Accuracy for most aviation GPS receivers is less than 15 meters and if the unit has WAAS, accuracy can be less than 3 meters,
by determining position using at least five satellites or four satellites and barometric altitude input from an altimeter.
The unit will give an alarm if it senses that one or more satellites is transmitting questionable data

>> 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..
