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.

Method Signature

Spacecraft.SimulateTrackingData(	Formation gnssFormation,
	PointSolutionObservation psObservation,
	Variable exclusionHeight)

Arguments

gnssFormation
Description:	The Formation object for the Observing GNSS spacecraft. This argument is used to determine visibility of GNSS Spacecraft. Also when simulating Pseudorange data it is used to model clock biases and set the Satellite ID code based on the GNSS System and SatelliteId.
Repeatable:	1 to Unlimited times

psObservation
Description:	The Point Solution Observation to be populated with simulated data.

exclusionHeight
Description:	If the height of the line segment between the observer and target above the surface of a participating CelestialObject is less than the exclusionHeight, then the two objects will not be considered to be in contact. Participating CelestialObjects include the central bodies of the observer and target and both the Earth and the Moon if one of those bodies is in the set.
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
