Lightweight Components

The goal of the proposed work is to develop a single-chip, rad-hard, GPS receiver. Nu-Trek has designed and will leverage a 2-channel rad-hard (HAENS level 2) GPS receiver front-end in the proposed work. The front end will be combined with a Raytheon baseband digital signal processor (DSP) developed for the Miniature Air Launch Decoy (MALD) program. The key challenges to be addressed in the work are integrating all functions onto a single chip, achieving the low power requested (<75 mW) and radiation hardening the receiver to 300 kRad TID and single event effects. Nu-Trek and Raytheon"s proposed approach integrates all functions onto a single chip, reduces power to the state of the art through subthreshold operation of the circuits designed and employs rad-hard-by-design techniques in conjunction with a robust processing technology (Jazz"s 0.18um SOI process).
