RESEARCH OBJECTIVES
Sensor Test for Orion Relative Navigation Risk Mitigation - DTO 703 (STORRM) tests the Vision
Navigation Sensor, Star Tracker, and Docking Camera planned for Orion both during shuttle
approach to and departure from the International Space Station (ISS). This test determines how
well the navigation system performs during the mission.
EARTH BENEFITS
Results allow for improved math
models and design of future
hardware.SPACE BENEFITS
STORRM demonstrates and
characterizes in-orbit performance
of new navigation system
technology prior to the first Orion
mission to ISS.RESULTS
The Space Shuttle Orbiter
Trajectory Control Sensor (TCS)
interference testing is complete. The testing consisted of 4 reflective elements that are being
considered for use on the STORRM DTO (DTO 703). The purpose of the testing was to ensure
that the reflective elements, which are required for the DTO, did not interfere or cause any
unwarranted operation of the Shuttle TCS. The laser and detector for the TCS are designed for
the visible spectrum as compared to the STORRM Vision Navigation System designed for the
near infra-red spectrum. Preliminary results eliminate the concern that the DTO reflective
elements will interfere with TCS operations. DTO 703 collected data from the Vision Navigation
Sensor and Docking Camera during Orbiter Operations.
This investigation is complete and all results are published.
