The Global Telecommunication System (GTS) consists of an integrated network of point-to-point circuits, and multi-point circuits which interconnect meteorological telecommunication centres.
The ... circuits of the GTS are composed of a combination of terrestrial and satellite telecommunication
- point-to-point circuits,
- point-to-multi-point circuits for data distribution,
- multi-point-to-point circuits for data collection,
- as well as data-communication network services.
