How to perform Post Positioning Kinematic GNSS Processing of Phantom 4 RTK Photogrammetric survey data to obtain centimeters grade accuracy, using ASP-SUITE Software. In this video, I would like to show you how to perform Post Processed Kinematic (PPK) GNSS of Phantom 4 RTK UAV Photogrammetric Survey Data. I will make at least two videos about this topic. The first video is about how to do PPK using ASP Suite Software. ASP Suite is a commercial software dedicated to doing this kind of processing. The second video is about how to do PPK using RTKLibs. RTKLibs maybe be a better solution because it is open-sourced so the software would be easily reached by many users, so stay tuned if you are excited about this topic. Besides ASP Suite and RTKLibs, there is some other software that has abilities to do this kind of processing, but I will limit the tutorial to focus on these two. Now let's go first with ASP Suite
