Talk Title: In-Flight Thruster Calibration for the 2007 Mars Phoenix Lander

Abstract: After the Phoenix spacecraft was launched on its way to Mars in August 2007, the mission team worked feverishly to create, validate and use an all-new Kalman filter tool that could process a combination of deep-space tracking Doppler data and spacecraft IMU data to precisely characterize the thrust of the individual reaction-control thrusters, which were not coupled in all axes (with interesting implications), to enable pinpoint navigation to the entry point at the top of the Martian atmosphere. Come hear how this novel “Sigma-Point Consider Filter” tool was created, tested and used on Phoenix, as the spacecraft was en route to the Red Planet!
