Based on the many years of (accumulated) development experiences of space program, TelePIX has successfully developed the SOP, Space-borne Optical Payload for a 6U-class Nanosatellite platform.
SOP consists of the “DPHU (Data Processing and Handling Unit)” which is used for the interface of telecommunication with bus platform, and the “OM (Optical Module)” which is used for the image taking and processing.
SOP has been designed to provide the image of PAN and MS 5.0 m resolution respectively with more than 50 SNR performance at a design altitude of 500 km despite of 3U sized and less than 4 kg. In case of the thermal control systems for SOP, it was realized by the passive thermal control design based on various case studies and optimization to minimize power consumption of SOP.
Also, we have conducted the thermal vacuum test combined by thermal vacuum cycling tests and thermal balance tests to evaluate thermal performance and integrity, and workmanship of the FM under the acceptance test level. We have completed the thermal vacuum cycling tests without any issue and performed the evaluation of the thermal analysis model of SOP by comparing with the thermal balance test results with reference to the ECSS standard. After the correlation process, the deviations between the test and analysis result were satisfied the criteria.
Currently, we are waiting for the launch and LEOP activities scheduled in January/February 2025.
