LEE Revalidation Effort

Congratulations to the Robotics, Simulation, and Graphics Support (RSGS) Team on completing the Space Station Remote Manipulator System (SSRMS) Latching End Effector (LEE) re-validation! The METECS RSGS Team has developed, maintained, and validated these LEE contact and mechanism simulation models for a number of years and continues to maintain/improve them. This LEE simulation model is used at NASA for both SSRMS analysis simulations as well as training simulations, which means that it is important that it behave just like the real system. This re-validation activity involved comparing the LEE model response to the expected response data provided by the Canadian Space Agency (CSA) for several different test cases. When differences in the simulation response were detected, the RSGS Team worked closely with CSA to identify the root cause of the mismatch and make and/or coordinate the appropriate adjustments. Great work RSGS Team on completing this re-validation!
