Building an Indian GPS module — need 2 minutes of your honest feedback

General
1

Quick background: I’m researching whether there’s a real need for an Indian-made GPS module for drones — NavIC-enabled, dual-band for professional use, and a smaller variant for FPV and hobby.

Before building anything, I want actual data, not assumptions. The survey is 8 questions, under 2 minutes, no email required.

Happy to answer questions about what I’m building in the comments. Honest criticism welcome — this is research, not a pitch.

Problem is NavIC is not fully operational and it’s satellite network is dwindling. Better to use other constellations as of now at least.

Hmm. As of today:

  • 11 NavIC satellites have been launched.
  • 8 satellites are still functional in some capacity.
  • However, only 3 satellites are currently broadcasting navigation (PNT) signals needed for positioning, navigation, and timing.
  • The other 5 functional satellites are limited to one-way messaging services and are not providing full navigation capability.

The details of these outages is interesting as it was the atomic clocks supplied by a Swiss Company that failed. There is some irony!

I don’t really thing a NavIC gps would help a lot atleast as of now.
With a decent gps and galileo beidou gps sbas you can already get around 26 sats on relatively cheap hardware. with better recievers you can probably do better

Perhaps review again when the next generation of Sats are successfully in their correct orbit. 1 for 2 so far in that regard… 2028?

And you need atleast 4 sats for geolocation.
