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
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.
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.
