In a GPS navigation satellite receiver, a pseudorange step detection method integrates the pseudorange rates to predict expected changes in the pseudoranges from one measurement to the next. The pseudorange rate is directly measured as the carrier Doppler shift. The pseudorange and ...http://www.google.es/patents/US5808581?utm_source=gb-gplus-sharePatente US5808581 - Fault detection and exclusion method for navigation satellite receivers
