PTS-03 is a 5km miniaturized version of the Engineer-05. It is a lightweight, modular, payload-dependent spacecraft designed to carry a range of small scientific payloads. While it carries the same basic electronics and basic interface as the Engineer-05, it is optimized for miniaturized payloads. PTS-03 contains four attitude control thrusters, two reaction wheels, and telecommunications payloads. It utilizes a sophisticated Power, Thermal and Structural (PTS) suite of components to support the satellite's mission. The PTS-03 is designed to be a cost-effective alternative to larger satellites, while still providing enough performance to meet the mission requirements.
