Degradacija kvalitete GPS satelitskog određivanja uslijed prekida rada satelita: analiza slučaja GPS PRN24 u Hrvatskoj

Navigation satellite outage has a profound effect on the satellite navigation systems performance. A programmed temporal outage of the PRN24 satellite scheduled for 12thSeptember 2009 motivated a simulation-based study of the satellite outage effects on the overall GPS positioning performance and signal availability. The study was focused on the identification of the GPS performance degradation due to satellite outages in Croatia due to the growing utilization ofthe satellite navigation systems as a component of the national infrastructure. Two GPS reference sites in rural areas were simulated for the determination of open sky view obstructions. The satellite visibility and the corresponding positioning dilution of precision (PDOP) for both sites prior and after the planned temporal outage of GPS PRN24 satellite were determined. The results obtained from simulation using broadcast GPS almanac were compared with those related to the un-obstructed view of the sky. The analysis revealed no significant disruption for the un-obustructed sky view, but a significant impact was identified particularly to sites with natural southward sky-view obstruction.
