The Apollo series provides support for specialized hardware features through extended AT
commands. The features supported include the following:
GPS
The major functionality of the GPS module is to compute the correlation results between the
incoming signal and the selected PRN code based on certain Carrier Doppler Frequency, Code
Doppler Frequency, code phase, carrier phase, and the particular satellite the module is
tracking or acquiring.
