GNSSObservation Object

Description

The GNSSObservation objects holds pseudorange (one-way range) Measurements associated with a Global Navigation Satellite System (GNSS) constellation satellite's signal being processed by a GNSSReceiver on a Spacecraft at an instant in time. The Measurements for a GNSSObservation are denoted by Rinex Measurement Codes.
