Question: What is the primary purpose of providing SSR STEC (Slant Total Electron Content) Corrections to a GNSS receiver in an NG-RAN environment?
Option 1: To enhance the security of satellite signals against jamming
Option 2: To provide real-time satellite orbit corrections for improved location accuracy
Option 3: To adjust for tropospheric delays in signal propagation
Option 4: To compute ionosphere slant delay correction for code and phase measurements, ensuring integrity with additional error parameters
Explanation: SSR STEC Corrections mitigate the effects of the ionosphere on GNSS signals. They enable receivers to accurately adjust for ionospheric delays in code and phase measurements using a variable order polynomial per satellite, while also providing integrity parameters (e.g., residual risk, correlation time, mean, and standard deviation of residual Ionospheric Error) for reliable positioning service in NG-RAN.
