GPS receivers used in car navigation and other applications have been downsized to dozens of grams, with significant gains in power conservation. With the assistance of a vehicle GPS manufacturer, a vehicle GPS receiver has been modified and a space application GPS receiver with ultralow power consumption that generates pseudo-range data has been developed. We expanded the frequency search range for the GPS receiver, and we conducted on-orbit simulations using a GPS simulator and confirmed that the positioning accuracy performance of the receiver is less than 1 m. It has also been confirmed that the receiver has a 20-krad radiation tolerance and that it is latch-up-free with respect to 200-MeV protons. The GPS receiver will be deployed on the small scientific satellite INDEX which is under development by the Aerospace Science Research Department of the Japan Aerospace Exploration Agency. © 2006 Wiley Periodicals, Inc.
