Almost-Instantaneous PPP-RTK Without Atmospheric Corrections
, 2022 AbstractAmbiguity resolution enabled precise point positioning (PPP-RTK) can provide fast, potentially even instantaneous, centimeter-level positioning results, given that the phase ambiguities are correctly resolved. Without external ionospheric corrections, a time-to-first-fix the ambiguities of around 30 min is often reported for GPS-only solutions.

A Consistent Regional Vertical Ionospheric Model and Application in PPP-RTK Under Sparse Networks
Navigation, 2023 Ionospheric augmentation is one of the most important dependences of PPP-RTK. Because of the dispersive features of the ionosphere, the ionospheric information is usually coupled with satellite- and receiver-related biases.
