1 Definition
GNSS Object refers to Data for a Global Navigation Satellite System (GNSS) based on a constellation of satellites that transmit position and timing data to GNSS receivers to enable them to determine the receivers’ location.
2 Functional Requirements
GNSS Data can come from four GNSSs – GPS (US), GLONASS (RU), Galileo (EU), BeiDou (CN) and two regional systems – QZSS (Japan) and IRNSS or NavIC (India). Accuracy of the Position depends on the GNSS system used.
