Description
This method simuluates GNSS Pseudorange data whenever the calling Spacecraft is in view of the observing sensor on-board one of the observing GNSS Spacecraft.

Method Signature
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
|
gnssObservations
|
|
Description:
|
The List of GNSS Observations to be populated with data. The size of the list is the maximum number of GNSS Observations that will be simulated.
|
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
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, myListOfGNSSObservation1, myVariable2);
