205. The future of terrestrial based radio navigation systems, in view of the development of satellite based systems, is unclear.

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.

Studies on a worldwide radio navigation system are being conducted within the United Nations system.

Lastly, in the field of telecommunications, France is a participant in the Global Navigation Satellite System (GNSS) programmes for air navigation.

The system was a double satellite hop using the American Telephone amp Telegraph (AT amp T), INTELSAT and NASA Satcom satellites.

(d) Use of the global navigation satellite system (the Russian system GLONASS and the American Global Positioning System (GPS))

The system, based on very high frequency radio, will enable users to ascertain the name, position, course, speed, draught and cargo of every ship of more than 300 gross tons sailing in the Baltic Sea.

Check secondary guidance.

IMO, in close cooperation with BR and the International Hydrographic Bureau of the International Hydrographic Organization, has finalized a study on the use of electronic chart display and information systems on board ships, including means of updating electronic navigational charts, which will be broadcast through the Inmarsat Enhanced Group Call and SafetyNET systems.

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.

It was also providing services and products for all phases of the life cycle of the space system, including system engineering and mission development for space systems development and production of small spacecraft bus vehicles space electronics and power management systems high performance data storage systems and electrical ground support and ground control equipment.

The satellite navigation systems will make it possible to provide the services needed for the navigation of civil aircraft.

(c) Developing the means of communication and of computer science, including new mobile paid radio telephones and electronic cards for them, large ground based antenna systems for communications and television broadcasting and river navigation systems

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

The ITU R Study Group 8 (mobile, radio determination, amateur and related satellite services) continues to examine various aspects of satellite uses in GMDSS, including the characteristics of satellite emergency position indicating radiobeacon (EPIRB) systems, and studies on technical and operational characteristics of satellite systems participating in GMDSS and GNSS.

Cooperative programme with NASA to study the interaction between the system (satellite conductive tether deployer in the space shuttle s cargo bay) and the Earth s ionosphere.

The alarm system is battery and circuitpowered.

On 11 January 1995, the cosmonauts carried out checks of the Kurs and radioelectronic docking system mounted on a connecting section of the station.

Following adoption of the initial set of standards and recommended practices for GNSS, ICAO is developing similar standards and recommended practices for ground based regional augmentation systems and for new GNSS elements such as the modernized Global Positioning System of the United States, the Global Navigation Satellite System (GLONASS) of the Russian Federation and the European Galileo system.

ICAO is continuing to consider the legal aspects of the implementation of CNS ATM systems, which principally relate to the legal framework for the Global Navigation Satellite System (GNSS).
