3. Click Submit to start logging ephemeris and almanac data.
4. Once you submitted the changes, verify that the setup was successful by
clicking on Status, and confirming that the indicator lamp for Server A-GPS
Status is green/ENABLED. The Server A-GPS Data indicator will be green if
the RINEX server is running and the GPS receiver is valid in time and PPS.
Downloading RINEX/YUMA data
Any device that can use RINEX data, can be directed to the locations where they
are stored. For example, Safran's GSG-series GNSSsimulators allow for a server
location to be set. With other equipment, you can also download the data to your
computer, and then move the files to where they are needed.
To download the data to a client computer, point your computer's web browser
to the following address:
For hourly ephemeris data:
http:// [IP address of your unit]/home/spectracom/xfer/agnss/gps/data/hourly/ [YYYY]/
[ZZZ]/hour[ZZZ]0.15n.Z
For daily ephemeris data:
http:// [IP address of your unit]/home/spectracom/xfer/agnss/gps/data/daily/ [YYYY]/
[ZZZ]/15n/spec[ZZZ]0.15n.Z
For almanac data:
http:// [IP address of your unit]/home/spectracom/xfer/agnss/gps/data/almanac/ [YYYY]/
