  • Page 25 TracVision G4 Technical Manual Figure 2-1 Antenna Blockage Choosing the Best Location for the TracVision Antenna There are several factors to consider when choosing the location for the TracVision antenna. • Since the TracVision antenna requires a clear view of the southern sky to receive satellite signals, the ideal antenna site has an unobstructed view of the horizon/satellite all around.
  • Page 26 19.3" 49 cm 9" (22.9 cm) 19.3" (49 cm) Radar Concerns The TracVision antenna must be kept out of line with nearby radars, as their energy levels may overload the antenna’s front- end circuits. In an ideal installation, the antenna is mounted four feet (1.2 m) above and four feet (1.2 m) away from the radar (measured from the center of the antenna dome to the center of the radar).
  • Page 27 TracVision G4 Technical Manual If uncertain of the best location for the sensor module, make a temporary installation and conduct a calibration (as described in Section 2.7, “Calibrating the Sensor” on page 40 ). Any necessary adjustments to the sensor location can be made based on the calibration scores.

  • Page 51 TracVision G4 Technical Manual Figure 2-29 Attaching the Terminal Strips to the ADCU Double-check all wiring. Be certain to plug terminal strips into the correct positions. If wiring is incomplete or incorrect or the terminal strips exchange positions, serious electrical damage can occur to the TracVision antenna unit, the GyroTrac, and interfacing electronics.
  • Page 52 Effective Strain Relief for ADCU Terminal Connections Due to both the potential number of wires that connect to the rear of the ADCU and the dynamic environment aboard ship, it is critical that the terminal connections be properly strain-relieved using tie-wraps (a number of which are included in the GyroTrac kitpack).

  • Page 53: Calibrating The Sensor

    TracVision G4 Technical Manual You must calibrate the GyroTrac sensor after installation so that it can compensate for any magnetic distortions. The ADCU is equipped with a fuse to protect against high-voltage spikes. If the system is installed correctly and power is available, but the system is non-functional, refer to Section 4.3, “GyroTrac-specific Issues”...
