Global Navigation Satellite Systems KGG306


Global Navigation Satellite Systems (GNSS) enable autonomous global positioning using signals broadcast from various satellite constellations. With an ability to achieve accuracies ranging from metres to millimetres, GNSS provides positioning capability that underpins a host of scientific, commercial, civilian, and military applications.

The unit commences with an introduction to GNSS, then a review of coordinate systems and transformations before progressing into the examination of GNSS signals, biases and a range of positioning and processing techniques (e.g., baseline processing, precise point positioning and Real-Time (RTK) correction). Applications of GNSS technology are also reviewed in the unit.

One of the key objectives of this unit is to provide students with high-level skills in the collection, processing, and presentation of GNSS data. In the practical component, students will gain experience using GNSS equipment to achieve various levels of coordinate precision and develop skills in GNSS data collection techniques suitable for mapping, surveying, and scientific applications.

Students enrolling in this unit are expected to have a good understanding of coordinates and mapping and be comfortable working with basic numerical (coordinate) data handling and analysis.

Please check that your computer meets the minimum System Requirements if you are attending via Distance/Off-Campus.

Units are offered in attending mode unless otherwise indicated (that is attendance is required at the campus identified). A unit identified as offered by distance, that is there is no requirement for attendance, is identified with a nominal enrolment campus. A unit offered to both attending students and by distance from the same campus is identified as having both modes of study.
