Evaluating the Performance of the Static PPP-AR in a Forest Environment

Journal of Surveying Engineering
Forest environment and topographic obstacles tend to reduce the positioning performance of precise point positioning (PPP) with ambiguity resolution (AR) and may even prevent radio signals from reaching the global navigation satellite systems (GNSS ...

Assessment of tropospheric modeling on PPP-AR performances under brazilian atmospheric condition

Boletim de Ciências Geodésicas, 2022
Abstract: In the Global Navigation Satellite System (GNSS), ambiguity resolution (AR) can shorten observation time and increase the positioning quality. The correct tropospheric modeling is intrinsically related to the ability to perform AR. Here, we assessed the influence of different tropospheric correction alternatives on AR for static Precise Point

Comparison of RT-PPP and RT-PPP-AR Methods [PDF]

Academic Perspective Procedia, 2020
The Precise Point Positioning (PPP) is an absolute positioning method which emerged as an alternative to the relative positioning method. This method is widely used in many applications in recent years. In this method the static and kinematic positioning can be performed with high accuracy by using single GNSS receiver.
