GPS-20, GPS-38, GPS-45, GPS-45XL and the original GPS-II used a slow CPU to do the DSP+BB+ display functions. 
The DSP supported only two channels of receiver, which were sequentially multiplexed amongst the various satellites. 
The "Brain Dead" CPU apparently did not have enough horsepower to handle a PRR "bandwidth" more than that associated with the ~100 MPH speed,
so these receivers have a software "clamp" that makes them useless in airplanes..
