The ASTRO XP Cam, derived from the ASTRO XP (eXtreme Precision) star sensor, is a camera designed for high demanding navigation and observation scenarios. Thanks to its innovative optics ASTRO XP Cam combines an outstanding performance with a very low consumption of spacecraft resources to set a new standard for high performant space-applied cameras.
Core element of the ASTRO XP Cam is the 175/2.0 (focal length/f-number) optics as part of an optical head with an overall mass of only 2.6 kg. The consequent use of only one and low coefficient of thermal expansion (CTE) material for the catoptric optics ensures an excellent thermal stability due to the absence of any CTE mismatches.
Thanks to these features, ASTRO XP Cam is the best choice for missions demanding for a high performance with respect to radiometric (e.g. detection of a faint object for navigation or SSA) as well as line-of-sight stability (e.g. celestial body navigation) while saving of the spacecraft resources mass, envelope and power.
The following complementary design highlights enable the outstanding performance of the ASTRO XP Cam:
Innovation and future: The ASTRO XP star sensor was rewarded with the “Thüringer Innovationspreis” in 2020. An ASTRO XP star sensor pre-qualification model passed the test-readiness review (TRR) in November 2022 whereat the production already involved all the demanding manufacturing technologies required to meet the specified Performance.
