Platform (file format)

Defines a platform with a local coordinate frame equipped with instruments. The platform might be a reference station, a low Earth satellite, or a transmitting GNSS satellite and is referenced by a marker name and number. The reference point (marker or center of mass (CoM)) can change in time relative to the local frame.

Each equipped instrument is described at least by the following information

name
serial number
coordinates in the local frame
a time interval in which the instrument was active
the orientation for antennas and reflectors.

For GNSS satellites the platform defines the PRN. The different assigned SVNs are defined by the transmitting antennas.

Platforms for GNSS stations can be created from station log files with GnssStationLog2Platform. Platforms for GNSS satellites can be created from an ANTEX file with GnssAntex2AntennaDefinition.
