# GEOM 3050 - Introduction to Geodetic Positioning

## Geomatics Part-time Studies Course

### School of Construction and the Environment

BCIT is planning for a substantial return to on-campus activity for the fall 2021 term as informed by BC Public Health Officer guidelines. Refer to each course listing for details.

# Course Details

This course covers three aspects of geodesy including geometrical geodesy, physical geodesy, and satellite geodesy. Topics will include the fundamentals of geodesy, the shape and size of the Earth and their impact on the standard surveying field procedures and computations. Also includes physical and mathematical modelling of the real Earth, ellipsoid of revolution and ellipsoidal geometry, problem and definitions of horizontal and vertical datums, deflection of vertical, convergence of meridians, height systems, various coordinate systems and their transformations, and map projection systems. It concludes with introduction to satellite geodesy and the necessary concepts related to use of survey grade Global Navigation Satellite System (GNSS) receivers to conduct different modes of positioning and data processing. It also reviews the errors and biases involved in GNSS surveys and how to cancel and/or mitigate them in different GNSS applications. Precise point positioning, baseline, and network processing using both collected and freely available GNSS data from reference station networks in North America are also discussed.
