Two-Axis Gimbal for Kilowatt-Class Hall Thrusters Request for Information (RFI)

The Jet Propulsion Laboratory (JPL) is seeking information from qualified vendors regarding their capability to provide two-axis Thruster Gimbal Assembly (TGA) mechanisms that could meet the requirements outlined in the RFI attachment. The RFI is for planning purposes only and does not constitute a solicitation or commitment to procure any services. Key requirements include radiation tolerance of parts used in the baseline design, and the ability to provide information on the suitability of available gimbals for missions to LEO, GEO, and deep space. Some of the key points to consider are: • The RFI is for a two-axis gimbal assembly mechanism • The mechanism should be suitable for missions to LEO, GEO, and deep space • The vendor should provide information on radiation tolerance of parts used in the baseline design • The vendor should provide information on the ROM price and lead time of 1 flight gimbal units vs. 10 flight units • The vendor should comment on how cost may change if requirements are tightened or loosened
