Ultra Wideband Radio for Secure Communications in a Noisy Environment

DOD / NAVY
The most precise INS used on today's submarines is the Electrostatically Supported Gyro Navigator (ESGN). Although ESGN is very reliable and very precise, its Life Cycle Cost (LCC) is very high. The interferometric fiber optic gyroscope (IFOG) will significantly lower the LCC of submarines' navigation systems. One weak point in the current IFOG based navigation system the slip rings based data link. The slip ring suffers some rare intermittent faults, which are due to moisture trapped inside the slip ring. These glitches may cause big navigation errors in rate gyros like IFOG. Our solution to minimize these glitches caused by the slip rings is to replace the slip rings by an extremely reliable wireless data link. The design of this wireless data link for FOGN is difficult because FOGN uses a spherical gimbal set (SGS) and the only openings that RF signals can propagate through layers of gimbals are small pin holes. During Phase II of this project, we will design a wireless data link based on Multi-band Orthogonal Frequency Division Multiplexing (MB-OFDM) radio, and integrate it with Boeing's Micro-Thermal Control SGS to demonstrate that the proposed wireless data link is more reliable than slip rings.
