Bathymetric systems

Bathymetric systems with a focus on Multibeam and Singlebeam echosounders. It is recommended to follow Underwater Acoustics first.

Landsurveying

Covers distance, angular and range-bearing systems and computations for surface positioning and geodesy as well as height measurements with a short introduction to tides. A short introduction on statistics is given.

GNSS Operations

A comprehensive course teaching both the operational principle of Global Navigation Satellite Systems as well as the electronic basis on which they operate. All four major GNSS are described (GPS, Glonass, Beidou and Galileo) as well as their application to (hydrographic) surveying. A short introduction to relevant geodetic and statistic concepts are given.

More advanced topics such as the Least Squares Adjustment computations and satellite position computations are found in the module 'Positioning' and 'Geodetic Coordinate Reference Systems'.

Coordinate Reference Systems

Coordinate Reference Systems or the geodetic basis of any survey. Includes horizontal and vertical datum's, datum transformation and chart projections.

Bathymetry (old)

A comprehensive course comprised of both Underwater Acoustics as well as an in-depth approach to both Singlebeam and Multibeam echosounders. For these systems both their principles, installation, calibration and operation is described. Other bathymetric systems are described on a more general level including their basic measurement principles.

This course has been replaced by the following modules:

- Underwater Acoustics

- Bathymetric systems


GNSS (old)

A comprehensive course teaching both the operational principle of Global Navigation Satellite Systems as well as the geodetic and electronic basis on which they operate. All four major GNSS are described (GPS, Glonass, Beidou and Galileo) as well as their application to (hydrographic) surveying.

This course has been replaced by the following modules:

- GNSS Operations

- optional: Positioning for some more advanced subjects


Geodesy (old)

A comprehensive course giving all the necessary information to understand and apply geodetic principles to surveying in general and hydrographic surveying in particular. Topics include horizontal datums, the geoid, datum transformation, map projections in general, UTM and vessel reference systems. The course teaches both a general understanding as well as the main formula's and their application to geodetic software.

This course has been replaced by the following modules:

- Landsurvey

- Coordinate Reference Systems

- optional: Positioning for some more advanced subjects
