Retrieve Gps Data - Symmetricom SSU-2000 Technical Reference

Retrieve GPS Data

This command returns the current tracking data for the specified GPS input. If the
input specified is not a GPS Input module, the DENY response is returned.
Syntax
RTRV-DATA-GPS:[tid]:[aid]:ctag;
Parameter
[aid]
Response Format
A valid response message contains up to eight lines. Each line displays information
for one of the satellites currently being tracked. The format is:
^^^"aid:chan,sv#,snr,status"<cr lf>
...
^^^"aid:PPSSIGMA:pps_sigma"<cr lf>
^^^"aid:T3SIGMA:t3sigma_threshold"<cr lf>
where:
= module access identifier
aid
indicates the channel number used to track the corresponding
chan
= satellite vehicle number
sv#
= signal-to-noise ratio or signal strength
snr
= the current tracking status [SRC | COD | FRQ | TIM | EPH | OK]
status
where: SRC = searching, COD = code locking, FRQ = frequency locking, TIM =
setting time, EPH = retrieving Ephemeris data, OK = satellite being used in the
timing solution
pps_sigma
t3sigma_threshold
12713020-003-2 Revision F.01 – January 2007
Value
