1. Did you walk with your device outside the building or did you try
it from inside? You are not going to get consistent signals from
inside the building. You could try to go near the window(s).
from MIT, Chromepet to IIt gate I had perfect signal. On the flyover
opposite IIT gate, I lost the signal, but got it back at Madhya
Kailash. Again lost the signal on entering the campus. Both before
the meeting and after it, I walked around outside and tried to
acquire. For about 15-30 seconds I was able to acquire 3 satellites.
After that nothing. Again from tenet building to the exit gate, no
signal. When I left IIT and reached Raj Bhavan I got the signal back
and was getting 5-6 satellites all the way back to Chromepet.
2. Which device are you using? What is its Time To First Fix (TTFF)?
garmin 72. In Chennai, cold start takes about 2 minutes for a fix.
Warm start is about 30 seconds. Bangalore takes a little longer. In
Ooty it is less than a second.
I doubt if IIT-M has GPS jammers.
could be some experiment that is interfering with the signals.
