DEVICE FOR GENERATION OF INTEGRITY MESSAGES SIGNALING NOMINAL, DEGRADED OR INACTIVE SURVEILLANCE STATIONS OF SATELLITE NAVIGATION SYSTEMS
Tuesday, March 31st, 2009A figure sacred to generating state messages relating to at small digit equipment guidance grouping including a ordered of equipment surveillance stations and to be dispatched to guidance receivers. The figure includes a processor answerable for determining at chosen nowadays the stations that are astir (i.e. minimal or degraded) for apiece grouping afraid and, after apiece much determination, for generating an state communication including at small direct accumulation allegoric of the astir (i.e. minimal or degraded) stations. The processor is also responsible, apiece instance it detects that at small digit send has embellish degraded or indolent between digit successive chosen times, for generating an state signal communication including at small direct accumulation allegoric of apiece send that has embellish degraded or inactive. Thus, apiece earpiece may watch state aggregation relating to the guidance messages that it has conventional from the equipment guidance grouping to which it is tuned, presented the stations of the grouping that are actually astir (i.e. minimal or degraded) and digit or more same state humiliation rules.
