Fundamentals of Single-Base Real-Time GNSS Positioning

This online engineering CPD course examines the principles, procedures, and surveying practices associated with classical single-based real-time (RT) GNSS positioning.
This course focuses on RTK equipment configurations, including base and rover setups, wireless communication links, and the GNSS error budget. It describes the technical processes of carrier phase differencing and ambiguity resolution used to achieve centimeter-level relative accuracy. Furthermore, this course examines environmental factors such as multipath, atmospheric refraction, and space weather conditions (geomagnetic and solar radiation storms) that impact signal integrity.
In addition, this course explores the core of real-world geodetic positioning, field procedures, site localizations, and accuracy assessments. It also explains how RT GNSS technology works, how to select the right accuracy classes (RT1 through RT4), and how to align field methods with performance goals, all rooted in real-world surveying and engineering applications. This course includes several metrics, and easy-to-understand Best Methods guidelines based on experience and commonly accepted practices in the geospatial and GNSS industries.
This 6 CPD online course is applicable to civil engineers, surveyors, as well as other technical professionals who are interested in learning more about single-based real-time GNSS positioning.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding the principles of classical single-base RTK positioning, including the roles of the base station, rover, and wireless data links
- Identifying the components of the GPS error budget and explaining how double differencing eliminates satellite and receiver clock errors
- Analyzing the impact of atmospheric delays and space weather (geomagnetic storms, solar radiation, and radio blackouts) on survey precision
- Describing field procedures for site localizations, including the requirements for constraining multiple horizontal and vertical passive monuments
- Distinguishing between the four RT Accuracy Classes based on baseline length, PDOP, RMS, and required redundancy
- Recognizing the "Best Methods" for RT positioning, focusing on equipment adjustment, checking known points, and managing metadata
