The COMPact Airborne Stabilization System (COMPASS) was developed under NASA SBIR funding to provide the remote sensing community with a tool to correct pushbroom image data for aircraft motion in real-time. COMPASS was designed to accommodate a wide variety of existing and future spectral sensor systems, and provides added value to these sensors: the end product (a geo-registered data set) can be produced at a higher quality, higher reliability, and in a shorter amount of time.
The system was successfully flown in July 2003, and is scheduled to be delivered to the customer at NASA Goddard Space Flight Center in September of 2003. COMPASS coomprises the following:
- IMU/GPS with NovaSol Kalman Filter implementation
- Laptop Operator Interface, including mission planning software
- Navigation Software
- Motion Control Software
- Optical Gimbal
- Pilot Navigation Aid
- Complete specifications can be found on the products page
