Question: What is the primary purpose of providing Differential GNSS Corrections assistance to a User Equipment (UE) in an E-UTRAN?
Option 1: To enhance the security of GNSS signals against jamming and spoofing.
Option 2: To increase the transmission power of GNSS satellites for better signal reception.
Option 3: To reduce biases in GNSS receiver measurements by providing pseudo-range and pseudo-range-rate corrections.
Option 4: To enable the UE to operate in areas without direct line-of-sight to GNSS satellites.
Explanation: Differential GNSS Corrections are designed to improve the accuracy of GNSS positioning by correcting for errors (biases) in the measurements made by the GNSS receiver. By providing pseudo-range and pseudo-range-rate corrections, these biases can be significantly reduced, leading to more precise location determination. This is crucial in various applications where accurate positioning is key, such as emergency services, navigation, and location-based services within telecom networks.
