Viewing Stable Platform Parameters

Invoke the display if your system is configured for shipboard operation with an inertial navigation unit (INU), that is, the RCP data format RCV03 with shipboard information is selected in the Setup utility.

Select Options > Stable Platform Params.

The Antenna utility display changes to show:

  • Stable Platform Parameters panel

  • On the Azimuth panel, a small yellow triangle on the outside of the compass ring denotes the ships heading.

    In the example, the triangle is at 290°.

  • On the Elevation panel:

    • The solid red arrows show the earth relative antenna positions. This is the same as if the antenna were not on a moving platform.

      All antenna scan velocity and position requests are made in earth-relative coordinates. This means that the Antenna utility for a moving platform behaves in a manner identical to the fixed platform case.

      The RCP makes the necessary corrections to the scanning.

    • The yellow outline arrows show the pedestal relative antenna positions.

      In the example, the ship is heading 290.85° and the earth relative position is 217.62. The pedestal (ship) antenna position is 283.97°.

Shipboard features on the Azimuth and Elevation panels are display-only.
