Navigating CONTOUR using the noncoherent transceiver technique

The objective of the CONTOUR mission was to conduct scientific fly-by studies of comets, Encke and Schwassmann-Wachmann 3, with the option of changing targets in-flight or visiting anadditional target after the SW3 encounter. The paper will describe the mission's planned trajectory, the navigation challenges, as well as the navigation tasks that were involved in achieving mission objectives.

Navigating CONTOUR using the noncoherent transceiver technique

The successful navigation of the Comet Nucleus Tour spacecraft was performed at JPL and was conducted with the use of the new noncoherent transceiver technique developed by the Applied Physics Laboratory. Discussions include the conditioning performed on the 2-way noncoherent Doppler data, the orbit determination process, and the post SRM trajectory reconstruction.
