Configuring Radial Velocity Correction

You must input the moment arm vector components in the Setup utility:

INU Case Δy'_AI_! :

Δy'_AI₁: Antenna distance forward of INU in deck plane.
Δy'_AI₂: Antenna distance to port of INU in deck plane.
Δy'_AI₃: Antenna distance upward from INU normal to deck plane.

Gyro Case Δy'_AS :

Δy'_AS₁: Antenna distance forward of ship center in deck plane.
Δy'_AS₂: Antenna distance to port of center line in deck plane.
Δy'_AS₃: Antenna distance upward from ship center normal to deck plane.

Make the measurements to the antenna feed horn. The signs of the components must be strictly observed. The units are meters. Note that the questions in Setup refer to the INU case. If you have the Gyro Case, enter the corresponding moment arms relative to the ship center of rotation.

Setup has an additional question regarding the height offset of the INU. This is a fixed number which is added to the height reported by the INU. Since most INU's accurately report the height, this number should be set to zero. The value of this number does not affect the velocity correction.

Specify the antenna format in Setup, RCP section.
Specify the Extended Ray Header in Setup, ingest section.
If you have a Vaisala RCP8, configure as described in RCP8 User Guide (M212923EN).
Use the TASK Configuration menu to turn on and off the velocity correction for each task.
