RIA Novosti is reporting that German firm Jena-Optronik GmbH has delivered an advanced star sensor to Russia’s Reshetnev Information Satellite Systems company (ISS), which will test and integrate it on a GLONASS navigation satellite, Reshetnev said on Wednesday.
The Astro APS sensor is part of the satellite’s altitude and orbit control system. It will help ensure that the GLONASS satellites maintain an accurate attitude in space.
The sensor will be installed on a GLONASS-M satellite under a 2011 agreement signed between Reshetnev ISS and Jena-Optronik GmbH. It has a single box design with low mass and low power consumption. If tests are successful, it will be integrated on other ISS spacecraft.
