Space Integrated GPS/INS (SIGI)
The inertial instruments include three single axis Honeywell Ring Laser Gyros that measure vehicle body attitude changes and three Honeywell QA3000 single axis accelerometers to measure changes in vehicle body velocities.
The SIGI design has flexibility to accommodate various customer applications and is space radiation tolerant. It can be used for Range Tracking, Target Vehicles, Reusable Launch, Reentry, On-Orbit, Rendezvous and Docking, Expendables Launch and other Space Applications.
