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.

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.

could be some experiment that is interfering with the signals.
