2022 Short Course: Multi-GNSS Precise Point Positioning and PRIDE PPP-AR

Dates: September 19 & 23, 2022
Times:  7:00-9:30am MDT (13:00-15:30 UTC)
Venue: Virtual
Applications Open: June 21, 2022

Course Description

This course will cover the theory and application of PRIDE PPP-AR v2.2 in multi-GNSS integration for undifferenced data processing. Fundamentals of PPP and methods to achieve undifferenced ambiguity resolution will be introduced in detail and experimented with using the PRIDE PPP-AR software. New features of PRIDE PPP-AR v2.2 will be demonstrated, including command-line operation, multi-day data processing, RTS service, and GUI tools.

Learning Goals

Participants who complete this course will gain an understanding of the theory of Global Navigation Satellite System (GNSS) precise point positioning (PPP), undifferenced ambiguity resolution, phase and code biases, multi-GNSS (GPS/GLONASS/BDS/Galileo/QZSS) integration, satellite attitude corrections, troposphere retrieval, higher-order ionospheric corrections, and super-high-rate (50 Hz) data processing. The participants will also learn how to use the PRIDE PPP-AR software to accomplish PPP and PPP ambiguity resolution (PPP-AR) at static and kinematic stations for tectonics, seismology, aerial photogrammetry, and airborne/shipborne gravimetry.

Application Process

Participants should apply through the link to the right to participate, as we expect demand to exceed capacity. Decisions will be made on responses to prompts in the application. Priority will be given to applicants from UNAVCO member institutions, and who need the training to conduct research in the next year. (Check to see if your institution is a member of the UNAVCO consortium.) 

Review of applications begins on June 29, 2022; applicants will be notified of their status on August 19, 2022.
