SATELLITE MEASUREMENT SCREENING TO PROTECT THE INTEGRITY OF EXISTING MONITORS IN THE PRESENCE OF PHASE SCINTILLATION
First Claim
1. A method of implementing a real-time screening process for phase scintillation, the method comprising:
- detecting a phase scintillation event during a sample time period at a phase scintillation monitor;
excluding associated satellite measurement data from further use based on the detection of the phase scintillation event at the phase scintillation monitor;
detecting an end to the phase scintillation event at the phase scintillation monitor; and
readmitting associated satellite measurement data collected after the end of the phase scintillation event as detected by the phase scintillation monitor.

Abstract
A method of implementing a real-time screening process for phase scintillation is presented. The method includes detecting a phase scintillation event during a sample time period at a phase scintillation monitor; excluding associated satellite measurement data from further use based on the detection of the phase scintillation event at the phase scintillation monitor; detecting an end to the phase scintillation event at the phase scintillation monitor; and readmitting associated satellite measurement data collected after the end of the phase scintillation event as detected by the phase scintillation monitor.

10. A phase scintillation monitor to provide real-time screening for phase scintillation, comprising:
-
at least one processor communicatively coupled to receive input from a plurality of reference receivers; and a storage medium tangibly embodying program instructions for execution by the at least one processor, wherein the program instructions are operable, when executed by the at least one processor, to; detect a phase scintillation event during a sample time period; exclude associated satellite measurement data from further use based on the detection of the phase scintillation event; detect an end to the phase scintillation event; and readmit associated satellite measurement data collected after the end of the phase scintillation event. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method to compute a phase scintillation monitor discriminator, the method comprising:
-
calculating satellite (SV) motion and SV clock corrected carrier rates for reference receiver/satellite pairs for which accumulated delta range data is available; and compensating a SV motion and a SV clock corrected carrier rate for a reference receiver clock by subtracting an average of all the other SV motion and SV clock corrected carrier rates from the SV motion and SV clock corrected carrier rates. - View Dependent Claims (20)
