About IVS

Committees: VGOS Technical Committee

Purpose The primary function of the VGOS Technical Committee (formerly VLBI2010 Committee) is to promote and guide research into the improvement of the "technique" of geodetic VLBI. The committee takes an integrated view of VLBI and evaluates the effectiveness of proposed system changes based on the degree to which they improve IVSís final products. In addition, the committee takes responsibility for encouraging the implementation of the recommendations of WG3.

The VGOS Technical Committee typically gains understanding of the effectiveness of new hardware, software, strategies, etc through the use of combinations of the following approaches:

  • Analytic studies
  • Simulations
  • Prototyping
  • R&D experiments
  • Re-analysis or interpretation of previous campaigns or global data sets
  • Inter-technique co-location studies

Over time, the VGOS Technical Committee will develop and maintain outputs, such as

  • A list of all known error sources (along with their size, effect, and characterization)
  • A list of strategies for reducing all known error sources
  • A prioritized list of actions required to improve the technique
  • A list of all standard interfaces needed to achieve system-wide compatibility
  • Standardized specifications for each system component
  • Publicly available software, e.g. to carry out simulations

Ongoing activities will include

  • The establishment and maintenance of a memo series
  • Monthly telecons (with splinter telecons as required)
  • Face-to-face meetings (scheduled at convenient times such as the IVS GM)
