Programable Lead Screw Actuated Self-Leveling Platform

The Programmable Lead Screw Actuated Self-Leveling Platform (PLSASLP) was developed to provide a self-leveling and load-bearing foundation for payloads that need leveling of up to 15 degrees. Consequently, the PLSASLP can also provide a 30-degree conical field of view for precision pointing of instruments. PLSASLP is based on a simple, yet stable geometric model, where undesired motions are restricted to minimize hardware mass and complexity needed to keep the leveling base stable. Redundancy can also be implemented without changing the system architecture. Both system simplicity and configurability indicate the PLSASLP architecture is an effective, viable leveling and pointing solution for flight applications.
