recommended for precise time recovery. After this is complete, it is possible to set the position mode to
manual using the coordinates provided by those services.
Note:
The receiver has a countdown timer to show the amount of time left (
position_period
) while in the
auto positioning mode. Once this timer counts to zero, the RINEX file will be generated, the receivers
position (
status gps:position:fixed
) will be true, and the [time_remaining] field will no longer be present in
the status message.

Manual Position Mode
If the location of the antenna is known, then the Manual mode should be used. This mode uses the
information provided by the datum, latitude, longitude, and altitude parameters to fix the antenna position
at startup.
NOTICE
This bypasses the auto positioning period and the 4380A will not generate a RINEX observation file. This
mode of operation is recommended ONLY if the antenna position is known. Once you set any of these
three parameters (lat, lon, or alt), the 4380A will automatically go into
manual
mode.
CAUTION
If the operator enters the manual position incorrectly, the system will indicate it is tracking satellites in the
status output, however the system may show the gps status as “not tracking” both in the status results and
on the front panel. To correct this problem ensure the position is entered correctly. If this does not work,
set the unit to the auto position mode and re-survey the antenna position.
Si l’opérateur saisit la position manuel incorrectement, le système indiquera que c’est suivi des satellites
dans la sortie de l’État, mais le système peut afficher l’état de gps comme « ne pas de suivi » dans les
résultats de l’État et sur le panneau avant. Pour correct ce problème verifier la position a été entrée
correctement. Si cela ne fonctionne pas, passez sur le mode automatique de la position et nouveau levé la
position de l’antenne.
