GLONASS Global Orbiting Navigation Satellite System (Russian Federation)

While the Global Positioning System (GPS) and the Global Orbiting Navigation Satellite System (GLONASS) are regarded as candidates, consideration is also being given to a post GPS GLONASS system.

Global navigation satellite systems (GNSS), such as the Global Positioning System (GPS) of the United States and the Global Navigation Satellite System (GLONASS) of the Russian Federation, provide accurate position, velocity and time information that is readily accessible at ground level to anyone with a receiver.

A total of 25 spacecraft from the Cosmos series are now in orbit as part of the GLONASS system.

As the operational availability of the Global Positioning System (GPS) and the Global Navigation Satellite System (GLONASS) is limited, consideration is being given to a post GPS GLONASS system.

The Government of the Russian Federation confirmed a similar offer for GLONASS, consisting of 24 operational navigation satellites.

GPS and GLONASS, which are candidate systems, are expected to be available for consideration and acceptance in the period 1995 1996.

There are currently 13 spacecraft from the Cosmos series in orbit as part of GLONASS.

3. Little LEO

GPS and GLONASS, which had been offered by Governments as operational candidate systems, were evaluated, recognized and accepted in 1996.

In particular, the civil navigation community in Europe is looking at them in the context of a future Global Navigation Satellite System.

Furthermore, ICAO is developing provisions for ground and satellite based augmentation systems for GPS GLONASS to improve their overall availability, integrity and accuracy for aeronautical applications.

A first step in the programme was the development of the European geostationary navigation overlay service, a European regional augmentation to GPS and the Global Orbiting Navigation Satellite System (GLONASS) of the Russian Federation.

The interference caused by the Global Orbiting Navigation Satellite System (GLONASS) at 1612 MHz had recently been resolved.

Such systems include those for guidance and control, sounding rocket mechanism and structures, development and testing of propellant raw materials and solid propellant, space vehicle payload and telemetry technology, data communication and low Earth orbit tracking technology.

The Celestri system would comprise the Celestri LEO system and two other systems also developed by Motorola the Millennium and the M Star systems.

Currently neither GPS nor GLONASS met civil navigation requirements, and suffered from a lack of civilian control. G. Wrap up session

As the operational availability of GPS has been guaranteed by the United States only until 2005 and GLONASS by the Russian Federation until 2010, IMO is considering the need and seeking the means to develop plans for a post GPS GLONASS system, internationally controlled civil GNSS in cooperation with ICAO and other user organizations.

The year 1997 saw the continued operation of the Global Orbiting Navigation Satellite System (GLONASS), used for navigation by civil aircraft and naval vessels and also by other sectors of industry.

The Celestri LEO system was designed to enable frequency sharing of the Ka band spectrum with GSO and other LEO systems by using satellite diversity.

The propulsion system, batteries and the attitude and orbit control subsystem should be monitored in that context.

A. Space transportation and orbital infrastructure systems

The current expansion of satellite systems affected both those based on geostationary satellites and those based on constellations of LEO and MEO satellites.

One is the database subsystem that accumulates orbital data of space objects, and the other is the subsystem that analyses these orbital data.

Atmospheric drag, distribution of ballistic coefficients and orbit eccentricity are taken into account in the orbit propagation.

The orbital network of the space communications, television transmission and navigation system comprises the Gorizont (communications and television), Ekspress (communications and television), Ekran M (television) and Nadezhda (navigation and rescue) spacecraft and the GLONASS system.

As the operational availability of GPS has been guaranteed by the United States only until 2005 and the operational availability of GLONASS has been guaranteed by the Russian Federation only until 2010, IMO is considering the need and seeking the means to develop plans for a post GPS GLONASS system, on the basis of internationally controlled civil GNSS in cooperation with ICAO and other user organizations.

It is reported that some that already have an EMS in place are currently bringing these into line with ISO 14001.

The re entry time of each object is computed by the orbit analysis subsystem and registered in the database subsystem.

The M Star system had 72 operational LEO satellites in 12 inclined orbital planes.

The influence of low Earth orbit satellite communication systems on the growth of debris in orbit has been investigated in a series of studies.R. Walker, R. Crowther, G. G. Swinerd, The Long Term Implications of Operating Satellite Constellations in the Low Earth Orbit Debris Environment, Advances in Space Research, vol. 19, No. 2, p. 355 358, 1997.
