Biaxial Gimbals

Overview

These assemblies are built on Moog’s proven rotary incremental actuator platforms, including the Type 1, Type 2, Type 3 and Type 5 actuator families, allowing configurations that range from compact antenna positioners to robust biaxial systems capable of handling higher mass payloads. All units provide precise azimuth elevation or X Y axis positioning and can be tailored to meet mission specific mechanical and electrical interface requirements.

Hard stops can be incorporated for range defined motion. Cable management options include flex loop routing, cable wrap drums, and twist capsule based solutions. A full suite of position feedback devices, potentiometers, optical encoders, and sine cosine resolvers can be integrated depending on system needs. Modular construction allows substitution of actuator sizes, mixing of actuator types in orthogonal configurations, and the integration of RF rotary joints or launch latching mechanisms. Many configurations are already qualified, offering cost and schedule advantages, and all units can be driven by the standard Moog Electronic Control Unit or customer supplied electronics. Together, the family provides a flexible, flight proven solution for precise two axis antenna and payload positioning.
