Miniaturized Radiation Hardened Beam-Steerable GPS Receiver Front End, Phase II

Completed Technology Project

Project Introduction

Position, Navigation and Timing (PNT) capability via GPS services are used by NASA for (1) real-time on-board autonomous navigation, (2) attitude determination and (3) earth science including sea height and climate monitoring. It is expected that over the next two decades approximately 95% of ALL space missions will operate within the GPS service envelope. GPS receivers will be "embedded" in most instruments and will require improved SWAP and increased sensitivity for improved tolerance from large interferers and/or ruggedness to multipath errors. The RFIC developed in this Phase II will have 4 coherent GPS receivers on a single silicon die which improves the SWaP metric over the existing solution by 30x. In addition to supporting beam steering capability, it'll provide interference tolerance and signal recovery in multipath environment, such as those during positioning of precision equipment on the International Space Station (ISS). The other NASA programs that will benefit from this device are: 1. Magnetospheric Multiscale Mission 2. Sexton GPS receiver for Xray Telescope on ISS. 3. COSMIC IIA,B Missions 4. Jason III Mission for Oceanography The schedule in this proposal will have the delivery of the initial prototype samples made available to NASA in 12 months.
