Hardware Integration Guide
Introduction
b Stated band ranges satisfy requirements for both Ant1 and Ant2.
1.4.
GNSS
The AirPrime AR759x Series include optional Global Navigation Satellite System (GNSS) capabilities
via the Qualcomm gpsOne Gen8C Engine, capable of operation in assisted and stand-alone modes
using GPS, GLONASS, Beidou, Galileo, and QZSS SVs.
Note:
Galileo support pending system / satellite deployment.

Note:
All GNSS characterization data are measured in conducted RF path with GNSS simulator.
Note 1:
Open sky, all SV RF signal level = -130dBm, Number of SVs > 6
Note 2:
TTFF values show results in worst conditions (as an external host user): timing measurement start
when GPS control request is sent on AT command interface and stop when NMEA frames (1Hz
update) display 2D fix information.
