Configuration Menu

These menus contain the set of configuration settings for GNSS Compass.

Alignment Offset

If GNSS Compass is installed into the vehicle with the positive X axis pointing forwards and the positive Z axis pointing down, then no alignment offset is required and the roll, pitch and heading offset values can remain at the factory defaults of zero.

If the unit is installed in a different orientation then the roll, pitch and heading offset must be entered. For example, if the unit is installed on its side with the X axis pointing up and the Z axis pointing forwards and no change to the Y axis, then this would result in a pitch offset of +90 degrees with roll and heading remaining zero.

If there is a small misalignment due to mechanical mounting error this can be compensated for by setting the vehicle stationary on a level surface and clicking the Zero Current Orientation button.

Note: Zero Current Orientation will only correct for roll and pitch offsets, the Heading offset must be entered manually and saved after using this function.

Reset

The Reset button causes the system to perform a power cycle. No configuration settings or state data are lost.

The Cold Start button clears all filters, and connections are reset and must re-established. No configuration settings are lost.

The Factory Reset button resets all GNSS Compass settings back to their factory defaults, including state data and all configuration settings. It also erases the hot start data so that the system is forced to perform a cold start.

Note: A Factory Reset will re-enable the DHCP Client and lose any static IP address settings.

Manual Initialisation

Ethernet Settings

The Ethernet Settings page allows you to enable or disable the DHCP Client. When the DHCP Client is disabled you need to enter the TCP/IP settings if you wish to access the web UI.

If you are only connecting to GNSS Compass via the primary port these settings can be ignored.

The default is for the Ethernet mode to be set to DHCP.

NTRIP Client

The NTRIP client built into GNSS Compass can be used to connect to a network DGPS (Differential GPS, a older standard for GNSS corrections of lower performance than RTK) or RTK service to stream correction data to GNSS Compass for DGPS or RTK. The NTRIP client requires that GNSS Compass has an available internet connection to the NTRIP Caster to function.

The source of the corrections data can be either your own base station, configured as an NTRIP Caster, or a third-party service. Either way, you will need the login details for connecting to and authenticating with the NTRIP Caster, and identifying the nearest mountpoint.

These steps are required:

1. Select Enabled.
2. For Host/Server, enter the NTRIP Caster address.
3. For Port, enter the NTRIP Caster port numbe. This is usually 2101.
4. Click Save.
5. Click Get Mountpoints.
6. Select your mountpoint from the Mountpoint drop down list, being mindful that the distance should not exceed 50km.
7. Enter your username in the Username box.
8. Enter your password in the Password box.
9. Click Save.

To disconnect from the NTRIP Caster unselect Enabled and click Save.
