The GPS menu's Settings tab is where you can set the DGPS mode, enable NTRIP, set the baud rate, leap second value, and elevation mask. The GPS menu's Engineering diagnostics tab contains VBOX hardware information, GPS receiver information and is where you can perform a GPS coldstart and view/send engineering diagnostic information.
This gives the option to configure the DGPS Settings for your VBOX 3i ADAS.
Note: RTK is permanently enabled for VBOX 3i ADAS.
Tick this box if you are using an NTRIP Modem as your DGPS source. If you do not enable the NTRIP Modem here, the VBOX unit will not source RTK corrections from the connected NTRIP Modem.
RS232 baud rate
This setting lets you change the DGPS serial rate. To ensure that the VBOX receives the DGPS correction signal, you must make sure to set the correct RS232 rate.
You can change the leap second value if required. The value was increased to 18 seconds as of December 2016 - you can find more information here.
You can also change the elevation mask, with a selectable range from 5° to 25° (10° is the default). If the testing area has nearby trees or buildings, you may benefit from increasing this value to reduce the multi-path effect. You can find more information on this here.
Note: Increasing the elevation mask value will reduce the number of satellites the VBOX will be able to use.
The Information section contains information about the hardware and firmware that is connected to the software.
Click the GPS coldstart button to reset the GPS receiver, to clear the last known position and almanac.
You can read more about coldstarts here.
Send engineering code to GPS board
This area is used to set non-standard settings in the GPS engine. This should only be used on advice from a VBOX support technician.
