REGISTRATION WILL OPEN AROUND LATE JULY / EARLY AUGUST

Course Description

This course provides a study of high-precision multi-GNSS precise point positioning (PPP) using the latest version of the open-source software PRIDE PPP-AR. The course covers PPP fundamentals and techniques for undifferenced ambiguity resolution, as well as hands-on experience with the PRIDE PPP-AR software. Applications addressed include geodesy, seismology, aerial photogrammetry, engineering surveys, and meteorology. The primary tool is the open-source PRIDE PPP-AR software, available in command-line interface for Linux and graphical user interface for macOS/Windows. The workshop will utilize rapid GNSS PPP-AR products from the IGS WHU analysis center, which can be automatically obtained from the IGS data center. Participants will work with RINEX observation files provided by the instructors.

Primary Audience: Researchers, students, and professionals in geodesy, GNSS, or related fields who have specific research or application needs for GNSS high-precision data processing, and who have some basic understanding of GNSS data processing principles.

Secondary Audience: Individuals interested in geodesy or GNSS technology who have little to no prior experience with GNSS data processing, including students, hobbyists, or professionals from a variety of fields seeking a basic understanding of GNSS data processing and its applications.

Learning Objectives

Participants who complete this course will gain a well-rounded understanding of the theory of multi-GNSS precise point positioning (PPP) and undifferenced ambiguity resolution. They will be able to effectively use the PRIDE PPP-AR software to perform static and kinematic PPP processing and analyze the results for various scientific and engineering applications including geodesy, seismology, aerial photogrammetry, engineering surveys, and meteorology.

Participant Commitment

Participants need to commit to attending the 2.5 hour lecture and complete any assignments and/or quizzes assigned.

Hardware: Standard personal computer (no special hardware required)

Software: Python and PRIDE PPP-AR installation package

Internet: No specific speed requirement; standard stable connection for virtual participation (Zoom)

Data: GNSS observation data (RINEX files); example data provided by instructors

Brief Agenda

Tentative agenda is listed below, and subject to change.

Monday, 9/14/2026 13:00–15:30 UTC (1 session, 2.5 hours)

Introduction to PPP theory and undifferenced ambiguity resolution Demonstration of PRIDE PPP-AR features and settings; Hands-on processing of static and kinematic data; Review of output and results analysis.

Assessment:

Assessment of participants’ understanding will be done through hands-on exercises assigned during the course. Participants can compare their completed exercises against provided solutions to determine whether they have achieved their learning goals.
