SMART-1s Getting Smarter

API, Inc. has solved the problem of loss of navigation during GPS jamming at military exercises by updating their Crossbow 500 AHRS (Attitude Heading Reference System) to allow continued navigation with 3% accuracy during GPS out conditions. Additionally, SMART-1 pilots will continue to receive critical pitch, roll and altitude information, allowing most missions to be completed.
