GnssTransmitterGenerator
Definition and basic information of GNSS transmitters.
See also GnssProcessing and GnssSimulateReceiver.
GNSS
A list of satellite PRNs (i.e for GPS: G01, G02, G03, ...) must be provided via
inputfileTransmitterList. Satellite system codes follow the
RINEX 3 definition, see GnssType.
All input files except inputfileAntennaDefinition,
and inputfileReceiverDefinition are read for each satellite.
The file name is interpreted as a template with the variable {prn} being replaced by the satellite PRN.
Metadata input files (marked with * below) are provided in GROOPS file formats at https://ftp.tugraz.at/outgoing/ITSG/groops. These files are regularly updated.
- inputfileTransmitterInfo*: PRN-SVN mapping, antenna offsets and orientations. Created via GnssAntex2AntennaDefinition or PlatformCreate.
- inputfileAntennaDefinition*: Antenna center variations. Created via GnssAntex2AntennaDefinition or GnssAntennaDefinitionCreate.
- inputfileReceiverDefinition*: Transmitted signal types. Created via GnssReceiverDefinitionCreate in case you want to define which signal types a satellite transmits.
- inputfileOrbit: Converted via Sp3Format2Orbit or output of GnssProcessing.
- inputfileAttitude: Rotation from body frame to CRF. Created via SimulateStarCameraGnss or converted via GnssOrbex2StarCamera.
- inputfileClock: Converted via GnssClockRinex2InstrumentClock or GnssRinexNavigation2OrbitClock or output of GnssProcessing.
