Formation RF Sensor


To validate the end-to-end performance of the formation acquisition sensor, prototype sensor hardware and software will be developed and integrated in a fixed indoor testbed and an outdoor articulated testbed.

Indoor Functionality Testbed diagram

The purpose of the indoor testbed is to perform hardware and software integration, to serve as a software development platform, to perform end-to-end functional verification, and also to validate the performance model excluding multipath error. In the indoor testbed, all the transmitters on all the sensors will be connected to all the receivers on all the sensors through coaxial cables and attenuators.

Outdoor Articulated Testbed with images of spacecraft models attached to vehicles

The purpose of the outdoor testbed is to validate end-to-end performance of the formation acquisition sensor and illustrate instantaneous 4p coverage through smooth handoff between antennas. In the outdoor testbed, the formation acquisition sensor will be mounted on mobile spacecraft mockup capable of 6 degree of freedom (DOF) movement.
