CALIBRATION

2.5CALIBRATION

There are two components of VanLink requiring calibration that need to be performed prior to successful operation of the VanLink operational system. The first component to be calibrated is the magnetometer. The second component to be calibrated is the antenna.

2.5.1Magnetometer Calibration

After installation, the magnetometer (part of the GPS/IMU assembly) needs to be calibrated. This procedure acquires a magnetic footprint created by any surrounding magnetically impeding structures on/in the vehicle so, regardless of the it’s orientation to magnetic north, the V750 can accurately pinpoint the current heading.

•In order to perform calibration on the IMU (magnetometer), the vehicle must be in a location free of magnetic interference and as far away as possible from any nearby structures which could potentially interfere with the magnetometer’s reference to North.

•The vehicle must be capable of driving in a tight 360 degree circle with a laptop that is connected to the GPS/IMU and running the calibration software.

2.5.2Antenna Calibration

Typically calibrated to Magnetic North (to maintain compatibility with the Troll Systems standard configuration NavTrack feature), the antenna’s orientation is calculated with an offset to the magnetometer’s current heading. This is required to accurately orient the dish to each respective receive site in reference to the vehicle’s GPS coordinates and orientation to North.

2.6REMOTE AND LOCAL CONTROL

Even without remote control, VanLink is a powerful tool. An operator can quickly press a few buttons and have the antenna accurately align itself to the desired receive site with very little training required. While the V750 is in LOCAL mode, only personnel in the vehicle have control of the V750.

Full control of the antenna, including site selection as well as most control for any additional devices, is available from the front panel. It is possible to remotely reset the V750 to enable remote control; otherwise the personnel in the vehicle must enable remote control from the front panel of the V750.
