GNSS constellation Details

BeiDou Receives and tracks BeiDou B1I signals at 1561.098 MHz. The ability

to receive and track BeiDou signals with another constellation,

results in higher coverage, improved reliability and better accuracy.

BeiDou coverage is only available in China, with global coverage

scheduled for 2020.

Galileo

Receives and tracks Galileo E1-B/C signals centered on the GPS L1

frequency band. GPS and Galileo signals can be processed with

either BeiDou or GLONASS signals, enhancing coverage, reliability

and accuracy.
