02 - VIPS Site Configuration Site

Identifier

There may be multiple VIPS operating within the same test ground and so to ensure the rover only uses the signals coming from the intended test site, a site identifier needs to be entered. This identifier will need to match the site identifier of the beacons that will be used.

For temporary installations, this identifier should be set to 0. For permanent installations a non-zero number should be used.

Origin

For indoor/outdoor use, it is important that the origin of the VIPS matches a global coordinate system to ensure there is a smooth transition between GNSS and VIPS position.

The enter value of the origin should be a georeferenced location that is the 0,0 point from which all VIPS beacon measurements are taken from.

Rotation Angle

As well as a georeferenced origin, it is also important that the VIPS x/y measurements are rotated correctly into a ‘North up’ frame.

The entered value in the rotation angle should be the bearing of the track direction, in degrees from North.

For indoor use only, the rotation angle should be set to 0.

Mode

Choose the Dynamics mode of the VIPS Rover, selectable between High accuracy, Auto and High dynamics.

If there are less than 10 beacons, High dynamics should be used. If there are 10 or more beacons but they are so spread out that the Rover will rarely have more than 8 Beacons in range at a time, then high dynamics should also be used. If there are 10 or more beacons in close proximity, then High accuracy should be selected.

Selecting the Auto option will pick the most appropriate mode when uploading to a Rover unit.

Output Mode

Choose the output mode of the VIPS Rover, selectable as VB3i integration (auto set when VB3i connected is chosen), Racelogic binary (default for non-VB3i modes) and 
NMEA GGA.

Output Rate

Choose the output rate of the VIPS Rover, selectable between 100 Hz, 50 Hz, 20 Hz, 10 Hz, 5 Hz and 1 Hz. When VB3i connected is selected, this is automatically fixed to 100 Hz.

Enable Kalman Filter

Not available when in VB3i connected mode.

Enable or Disable Kalman Filter output.

Indoor or Outdoor/Indoor

Choose whether the expected use will be indoors only, or outdoors and indoors.

VB3i Connected, Stand Alone, External Sync or External Time Source

• VB3i connected: For use if the VIPS Rover is connected to a VBOX 3i, a 100 Hz PPS input is received from the VBOX.
• Standalone: The VIPS Rover will generate a 100 Hz PPS output that other equipment may use for synchronisation. The time is set by the rovers internal real time clock which is set to the current UTC time by the Site Configuration Software every time a new setup is loaded.
• External sync: Allows the system to be synchronised to an external 100 Hz PPS pulse and time source.
• External time source: Lets an external device set the system clock but the VIPS system will generate the 100 Hz PPS signal.

Filter Latency

Choose the filter latency of the system, selectable between 0-15. The value is multiplied by 10, providing a range between 0-150 mS in 10 mS increments, 50 ms by default.

Rovers

You can configure multiple Rovers (up to 5) by pressing on the + icon. You can also input the serial number of the rover(s) along with the delay, selectable between -0.2-0.2 m. Press the x button to remove a Rover.

If multiple Rovers are added, the current configuration will need to be uploaded to all defined Rover units.

Channel

It is possible to change the radio frequency between 3993.6 MHz (default) and 6489.6 MHz.

Advanced

Advanced radio settings are also available, including Tx power level, Leading edge time threshold and Preamble number, however these should only be changed under the guidance of Racelogic Support.
