SNG: Enable/Disable GLONASS Ephemeris Data
$PASHS,RAW,SNG,x,s
Enables or disables GLONASS ephemeris data on port x, where x is the output port
and s is ON or OFF.
Example: Output GLONASS ephemeris data on port A
$PASHS,RAW,SNG,A,ON<Enter>
Ephemeris data is output once every 15 minutes with one satellite output at each recording interval
(RCI).
$PASHQ,SNG,x
The associated query command is $PASHQ,SNG,x. This command outputs the SNG
ephemeris data response message on port x, where x is the optional output port.
$PASHR,SNG
The response is one binary message per locked satellite in the form:
$PASHR,SNG,(ephemeris structure)
short 2 wn week number
long 4 tow seconds of GPS week (sec) [0,...,604799]
unsigned short 2 Checksum computed by breaking the structure into shorts, adding
them together, and taking the least significant 16 bits of the
result.
