20 - 21 APRIL 2019 at Intercontinental Landmark 72

Two combined technical seminars will be held. The Reference Frames in Practive (RFIP) seminar will be held the first day, while the Building European Links toward South East Asia in the field of EGNSS (BELS+) seminar will be on the second day. The RFIP will provide the international context for many global and Asia-Pacific regional geodetic initiatives as well as overviews of reference frames with multiple national case studies to highlight how different countries are implementing these global initiatives. The BELS+ seminar will provide Training and Awareness to surveyors through the South East Asia region on the use of GNSS tools and data, including a discussion focused on activities at the Research Centre in Vietnam.


The fee for the two day event is 120 EUR.

BELS+ European GNSS Solutions for Surveyors


The BELS+ Training day is a course on Global Navigation Satellite Systems (GNSS) data processing which focusses on the suverying domain. The training covers in detail in the study of the concepts and techniques used in the high-accuracy positioning by means of GNSS. The theoretical foundations for Standard and Precise Point Positioning (SPP, PPP) are presented, focusing in the instrumental use of the concepts and techniques of GNSS navigation. In particular, the different terms involved in modelling the code pseudoranges and carrier-phase measurments (relativistic effects, atmospheric propagation effects at troposphere/ionosphere, instrumental delays, clock synchronism, etc.). The processing algorithms are discussed in detail and implemented through guided exercises in the laboratory session based on the ESA/UPC GNSS Laboratory tool suite (gLAB), where the impact of the modelling accuracy is assessed in the positionin domain.

Also during the training course, participants can practice with NAVISIM – a Softwared Defined Radio GNSS signal generator – which can be used in laboratory for testing and validating the operation of GNSS receivers in different harsh real-world scenarios, as well as for training GNSS users (surveyors).
