The integration of survey-grade Global Navigation Satellite Systems (GNSS) with photogrammetric measurement studies conducted with an aircraft has the potential to meet the need for the use of ground control points (GCP). In photogrammetric studies, there are different GNSS techniques to provide the precise positioning of the aircraft. The precise point positioning (PPP) technique has become an alternative method to post-processing kinematic (PPK) methods in the evaluation of GNSS data gathered with an aircraft at high speed. In this study, GNSS data gathered from two different flights conducted for photogrammetric surveys in Izmir, Turkey were processed with different software (RTKLIB, gLAB, CSRS-PPP, and GRAFNAV) through PPP technique with the ambiguity resolution (PPP-AR) method to analyse the performance of this method versus PPK. Three-dimensional (3D) positioning analyses of coordinate differences obtained from mapping flights demonstrated a variation pattern mainly between 0 and 6 cm for both kinematic PPP and PPK results.

将测量级全球导航卫星系统 (GNSS) 与用飞机进行的摄影测量研究相结合，有可能满足使用地面控制点 (GCP) 的需求。在摄影测量研究中，有不同的 GNSS 技术来提供飞机的精确定位。精确点定位 (PPP) 技术已成为后处理运动学 (PPK) 方法的替代方法，用于评估用飞机高速收集的 GNSS 数据。在这项研究中，从在土耳其伊兹密尔进行的两次不同的摄影测量飞行中收集的 GNSS 数据通过 PPP 技术和模糊度解析 (PPP-AR) 方法使用不同的软件（RTKLIB、gLAB、CSRS-PPP 和 GRAFNAV）进行处理，以分析此方法与 PPK 的性能。
