Receiver

Receiver — Hardware that receives an RF signal.

Description

A GroundStation or Spacecraft resource needs a Receiver. A GroundStation resource, for example, needs to receive the RF signal from ground station user spacecraft. A Receiver is assigned on the AddHardware list of an instance of a GroundStation or Spacecraft.

The receiver resource is also used as the host object for the GPS_PosVec measurement error model. When using GPS_PosVec data for estimation or simulation, an ErrorModel instance specifying the GPS_PosVec measurement type should be assigned on a Receiver object, and that receiver should be assigned to the associated Spacecraft object.

Description

ErrorModels

User-defined list of ErrorModel objects that describe the measurement error models used for this receiver. The only error model type currently supported is GPS_PosVec. This parameter is only needed when simulating or estimating using GPS_PosVec data.

Data Type	StringList
Allowed Values	An instance of ErrorModel using the GPS_PosVec observation type
Access	set
Default Value	None
Units	N/A
Interfaces	script

Integer identification number for this receiver. This should match the receiver ID specified for the GPS_PosVec data in the GMD file. This parameter is only needed when simulating or estimating using GPS_PosVec data.

Data Type	Integer
Allowed Values	Integer >= 0
Access	set
Default Value	800
Units	N/A
Interfaces	script

PrimaryAntenna

Antenna resource used by Receiver or Spacecraft resource to receive a signal

Data Type	Antenna Object
Allowed Values	Any valid Antenna object
Access	set
Default Value	None
Units	N/A
Interfaces	script

Examples

Create and configure a Receiver object and attach it to a GroundStation.

Create Antenna DSNReceiverAntenna;
Create Receiver Receiver1;

Receiver1.PrimaryAntenna = DSNReceiverAntenna;

Create GroundStation DSN
DSN.AddHardware = {Receiver1};
BeginMissionSequence;
