WELKIN SCIENCES, LLC — Department of Defense SBIR Phase I: Welkin Sciences proposes to design and build a Submersible GPS Enhancement and Playback Sy

Description

Welkin Sciences proposes to design and build a Submersible GPS Enhancement and Playback System (SGEPS) to address the Navy's need for covert and accurate submarine navigation. The baseline SGEPS design employs multiple antenna elements, multi-channel signal recording and adaptive interference cancellation to synthesize interference-free L1 and L2 signals that can be processed by any GPS receiver. More importantly, the Welkin Sciences'SGEPS design can be upgraded with two optional capabilities that the Navy may find desirable: 1) the antenna assembly and signal capture circuitry that can be deployed on a tethered buoy; and 2) an adaptive beamforming function that cancels interference while also coherently combining the recorded GPS signals sensed by multiple antenna elements.
