  • Page 12: Mounting Location

    This section provides information on determining the best location for the Vector Compact (n2k). GPS Reception When considering where to mount the Vector Compact (n2k), consider the following GPS reception recommendations: • Ensure there is a clear view of the sky available to the Vector Compact (n2k) so the GPS and SBAS satellites are not masked by obstructions that may reduce system performance.

  • Page 13: 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 Vector Compact (n2k)’s operation if too close.
  • Page 14 V104n GPS Compass User Guide Before installing the Vector Compact (n2k) 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...

  • Page 15: Mounting Orientation

    Chapter 2: Installation Mounting Orientation The Vector Compact (n2k) outputs heading, pitch, and roll readings regardless of the orientation of the antennas. The primary antenna is used for position.The primary and secondary antennas, working in conjunction, output heading, pitch, and roll values.

  • Page 21: Flush Mount

    Chapter 2: Installation Flush Mount The bottom of the Vector Compact (n2k) 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.
  • Page 22 Flush mounting the Vector Compact (n2k) Mark the mounting hole centers and connector center on the mounting surface. Place the Vector Compact (n2k) over the marks to ensure the planned hole centers align with the true hole centers (adjusting as necessary).

  • Page 23: Pole Mount

    Chapter 2: Installation Pole Mount Before pole mounting the Vector Compact (n2k) • Determine your mounting orientation. See “Mounting Orientation” on page 9 for more information. • Choose a location that meets the mounting location requirements. • Mark and drill the mounting holes as necessary for the threaded...
  • Page 24 Hand tighten the base to the desired orientation. Adjust the jam nut to secure the orientation. Connect the mating end of the cable to the Vector Compact (n2k) connector located on the bottom of the unit. Insert the base adapter into Vector Compact (n2k) by placing the tongue of the base into the groove of the Vector Compact (n2k) unit.
  • Page 25 V104 connector located on the bottom of the unit. Insert the base adapter into Vector Compact (n2k) by placing the tongue of the base into the groove of the Vector Compact (n2k) unit. When the tongue is properly seated in the groove, the rest of the base can be pressed into place to create a smooth seam between the base and Vector Compact (n2k) unit.

  • Page 26: Powering And Connecting To The Vector Compact (N2K)

    Powering and Connecting to the Vector Compact (n2k) Power Considerations For best performance, use clean and continuous power. The Vector Compact (n2k) power supply features reverse polarity protection but will not operate with reverse polarity. See Table B-3 on page 43 for complete power specifications.

  • Page 30: Gps Overview

    Receiver Performance The Vector Compact (n2k) 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 Vector Compact (n2k) also tracks a differential correction.

  • Page 31: Differential Operation

    (SA), atmospheric errors, timing errors, and satellite orbit errors, while enhancing system integrity. Autonomous position capabilities of the Vector Compact (n2k) 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 Vector Compact (n2k) is able to use differential corrections received through the internal SBAS demodulator.

  • Page 32: Vector Compact (N2K) Overview

    Supplemental Sensors The Vector Compact (n2k) 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 Vector Compact (n2k).
  • Page 33 Inertial sensor Inertial sensor Tilt Aiding The Vector Compact (n2k)’s accelerometers (internal tilt sensors) are factory- calibrated and enabled by default. This allows for a steady heading solution beyond the volume associated with just a fixed antenna separation. This is because the Vector Compact (n2k) knows the approximate inclination of the secondary antenna with respect to the primary antenna.
  • Page 34 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 Vector Compact (n2k) begins outputting null fields in the heading output messages. There is no user control over the timeout period of the gyro.

  • Page 35: Time Constants

    Chapter 3: Operation Time Constants The Vector Compact (n2k) 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.
