Abstract
Technology for generating a H1 protection level from an N−1 position in a global positioning system (GPS) receiver is disclosed. One approach can include an H1 monitor configured to generate an H1 protection level from an N number of N−1 positions. The N−1 position can be derived by a differential global positioning system (GPS) satellite measurement removed from a plurality of N differential GPS satellites measurements.
