Description

The GPS (global positioning system) constellation system is able to provide positioning information about a particular constellation of GPS spacecraft that are initialised.

Properties

Declared	Description
ActiveSatellites	A list of active satellites based on a flag. This will be used to determineif the satellite is active or not. By disabling some satellites, the GPSposition may become inaccurate.
FilePath	The file path for the GPS constellation data.
IsInitialised	A flag whether the data has been loaded. This will ensure that on a newserialization, the data is reloaded.
NumSatellites	The total number of satellites that are available in the network.
Out_GPSEnvironmentMsg	Published GPS RF environment (diffuse jamming, jammer slots, future spoofing fields).Consumers such as apply this per receiver using geometry;the constellation truth in stays separate.

Inherited	Description
IsEnabled	Is true if the object is currently enabled.
Name	The display name or tag of this object.

Methods

Declared	Description
AddJammingEffect	Adds or overwrites a jammer slot on and enables theenvironment. Parallel arrays are grown if needed. Returns the slot index used.
Clear	Clears the GPS system and removes all spacecraft points from the currentlist of positions.
ClearSpoofing	Clears spoofing fields on (mode ,zero radius, zero vectors, seed 0). Does not changeor jammer arrays — use that flag or when you want the whole environment off.
EnableSpoofing	Enables spoofing on by turning the RF environment on andwriting the spoof fields consumed in .
GetNumJammers	Returns how many jammer rows exist on (parallel array length),including slots with false if present.
GetTransmitterStatus	Returns whether the GPS transmitter at is enabled for(constellation must be initialised).
Initialise	Loads the GPS constellation from a TLE lookup file, which will load in allthe TLEs and create the transmitters associated with the GPS constellation.
RemoveJammingEffect	Removes the jammer row at by splicing it out of every parallel array andshrinking storage. Indices at or above shift down by one. Out-of-rangeindices are ignored.
SetTransmitterStatus	Enables or disables the GPS transmitter at for(constellation must be initialised).
UpdateJammingEffect	Overwrites the jammer slot at with new geometry and ERP, sets whether thatslot participates in jamming, and turns the RF environment on (same field semantics aswhen is ).
