Question: In NG-RAN, what type of corrections does the RTK MAC Correction Differences provide to the GNSS receiver for enhanced positioning accuracy?
Option 1: Only tropospheric corrections for signal delay
Option 2: Both ionospheric and geometric corrections between Reference Stations
Option 3: Geometric corrections only, for precise location calculation
Option 4: Ionospheric (dispersive) and geometric (non-dispersive) corrections generated between a Master Reference Station and its Auxiliary Reference Stations
Explanation: The correct answer is Option 4 because RTK MAC Correction Differences provide the GNSS receiver with detailed information about two types of corrections: ionospheric (dispersive, affecting different frequencies differently) and geometric (non-dispersive, related to spatial arrangement). These corrections improve positioning accuracy by compensating for errors between a Master Reference Station and its Auxiliary Reference Stations in NG-RAN.
