$JFREQ
This message allows the SXBlue II-L GPS to be either manually or automatically tuned to the
OmniSTAR satellite frequency. This command has the following structure:
$JFREQ,freq,symb<CR><LF>
Where “freq” is the frequency in KHz and “symb” is the symbol rate (1200 or 2400 baud).
The receiver will reply with the following response:
$>
Entering a frequency of zero with no associated symbol rate will place the OmniSTAR engine into
automatic mode. Entering a valid frequency and symbol rate will manually tune the receiver.
The following table provides frequency information for the OmniSTAR satellites. This information is
subject to change. Visit
