Spacecraft.SimulateTrackingData(Formation, PointSolutionObservation, Variable) Method

Top 

Description

This method simulates PointSolution data whenever the Spacecraft is in view of at least 4 Spacecraft in the Formation provided as an argument. If the Formation is not being propagated with a RinexNavFile, a nadir-pointing Sensor must be added to each Spacecraft in the Formation.

 

Timing Precision Mode

This page describes functionality in nanosecond timing precision mode.

 

Method Signature

Spacecraft.SimulateTrackingData(

Formation gpsFormation,


PointSolutionObservation psObservation,


Variable exclusionHeight)

 

Arguments

gpsFormation


Description:

The Formation object for the Observing GPS spacecraft. This argument is used to determine visibility of GPS Spacecraft. Also when simulating Pseudorange data it is used to model GPS clock biases and set the PRN code based on the SatelliteId.

 

psObservation


Description:

The Point Solution Observation to be populated with simulated data.

 

exclusionHeight


Description:

The height above the limb of the Earth, below which all signals passing the Earth will be excluded.

Units:

km

Valid Range:

exclusionHeight ≥ 0

 

 

Return Value

Type:

number

 

Returns 1 if data was successfully simulated, 0 if no data was simulated due to a visibility restriction, such as an occulting body or sensor mask. When simulating multiple Pseudorange Observations, this method returns the number simulated.

 

Syntax

myVariable1 = mySpacecraft1.SimulateTrackingData(myFormation1, myPointSolutionObservation1, myVariable2);
