Abstract: Six Singapore satellites were launched by India’s Polar Satellite Launch Vehicle C-29 on 16th December 2015. Among them, the VELOX-II is a 6U nanosatellite built in Nanyang Technological University (NTU). Its primary payload is to demonstrate inter-satellite data relay system. However, the short development timeline (i.e. 18 months) of the VELOX-II poses several challenges. The primary payload hardware is required to pass the qualification environmental test and meet the requirements given by the satellite platform and service provider within 6 months of development. To achieve this, a standalone test flow and specification for primary payload is required to ensure both hardware and software are simultaneously progressing. Modification of satellite platform is required to meet the higher power consumption required. Furthermore, the characteristic of high revisit rate of near equatorial orbit satellite requires an automated ground operation system to be developed to maintain low manpower requirement for 24 hours operation; while the ground operation software development should not affect the VELOX-II flight software development. In this paper, the challenges faced in VELOX-II program and their solutions are discussed. To date, all required VELOX-II’s experiment demonstrations have been successfully conducted.
