Lockheed Martin is the prime contractor designing and building the Orion spacecraft for NASA. Having completed its first high orbital test flight in December 2014, Exploration Mission-1 (EM-1) will be Orion’s next test flight. This flight will demonstrate the spacecraft’s capabilities for enabling Orion’s first manned mission, Exploration Mission-2 (EM-2), in 2021.
Jena-Optronik will be part of this advanced space mission developing and supplying the ASTRO APS Star Sensors for the attitude and orbit control systems for both missions, EM-1 and EM-2.
“We are looking forward to be a part of this pioneering mission with our ASTRO APS star sensor. We are able to contribute our know-how to this fascinating mission. This is the first time since the Soviet MIR-space station that star sensors from Jena-Optronik are part of a manned mission”, comments Dr. Boris Pradarutti, head of star sensor at the Jena-Optronik GmbH.
Active Pixel Sensor Performance
ASTRO APS is an autonomous star tracker with the most advanced radiation hard CMOS Active Pixel Sensor (APS) detector technology for long-term missions.
The technical key parameters of the APS based star trackers are the low mass budget and the low power consumption. These data define a new level of compactness compared to state-of-the-art CCD-based star sensors:
