1.5. GNSS Constellations
These modules are single-band GNSS receivers that can receive and track GPS, BeiDou, GLONASS,
Galileo, and QZSS signals.
1.5.1. GPS
These modules are designed to receive and track GPS L1 C/A (1574.397–1576.443 MHz) signals
provided by GPS.
1.5.2. BeiDou
They are designed to receive and track BeiDou B1I (1559.052–1563.144 MHz) signals provided by the
BeiDou Navigation Satellite System. The ability to receive and track BeiDou signals in conjunction with
GPS results in higher coverage, improved reliability, and better accuracy.
1.5.3. GLONASS
They are designed to receive and track GLONASS L1 signals (1597.781–1605.656 MHz) provided by
GLONASS.
