  • Page 11: Mounting Location

    When considering where to mount the V104n, consider the following GPS reception recommendations: • Ensure there is a clear view of the sky available to the V104n so the GPS and SBAS satellites are not masked by obstructions that may reduce system performance.

  • Page 12: Vhf Interference

    Follow VHF radio manufacturers’ recommendations on how to mount their radios and what devices to keep a safe distance away. • Hand-held 5W VHF radios may not provide suitable filtering and may interfere with the V104n’s operation if too close.
  • Page 13 Chapter 2: Installation Before installing the V104n use the following diagram to ensure there are no nearby devices that may cause VHF interference. VHF Antenna 1.5 m radius at top (minimum) Use these minimum distances to determine where to place the V104n 1.0 m radius at base...

    Figure 2-5: Long sight alignment center post If you have another accurate source of heading data on your vessel, such as a gyrocompass, you may use its data to correct for a bias in V104n alignment within the V104n software configuration. Alternatively, you can physically adjust the heading of the V104n so that it renders the correct heading measurement;...

    V104n GPS Compass User Guide Flush Mount The bottom of the V104n contains two holes for flush mounting the unit to a flat surface (Figure 2-8). The flat surface may be something you fabricate per your installation, an off-the-shelf item (such as a radar mounting plate), or an existing surface on your vessel.

    Do not apply a voltage higher than 36 VDC. This will damage the receiver and void the warranty. Electrical Isolation The V104n’s power supply is isolated from the communication lines and the PC-ABS plastic enclosure isolates the electronics mechanically from the vessel (addressing the issue of vessel hull electrolysis).

    Receiver Performance The V104n works by finding four or more GPS satellites in the visible sky. It uses information from the satellites to compute a position within 3 m. Since there is some error in the GPS data calculations, the V104n also tracks a differential correction.

  • Page 30: Differential Operation

    Autonomous position capabilities of the V104n will result in position accuracies of 3 m 95% of the time. In order to improve position quality to better than 1.0 m 95%, the V104n is able to use differential corrections received through the internal SBAS demodulator.

    The secondary antenna is directly above the arrow. Supplemental Sensors The V104n has an integrated gyro and two tilt sensors. The gyro and tilt sensors are enabled by default. Both supplemental sensors are mounted on the printed circuit board inside the V104n.
  • Page 32 Figure 3-1: V104n’s tilt aiding Gyro Aiding The V104n’s internal gyro offers several benefits. It reduces the sensor volume to shorten reacquisition times when a GPS heading is lost because the satellite signals were blocked. The gyro provides a relative change in...
  • Page 33 1º per minute for up to three minutes, in times of GPS loss for either antenna. If the outage lasts longer than three minutes, the gyro will have drifted too far and the V104n begins outputting null fields in the heading output messages. There is no user control over the timeout period of the gyro.

  • Page 34: Time Constants

    V104n GPS Compass User Guide Time Constants The V104n incorporates user-configurable time constants that can provide a degree of smoothing to the heading, pitch, rate of turn (ROT), course over ground (COG), and speed measurements. You can adjust these parameters depending on the expected dynamics of the vessel.
