Back on Banks Island, Koski and Kemp waited to test the new acoustic communications system as poor weather canceled takeoffs and research teams stacked up waiting for flights.
Underwater acoustic communications are severely affected by multipath propagation, which arises from sound reflections from the water surface, bottom and other objects, and sound refraction caused by sound speed variations with depth and temperature in the water.
Current underwater acoustic communications technologies suffer from serious challenges such as susceptibility to environmental noise and require expensive signal processing to deal with the multipath acoustic channel [30].
During the Annual Navy Technology Exercise (ANTX) activities in August, the Submaran relayed instructions to Marlin from a ground control station via underwater acoustic communications. Following these instructions, the Marlin launched the Vector Hawk using a specially-designed canister from the surface of the Narragansett Bay.
The company will leverage its expertise and capabilities in signal processing, acoustic communications, interference cancellation, and anti-jam/anti-spoof technologies for the program.
