METHOD FOR PROTECTING A RADIO NAVIGATION RECEIVER USER AGAINST ABERRANT PSEUDO-RANGE MEASUREMENTS

摘要

the present invention relates to a method of protecting aradio navigation receiver user in relation to the measures of pseudodistanceaberrant. the process is characterized in that it is a mistakeas astatistical estimation method on the basis of the calculation of the residuals of the measurements.this processallows, in particular, independently of any ground segment (implementing araim) to increase the functionality, performance, said receiverthe primary)business integrity, to detect possible errorscontaminantthe measures in the calculation of the position by the use of an algorithmstatisticsrobust estimation, that is to say, is not affected by the errors ofmeasures, andimplementing a dynamic criterion is robust, and to calculate a correctionfor thethe primary receiver position provided by excluding such a mistake ifit is detected.
