Check Range Sensor Pod

US Navy submarines are carefully engineered to minimize their detectability by acoustic and electromagnetic (EM) sensors. Because the acoustic and EM signature of the sub can degrade over time, they are periodically measured at fixed test ranges. Providing the capability for a sub to assess its own signatures without transiting to one of these facilities would yield significant logistical and operational advantages, translating to substantial cost savings. The goal of the SeaLandAire team is to develop an inexpensive, simple, yet highly functional expendable sensor pod to cooperatively characterize submarine acoustic and electromagnetic signatures for increased tactical awareness at sea. This Check Range Sensor Pod (CRSP) will be deployed from a submerged submarine to measure and evaluate its detectability relative to an established benchmark (such as the average signature for the submarine class, or a specific operational requirement). The pod must be designed to operate within the limitations of a submarine in a forward operating location. It must be convenient and simple to use and provide meaningful and timely data, while remaining covert.
