Parameters

satellite
Type: System.IServiceProvider
The GPS satellite for which to obtain the user range error. The satellite instance must provide IGpsPrnService and ILocationPointService.
performanceAssessmentFile

The Performance Assessment File (PAF) containing the ephemeris and clock errors for the navigation satellites over a period of time.
group

Return Value

Type: Evaluator<SatelliteUserRangeError>
An evaluator of the user range errors for a satellite, along the line-of-sight between the receiver antenna and the satellite.
Exceptions
