Returned data

Data product Data returned Details
TripleSat satellite image data Four channels for MS data, one channel for PAN data GDB retrieves four image channels for MS data, and one image channel for PAN data.
Ephemeris data One orbit segment GDB imports ephemeris data as an orbit segment. This segment contains information about the satellite position, satellite attitude, IFOV, projection, sensor, and orbit (if the data product provides this information).
RPC data One binary segment GDB imports a rational-function model as a binary segment (when the data product provides this information)
