12-5 Saving and Recalling Traces with GSP Information Chapter 12 — GPS Receiver, Option 31
12-4 MS20xxA VNA Master UG 10580-00166 Rev. C
Almanac Complete
The system Almanac contains information about the satellites in the constellation,
ionospheric data, and special system messages. In a cold start, the GPS receiver does not have
any navigation data so the receiver does not have a current almanac. A complete system
almanac is not required to achieve a first position fix. The availability of the almanac,
however, can significantly reduce the time to first fix.
Antenna Status
OK: Antenna is connected properly and antenna is working properly
Short/Open: A short or open exists between the antenna and the connection. If this
message is displayed, then remove and replace the GPS antenna. If the message
persists, then try another Anritsu GPS antenna (part number 2000–1410). If the
message persists, then contact your nearest Anritsu Service Center.
12-5 Saving and Recalling Traces with GSP Information
Saving Traces with GPS Information
The GPS coordinates of a location can be saved along with a measurement trace. Refer to
“Save/Recall Menu” on page 3-49 for more information.
The current GPS coordinates will be saved with the measurement traces whenever GPS is on
and actively tracking satellites.
Recalling GPS Information
If the GPS coordinates were saved with a measurement trace, then when the trace is recalled,
the coordinates that were saved are recalled as well. Refer to “Save/Recall Menu” on
page 3-49 for more information about recalling a saved trace.
