COMPASS

---

Introduction
COMPASS (COMPact Airborne Stabilization System) was developed under NASA SBIR funding to provide real-time geo-correction of pushbroom sensor data. COMPASS is adaptable to numerous sensors and platforms, and ideally suited for small aircraft and UAV applications.

COMPASS System Components
 

• IMU/GPS with NovaSol Kalman Filter implementation
• Laptop Operator Interface, including mission planning software
• Navigation Software
• Motion Control Software
• Optical Gimbal
• Pilot Navigation Aid
