REFERENCE FRAME IN PRACTISE SEMINAR AND BELS+ TRAINING

20 - 21 APRIL 2019 at Intercontinental Landmark 72

Room Hanoi 1, 5th floor

THANK YOU TO THE SPONSOR:

The Technical Seminar on Reference Frames in Practice was held in Hanoi on 20-21 April 2019. The main focus was on reference frames in general with a specific focus on UN initiatives and reference frame examples in the Asia-Pacific region.  A BELS+ Training was also completed on the second day of the seminar.  The Seminar was organized by FIG Commission 5, in conjunction with the International Association of Geodesy (IAG), the United Nations International Committee on GNSS (UN ICG), UN Global Geospatial Information Management – Asia Pacific (UN-GGIM-AP), BELS+, and the Vietnam Association of Geodesy, Cartography, and Remote Sensing (VGCR). The seminar was held in the InterContinental Landmark 72 Hotel in conjunction with the FIG Working Week 2019 at the Vietnam National Convention Center.

There were 43 participants including presenters from around the world representing 20 different countries.  Countries represented included Australia, Austria, Bangladesh, Belgium, Fiji, Germany, Italy, Japan, Mexico, New Zealand, Pakistan, Philippines, Qatar, Russian Federation, Singapore, Spain, Uganda, United States, and Viet Nam.  Attendees represented a mix of academic, government, and commercial institutions.

Dan Roman, Chair of FIG Commission 5

SUNDAY 21 APRIL

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).
