The ARCS is an autonomous remotely controlled submersible for under-ice survey being developed for the hydrographic service. Five separate sonar systems are used for telemetry, survey, and guidance. Telemetry is achieved through a 50 bps fsk link. The low data rate, which is necessitated by the severe multipath constraints of the shallow under -ice environment, demands a high degree of on board intelligence and some novel operator interface methods. The onboard computer is modelled after the hierarchical command structure of a naval submarine. The 'navigator' uses sophisticated statistical estimation algorithms. Most of the onboard equipment is off the shelf, but there was a requirement for some custom designs. Preliminary sea trails were carried out in April 1984 and full scale under-ice trials are scheduled for late 1984.
