  • Page 39: Environmental Rating

    The purpose of this test is to verify the distance traveled (Distance Made Good [DMG]) measured by the ADCP and GPS match within 1%. To do this, we use the ADCP to measure the bottom track velocity to calculate velocity of the vessel and the GPS will also measure the velocity.

  • Page 40: Test Commands

    Because it would not be possible to do a compass calibration when the ADCP is installed in the ship, it is better to feed the ADCP an alternate heading source to use, such as a DGPS or Gyro. Review the CHS command to use an alternative heading source.

  • Page 41: Gps Communication

    • Start the ADCP pinging by sending the proper commands. • Go the VT display (Located in the top right corner). • Verify ADCP data is being output. If there is no ADCP data being displayed live to the VT display, check your connections.
