This thesis presents the results of analysis and experiments evaluating the potential
for using reflected
GPS signals as a remote sensing instrument. Using GPS signals
in this manner is, in effect, a bistatic radar that utilizes one of the GPS bands (L1,
1575.42MHz) and has many advantages for small satellite applications because it pro-
vides a sensor which is passive, has a small foot print and consumes very little power.
GPS signals can provide information about ocean surface conditions and
other information about terrestrial land mass. The GPS bistatic radar also has the
potential for being a sensor for relative ranging and proximity sensing on orbit. This is
particularly useful because it allows measuring ranges to objects or satellites that are
not equipped with a GPS receiver (e.g, a dead satellite or passive target), for a variety
of missions including satellite servicing and formation operations.
