2024 Technical Short Course: Multi-GNSS Precise Point Positioning and PRIDE PPP-AR

Date(s): September 10 & 12, 2024
Location: Virtual

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 will cover the application of PPP in various fields such as geodesy, seismology, aerial photogrammetry, engineering surveys, and meteorology. Participants will learn the PPP fundamentals and techniques for undifferenced ambiguity resolution, as well as hands-on experience with the PRIDE PPP-AR software. The features and capabilities of PRIDE PPP-AR will be discussed and demonstrated, with a focus on setting options for high-precision results, analyzing output, and applying the software to scientific research and engineering projects. By the end of the course, participants will have a basic understanding of high-precision multi-GNSS PPP and be equipped to use PRIDE PPP-AR software effectively. The primary tool in the workshop will be the open-source software PRIDE PPP-AR, which is available in both command-line interface for Linux systems and graphical user interface for macOS/Windows systems. The workshop will utilize the 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 some RINEX observation files, and the example data will be provided by the instructors.

Time: Two 2.5-hour sessions
Primary Audience: Researchers, students, and professionals in the field of geodesy,
GNSS, or related fields who have specific research or application needs for GNSS high-precision data
processing. They should have some basic understanding of GNSS data processing principles and a current
interest in utilizing this technology.
Secondary Audience: Individuals who are interested in geodesy or GNSS
technology and who have little to no prior experience with the principles of GNSS data processing. These
individuals may be students, hobbyists, or professionals from a variety of fields who are looking to gain a
basic understanding of GNSS data processing and its applications.

Learning Objectives

After participating in the course, attendees will gain confidence in their ability to explain how high precision GNSS works and how they can use GNSS data for geoscience applications.

After participating in the course, attendees will be able to utilize the IGS satellite products and tune the relevant parameters to achieve high-precision positions, receiver clocks, and atmosphere refractions.

After participating in the course, attendees will be able to utilize the PRIDE PPP-AR software to perform static and kinematic PPP processing.

Participant Commitment

Participants are expected to spend 5 hours in classes, and a few extra hours for self-guided practice and reinforcement of the covered concepts.

Prerequisites, Computer and Data

Participants must have knowledge in GNSS background and have basic programming skills in order to participate. It is also best to have a computer with a Linux operating system, as the programming works best on a Linux operating system.

Brief Agenda

Tentative agenda is listed below, and subject to change.

September 10, 2024 – Fundamentals of High-Precision GNSS PPP-AR
– Overview of PRIDE PPP-AR Software
September 12, 2024 – Exercise Review and Explanations
– Advanced Settings in High-Precision Processing


Assessment of the participants’ understanding of the course material will be done through hands-on exercises, which will be assigned during the course and reviewed in the subsequent class. Participants can compare their completed exercises to determine if they have achieved their learning goals.
