Question: What is the primary purpose of providing Differential GNSS Corrections assistance to a User Equipment (UE) in an NG-RAN environment?
Option 1: To enhance the security of GNSS signals against jamming and spoofing.
Option 2: To reduce biases in GNSS receiver measurements by providing pseudo-range and pseudo-range-rate corrections.
Option 3: To enable the UE to determine its location when GNSS signals are weak or unavailable.
Option 4: To facilitate handover between different GNSS constellations (e.g., from GPS to GLONASS).
Explanation: Differential GNSS Corrections improve the accuracy of GNSS positioning by correcting for errors in pseudo-range and pseudo-range-rate measurements, mitigating biases in the receiver's calculations to enhance location determination precision, crucial for services like emergency location, location-based services, and network optimization.
