This lunch was important , as india's 1st private sector developed hall effect thruster sattelite called " poem" by Bellatrix was part of the mission payload . Hall effect thruster was 1st developed by soviet russia during cold war era in 70s . Now being used in elon musk star link and many imp space mission . The device employs electric and magnetic fields to ionise propellant gases like Xenon to make thrust.
Bellatrix first ones in the country to have designed it to operate efficiently at very low current levels .succeeded in developing the smallest Hall Thruster in the country . Bellatrix’s hall-effect thruster would offer far higher specific impulse or mileage and could double the service life of these satellites to 10 years. The thruster is expected to provide a reliable propulsion solution to the manufacturers of small satellite—a booming market which includes Elon Musk’s Starlink and Adrián Steckel’s OneWeb. It had also bagged an order from ISRO for developing the world’s first commercial Microwave Plasma Thruster, which uses water as fuel.

Slow progress.....Second-generation NaVIC navigation satellite is in orbit, with Indian-made rubidium atomic clocks!

The 2nd gen with multiple improvements has been deployed - 10 years after the first-gen was launched in 2013. Good to see continued progress in indigenous GPS alternatives.
We are slow, but I think we are moving in the right direction. The GSLV MK2 was a problematic launch vehicle in the past. The issues are ironed out, and the vehicle seems to be stable now. Also, if you see that we are pretty close to developing NGLV, we are in the process of completing the required engine. We may need another engine that can use RP1 fuel and throttle to be able to land the first stage.Slow progress.....
I am actually not very impressed by ISRO lately. This comment "Slow Progress" was to express this feeling more than anything else.The American GPS Block-1 launches started in 1978. Block-2 launches began in 1989 - 11 years later.
Approx ~10 years gap between these 'blocks/generations' is fairly industry standard. There's no point in deploying more blocks until & unless the new technologies have actually matured.
ISRO sometimes does what the PMO wants. The priority is human space missions.I am actually not very impressed by ISRO lately. This comment "Slow Progress" was to express this feeling more than anything else.
Where is ISRO going? What are they planning to do next, That will help our nation directly & in a tangible way?
I am no a big fan of " showing off Contest" i.e. Going to space, moon, Mars, etc.
These Showing of projects are for rich nations.
