Abstract
Disclosed are various techniques for wireless communication. In one aspect, a user equipment (UE) may receive, from a satellite vehicle (SV), a signal of a first frequency band, estimate a first ionospheric delay residual error based on the signal of the first frequency band, calculate a first pseudorange measurement and a first carrier phase measurement based on the first ionospheric delay residual error, and estimate a position using the first pseudorange measurement and the first carrier phase measurement. In some aspects, the ionospheric delay residual error is estimated via a Klobuchar equation. In some aspects, the position is estimated using ultra-long baseline real-time kinematics (RTK) positioning.
