Question: In E-UTRAN, what type of corrections does RTK MAC Correction Differences primarily provide to the GNSS receiver for enhanced positioning accuracy?
Option 1: Atmospheric and Topological Corrections
Option 2: Multipath and Fading Mitigation Parameters
Option 3: Ionospheric (dispersive) and Geometric (non-dispersive) Corrections
Option 4: Satellite Orbit and Clock Error Adjustments
Explanation: RTK MAC Correction Differences refines GNSS positioning by compensating for errors introduced by the atmosphere and geometry between reference stations. Specifically, ionospheric corrections address signal delays caused by the ionosphere (dispersive effects), while geometric corrections account for non-dispersive effects related to satellite and receiver positions, vital for precise UE positioning in E-UTRAN networks.
