GNSS-Standalone Mode
The handset demodulates the data directly from the GNSS satellites.
This mode has some reduced cold-start sensitivity, and a longer time to first fix as compared to the assisted modes.
However, it requires no server interaction and works out of network coverage.
Default use GPS, GLONASS, BEIDOU, can use AT+CGNSSMODE set.
