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.

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

One project is quot Bus Tram Bunn 2002 quot , which envisages further development of the public transport network and construction of sections of the light rail transport system.

3. Little LEO

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

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.

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.

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.

(b) The creation of space debris in orbits that repeatedly intersect orbital paths used by space systems should be avoided

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 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.

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

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

(e) Space systems and space system elements, including launch vehicle stages, in orbits with perigee altitude below 2,000 km should remain in orbit for no longer than 25 years after completion of the operational mission.

The Indonesian Orbital Debris Monitoring System is now under development.

Celestri GSO used nine satellites to provide global coverage.

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.

The post operational orbital lifetime of space systems and space system elements, including launch vehicle stages, in orbits with perigee altitude below 2,000 km should be limited to 25 years.

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.

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.

(f) Adopt links or develop bridges to international standard concepts and classifications in economic environmental statistics to facilitate the integration and interface of energy statistics with other statistical systems

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