INTERNATIONAL GLONASS SERVICE - PILOT PROJECT

The International GLONASS Service - Pilot Project (IGLOS-PP) is a pilot service of the International GPS Service (IGS) to track and analyze data from the Russian GLONASS satellite constellation. The primary products of the service are dual-frequency observations from the global tracking network and precise orbits computed for each satellite. These are made available to support and encourage other applications and studies. In particular, the products from the Service facilitate the use of combined GLONASS and GPS observations for scientific and engineering applications, and allow users to experiment with the combined systems as a prototype Global Navigation Satellite System. The pilot service will operate for a period of up to four years, from 2000-2003.

Goals and Objectives

  1. Establish and maintain a global GLONASS tracking network
    • Collocate dual-frequency, combined GPS/GLONASS receivers with dual-frequency GPS receivers or upgrade existing dual-frequency GPS receivers to dual-frequency, combined GPS/GLONASS receivers at existing IGS sites and at new sites
    • Apply International GPS Service (IGS) network operations standards
    • Calibrate and evaluate combined GPS/GLONASS receivers and antennas
  2. Produce precise (10-cm level) orbits, satellite clock estimates, and station coordinates
    • Evaluate microwave-derived orbits using SLR observations and orbits
    • Incorporate SLR observations in routine orbit processing
    • Obtain initial operational capability of 20-50 cm orbits at Analysis Centers
    • Receive independent orbit/clock/station solutions from Analysis Centers within three weeks of observations
  3. Monitor and assess GLONASS system performance
  4. Investigate the use of GLONASS to improve Earth Orientation Parameters
  5. Improve atmospheric products of the IGS
  6. Fully integrate GLONASS into IGS products, operations and programs.

Organizational Structure

The Pilot Service will utilize the existing infrastructure of the IGS as much as possible without disrupting activities supporting GPS data collection and processing. It will take advantage of the operational experience gained from the International GLONASS Experiment (IGEX-98) carried out in 1998-99. A Call for Participation will be issued to enlist the participation of current IGS network stations, analysis centers, and data centers, as well as to solicit the participation of new stations and analysis centers. The IGS Central Bureau will be asked to affirm acceptance of the increased responsibility resulting from the inclusion of the pilot service within the IGS. The pilot service will include SLR stations, GLONASS stations, and combined GPS/GLONASS stations that meet IGS network requirements and additional GLONASS-specific requirements.

An IGLOS Pilot Project Committee is responsible for establishing and managing the service during the pilot period. The members are:

  • Vladimir Glotov, Mission Control Centre, Russian Space Agency
  • Ramesh Govind, Australian Surveying and Land Information Group
  • Werner Gurtner, University of Berne, Astronomical Institute, ILRS Liaison
  • Arne Jungstand, EC Joint Research Centre, Space Applications Institute, and DLR
  • Angelyn Moore, IGS Central Bureau
  • Ruth Neilan, IGS Central Bureau, Director (ex officio)
  • Carey Noll, NASA Goddard Space Flight Center, Data Center Coordinator
  • James Slater, National Imagery and Mapping Agency, Chair
  • Tim Springer, University of Berne, IGS Analysis Center Coordinator (ex officio)
  • Robert Weber, University of Technology, Vienna, GLONASS Analysis Center Coordinator
  • Pascal Willis, Institut Geographique National.

The IGLOS Pilot Project Committee will review and approve proposals for establishment of new stations, analysis centers and data centers, taking appropriate actions as necessary. The description and responsibilities of these fundamental IGS components are located in the IGS Terms of Reference at . Technical specifications for stations, analysis centers and data centers are included in the Call for Participation. The Committee will develop operational guidelines for incorporating the GLONASS operations into the IGS. Liaisons are maintained with the International Laser Ranging Service, the International Association of Geodesy, and the GLONASS Coordination Scientific Information Center of the Russian Federation Ministry of Defense as appropriate.
