Global Navigation Satellite Systems (GNSS) like GPS (Global Positioning System), GLONASS (Global Navigation Satellite System), Galileo, and BeiDou provide accurate positioning, navigation, and timing information worldwide. However, several sources of errors can affect GNSS-based observations:

1. Satellite Clock Errors: GNSS satellites have atomic clocks onboard for precise timing. However, even minor inaccuracies in these clocks can lead to significant errors in position calculations.

2. Ephemeris Errors: Ephemeris data contains precise satellite positions and is transmitted to GNSS receivers. Errors _________ ______ ________ __________ ____ ____.
