SOHLA-1 is a technical demonstration satellite developed by local SMEs (small and medium-sized enterprises) with technical support of Japan Aerospace Exploration Agency (JAXA) and Osaka Prefecture University. Development was initiated by SOHLA, the Space Oriented Higashiosaka Leading Association. The main objective of SOHLA-1 is to acquire and to accumulate various technologies for small satellite development. Another mission of SOHLA-1 is on-orbit demonstration of several new technologies such as the VHF lightning impulse measurement . SLR will be used for the calibration of GPS-based satellite positioning. The micro GPS receiver used in this mission has been developed by JAXA based on COTS automobile navigation technology.
