Ok i've had pretty wide variation of replies.  When I see GPS drop and restore on the console it always indicates 10 satellites in view.  I'm assuming the RTCM is looking for 10.

Does anyone know how many satellites are required for a good GPS lock.  I keep losing lock which is causing me to lose the system.
