To review or configure VersaSync's A-GPS settings:
- Navigate to INTERFACES: REFERENCES > GNSS Reference. The GNSS screen will be displayed.
- In the GNSS Reference panel on the right, click the GEAR button next to GNSS 0.
- In the GNSS 0 window, locate the A-GPS panel at the bottom.
- Configure the menu options as required:
Note: The options displayed on your screen depend on your system configuration.
This feature will schedule assistance data to be collected and updated every hour. On startup, if data is present, it will be sent to the receiver.
If this option is selected, VersaSync will immediately apply the time, position and satellite data to the receiver once you click Submit.
Time and position are user-configurable via the next two menu options; VersaSync collects A-GPS satellite data from an external source automatically.
Note: Once you click Submit, any parameters entered under Apply A-GPS Data will override the System time and position data. Exercise caution when using this feature, since it could negatively impact the GNSS receiver operation.
Apply VersaSync's currently used System time to the GNSS receiver.
Enter a specific date and time, instead of the System time. This may be useful if the System time is known to be incorrect, or if you need a time in the past or future e.g., for simulation purposes. Enter the date and time by using the displayed calendar and time sliders.
By accurately entering latitude, longitude (both in decimal degrees), and altitude (in meters, WGS-84) of your antenna, VersaSync can use this data during the satellite tracking/adjustment process, which typically leads to a quicker "fix". It is recommended to enter the position as accurately as possible. For more information, see Manually Setting the GNSS Position.
Note: When manually setting a position, VersaSync must be in one of the stationary modes, Standard or Single Satellite (see "Receiver Mode" above).
