016

Re: Indian ASAT Test

The two sats that Chinese built and launched for TSP are the same ones that are being used to watch over post Pulwama operations? one would expect that but could well be just an assumption. One of those sats is said to be X-band, maybe similar to Israeli origin Risat2 so, why did they target Risat1 ...

Re: Indian ASAT Test

One of the A4 tests, it is said to have reached 800km altitude, just to reinforce the message to the north west neighbor they should make the ASAT reach an electronic target at higher altitude while intersecting the orbit of one of their sat a few hours ahead of the sat passing that point over India.

With the AoA sensor as a single point of failure, what does a software patch promised by April 2019 help? turn off MCAS as well if the autopilot disengages. And I thought these critical software always go through model checking.
