context: SSR Phase Bias provides the GNSS receiver with the GNSS signal phase bias that are added to the carrier phase measurements of the corresponding signal to get corrected phase ranges. An indicator used to count events when phase bias is discontinuous is provided. An optional indicator is also provided to indicate whether fixed, widelane fixed or float PPP-RTK positioning modes are supported on a per signal basis. NOTE 1: On the UE side, phase bias corrections of appropriate type are needed to restore the integer nature of the phase ambiguities in PPP-RTK. Their absence will affect the quality of the positioning solution and prevent a fast convergence time. NOTE 2: PPP-RTK Fixed position mode corresponds to the UE fixing the carrier phase ambiguity to an integer value. The PPP-RTK Widelane Fixed positioning mode corresponds to forming the widelane combination of carrier phase measurements and fixing the resulting ambiguity as an integer value. In PPP-RTK Float positioning mode the carrier
description: Precise Point Positioning â Real-Time Kinematic (PPP-RTK) is a technology used in GNSS receivers to provide highly accurate positioning by correcting phase biases and resolving integer ambiguities in carrier phase measurements. It supports various positioning modes, including fixed, wide lane fixed, and float.
explanation: PPP-RTK is classified as a Positioning Technology because its primary function is to determine precise location coordinates using GNSS signals. The description emphasizes its role in correcting errors and enabling accurate positioning.
