Starsys Division Completes Ground Link Antenna Pointing System for GeoEye-1 Satellite Imaging Program

Poway, CA – SpaceDev (OTCBB: SPDV) announced that it successfully completed assembly, test and delivery of an Antenna Pointing Assembly (APA), for the ground link antenna pointing gimbal for the GeoEye-1 satellite, currently being built by General Dynamics Advanced Information Systems. Geoeye-1 is GeoEye’s next-generation, high-resolution commercial Earth-imaging satellite scheduled for launch later in 2007. It is equipped with the most advanced technology ever used on a commercial remote sensing system. Once launched, GeoEye-1 will provide a ground resolution of 0.41-meter panchromatic and 1.65-meter multispectral or color imagery.

The APA was delivered to General Dynamics in February for integration onto the spacecraft. The challenge for the Starsys program was to develop a system that exhibited the low disturbance torque necessary for the APA to articulate the spacecraft antenna at the same time it would be acquiring images. The solution was the use of Starsys’ proprietary Quiet Array Drive (QuAD) microstepping technology, which combines the simplicity of stepper motor control, with the jitter-free operation usually only associated with complex brushless actuator systems.

“We thank General Dynamics and GeoEye for entrusting us with this important spacecraft subsystem and we are pleased to be contributing to this exciting new commercial remote sensing capability. As a result of the capability to simultaneously image and articulate the antenna, the GeoEye-1 spacecraft is capable of acquiring as much as 700,000 sq. km of imagery per day in the panchromatic mode,” said Mark N. Sirangelo, SpaceDev Chairman and CEO. “The QuAD microstepping drive is an important new technology in the commercial imagery domain. We believe that these ground-breaking technologies will have significant uses in the future and look forward to further application of this breakthrough product.”
