23. 9 Satellite Reference Mode The ships gyro compass input to the ACU may be accurate and stable in static conditions and yet may NOT be accurate or stable enough in some underway dynamic conditions If there is no gyro compass or if the input is corrupt not stable or not consistently accurate the tracking errors will become large enough to cause the antenna to be mis pointed off satellite Satellite Reference Mode will uncouple the gyro reference from the azimuth rate sensor control loop This decoupling of the Gyro source only happens 5 minutes after an azimuth command has been sent to the antenna by means of an AZ target command a search pattern initiated or the a Satellites longitudinal position is targeted When operating in Satellite Reference Mode changes in ships gyro reading will reflect its changes to the ACU s display but will not directly affect the azimuth control loop The Pedestal Control Unit will stabilize the antenna based entirely on the azimuth rate sensor loop and the tracking information from DishScan This will keep the azimuth rate sensor position from eventually drifting away at a rate faster than the tracking loop can correct by using the tracking errors to regulate the rate sensor bias Satellite Reference Mode can be used as a diagnostic mode to determine if tracking errors are caused by faulty gyro inputs 7 10 Maintenance and Troubleshooting 2406 49 Broadband At Sea Satellite Reference Mode MUST be used when
