StellarMate Pro comes equipped with an integrated GPS/GLONASS receiver paired with an external passive antenna. It is specifically engineered for outdoor applications and may not function optimally without an unobstructed view of the sky. This receiver offers concurrent reception capability for GPS, GLONASS, Galileo, BDS, and QZSS open service L1 signals. With an impressive tally of 33 tracking channels, 99 acquisition channels, and 210 PRN channels, the SM Pro is adept at acquiring and monitoring various combinations of satellite signals.


Beyond its location services, the GPS functionality supplies highly precise timing information, which plays a pivotal role in numerous astronomical calculations executed within the device. Precise time synchronization is achieved by utilizing the GPS Pulse-Per-Second signal (PPS). The GPS PPS signal offers an extremely accurate and stable time reference.


GPS status is displayed in the StellarMate Pro App Power tab.
