The Inertial Navigation System (INS) AN/WSN-7 Ring Laser Gyro Navigation (RLGN)
|
The INS senses motion (inertial), gravity and earth rotation in the performance of its navigation functions. Additionally, the INS receives externally supplied GPS updates via NAVSSI and ship's speed through the water via the pit sword.

Master gyrocompass
|
MTW’s shipboard configuration consists of two fully independent, self-contained INS cabinets, which provide full redundancy and increased survivability. One is located FWD IC Shop, and another in AFT IC shop. The system is capable of worldwide operation without the need for external position reference information for prolonged periods of time. During mission performance, the INS will not be susceptible to jamming or detection by enemy forces

Synchro signal amplifiers
|
Amplifies course heading data from the gyro and transmits them to the slave units to coincide with the master unit. It has a critical bus supplies data to the helm, aft steering, and aft gyro.

Alarms and Enunciators
|
It provides a visual and audible indication of problems within the gyrocompass system. Also monitors ships 115 volts 60HZ and 400 HZ power provided to gyrocompass system. (2) IC/SM alarm panels (fwd & aft) monitor gyrocompass as well as synchro signal amplifiers.
