700003315 - Extension of PDM/INA in-service support contract (ISS)

The role of the PDM system is to receive G&TR sensor inputs from the platform Gyro/Naval Compass Stabilisers, Ship's Log System and Wind Data System, and output this data in the required format to various navigation and weapon systems. Provision is also made for the input of simulated data and for transmission to various user equipment’s for training purposes. This role is generally common to all outfits of PDM. Navigation capability on RN ships is a critical component of a ship’s ability to operate and fight, hence any failure or degradation of these systems will place significant risk on the RN’s ability to fulfil the Authority’s required defence outcomes in accordance with the Authority’s Defence Strategy and RN Command Plan.
