3.3.1 GPS:SAT:TRA:COUN?
This query returns the number of satellites being tracked.
3.3.2 GPS:SAT:VIS:COUN?
This query returns the number of satellites (PRN) that the almanac predicts should be
visible, given date, time, and position.
3.3.3 NMEA Support
The following commands allow the GPS-2700 to be used as an industry standard nav-
igation GNSS receiver. The GGA, GSV, RMC, ZDA, and PASHR NMEA commands
comprise all necessary information about the antenna position, height, velocity, direc-
tion, satellite info, fix info, time, date and other information that can be used by standard
navigation applications via the GPS-2700 RS-232 interface.
