full_form: Point-to-Point Protocol
context: can be found in [31]. Table 8.1.2.1a-3: MAC Network RTK service: Specific Information that may be transferred from the LMF to the UE - FKP Network RTK service: With the concept of FKP, horizontal gradients of distance-dependent errors like ionosphere, troposphere and orbits are derived from a network of GNSS Reference Stations and transmitted to a target device together with raw or correction data of a corresponding Reference Station (physical or non physical). The target UE may use the gradients to compute the effect of the distance-dependent errors for its own position. Table 8.1.2.1a-4: FKP Network RTK service: Information that may be transferred from the LMF to the UE - PPP service: This concept uses precise satellite orbit and clock parameters derived from global networks of Reference Stations as well as atmospheric models to perform single station positioning [31]. Compared to RTK and Network RTK, PPP is not a differential technique as there is no baseline limitation. When the
description: PPP (Point-to-Point Protocol) service refers to a precise point positioning technique that utilizes global networks of Reference Stations and atmospheric models to provide accurate location information without the need for differential corrections or baselines.
explanation: The context explicitly mentions PPP as a 'service' in comparison to RTK and Network RTK, highlighting its role as a distinct offering within telecommunications. This classification is further justified by the description of PPP's functionality and application.
