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

(b) Development of a GPS overlay, a system that recovers the accuracy degradation of the GPS system by using GPS signals transmitted by a geostationary satellite

GTOS is envisaged as one of a number of global observing systems which will be complementary to each other and mutually supportive.

(b) Greater participation and coordination for the Integrated Global Observing Strategy being pursued in the development of the global observing systems (the Global Climate Observing System (GCOS), the Global Terrestrial Observing System (GTOS) and the Global Ocean Observing System (GOOS).

These programmes include the Global Climate Observing System (GCOS), and the Global Ocean Observing System (GOOS).

These programmes include the Global Climate Observing System (GCOS) and the Global Ocean Observation System (GOOS).

The rapporteur also liaises with the WMO Commission for Basic Systems Working Group on Satellites, GOSSP of the Global Observing Systems (GCOS, GOOS, GTOS) and with IOC.

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.

WWW has three readily identifiable components the global observing system (GOS) the global telecommunication system and the global data processing system.

(c) Development of a Global Time System (GTS)

The United States strongly supports a global warning system, conducted under the aegis of the Global Earth Observation System of Systems (GEOSS).

Inter agency efforts could be further strengthened to emphasize the important role of space based observing systems as a part of the jointly sponsored global observing systems (GCOS, GTOS, GOOS), with the participation of space agencies through the Committee on Earth Observation Satellites

In turn, WHYCOS would contribute data to the World Weather Watch system, GCOS and GTOS.

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.

1. Expresses appreciation of the work carried out by the relevant intergovernmental organizations, particularly the development of such observational programmes as the Global Climate Observing System (GCOS), the Global Ocean Observing System (GOOS) and the Global Terrestrial Observing System (GTOS)

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

The system will be connected to the Global Sea Level Observing System.48

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.

In 1996, the Space Observation Panel was asked to broaden its focus by including GTOS and GOOS space requirements and has been renamed as Global Observing Systems Space Panel.

We view this system as an important stage in the establishment of a global disaster early warning system.

While studies are under way to apply space technology to establish safety and early warning systems, such as the Global Maritime Distress and Safety System (GMDSS) and early warning systems for the reduction of natural disasters.

The proposed Environment Watch system and the Global Earth Observation System of Systems are mutually supportive and could address this need, and Governments, the scientific community and partners could be called on to play an active role in their incremental development

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