Abstract
STPSat-5 is a small technology demonstration satellite developed for the DoD Space Test Program, recently launched in December 2018. The STPSat-5 space vehicle is hosting five separate space experiments in Low Earth Orbit on a single Microsatellite platform. This paper discusses the development and operation of the STPSat-5 mission with an emphasis on methods used to achieve high capability with low-cost solutions. The application of CubeSat-class hardware in a Microsatellite-class space vehicle is reviewed. Attention is given to approaches for establishing flight readiness for commercial hardware. In addition, this paper covers lessons learned in adapting heritage flight software for operation on new, lower-cost processor systems as well as suggested testing approaches. Suggestions for interfacing multiple small experiments on a single platform are addressed as well as approaches to data handling. Utilization of a large-scale commercial rideshare mission for launch is also discussed, including guidelines to facilitate space vehicle to launch vehicle integration. The topic of lean mission operations is also covered with suggestions for areas of emphasis, guidance for troubleshooting, and an update on the current operational status of the STPSat-5 mission.
