Content outline:

  • Global Navigation Satellite Systems (GNSS). This part presents the fundamentals of GNSS and describes the GPS, GLONASS, GALILE and BEIDOU system. The module introduce the use of RTKLIB, a free software for GNSS post-processing.
  • Statistical tools details the statistical analysis of least square solution, with application to hydrographic problems.
  • A detailed presentation of Inertial Navigation Systems (INS) comprises principles, practical alignement of INS, the problem of heave estimation, and INS/GNSS hybrid systems.
  • Subsea positioning presents the principle of acoustic positioning , including Short baselines, Ultra Short base lines, Long base lines.


The main learning outcomes of POS are:

  1. To operate a hybrid positioning system and to perform positioning quality control. To differentiate the main GNSS modes and interpret quality factor in relation to sources of errors.
  2. To describe the principle of acoustic positioning system, to perform LBL and USBL calibration.
  3. Understand the concepts of inertial navigation systems, perform the static and dynamic alignment of an INS, describe heave measurement principle and sources of errors.
