Station

One or more transmitters or receivers or a combination of transmitters and receivers, including the accessory equipment, necessary at one location for carrying on a radio communication service. Each station shall be classified by the service in which it operates permanently or temporarily.

1

Fixed service (Fixed station)

A service of radio-communication between specific fixed points

Types:
Aeronautical fixed service (aeronautical fixed station) - A fixed service intended for the transmission of information relating to air navigation, preparation for and safety of flight

2

Mobile service

A service of radiocommunication between mobile and land stations, or between mobile stations

Stations:
1. Land Station - not intended to be used while in motion
2. Mobile station - intended to be used while in motion or during halts at unspecified points

3

Aeronautical mobile service

A mobile service between aeronautical stations and aircraft stations, or between aircraft stations, in which survival craft stations may also participate

Station:
Aeronautical station - A land station in the aeronautical mobile service. In certain instances an aeronautical station may be placed on board an aircraft.

4

Maritime mobile service

A mobile service between coast stations and ship stations, or between ship stations, in which survival craft stations may also participate

Types:
Port operations service - A maritime mobile service in or near port, between coast stations and ship stations or between ship stations, in which messages are restricted to those relating to the movement and the safety of ships and, in emergency, to the safety of persons

Stations:
1. Coast Station - land station
2. Ship Station - Mobile Station
3. On-board communication station - A low-powered mobile station in the maritime in the maritime mobile service intended for use for internal communications on board

5

Ship's emergency transmitter

A ship's transmitter to be used exclusively on a distress frequency for distress, urgency or safety purposes

6

Broadcasting service

A radio communication service in which the transmissions are intended for direct reception by the general public. This service may include sound transmissions, television transmissions or other types of transmission

7

Survival Craft station

A mobile station in the maritime or aeronautical mobile service intended solely for survival purposes and located on any lifeboat, lifecraft or other survival equipment.

8

Land mobile service

A mobile service between base stations and land mobile stations, or between land mobile stations.

Stations:
1. Base station - a land station carrying on a service with land mobile stations
2. Land Mobile Station - mobile station capable of service movement within the geographical limits of a country or continent

9

Radiodetermination

The determination of position or the obtaining of information relating to position, by means of the propagation properties of radio waves

Radiodetermination service - radiodetermination station

10

Radionavigation Service

A radiodetermination service involving the use of radionavigation

Stations:
1. Radionavigation Land Station
2. Radionavigation Mobile Station

Types:
1. Aeronautical
2. Maritime

11

Radiolocation

Radiodetermination used for purposes other than those of radionavigation

Radiolocation service - Radiolocation land and mobile station

12

Radar

A radiodetermination system based on the comparison of reference signals with radio signals reflected from the position to be determined

13

Radio Direction Finding

Radiodetermination using the reception of radio waves for the purpose of determining the direction of a station or object

Radio Direction-Finding Station - A radiodetermination station using radio direction finding

14

Radiobeacon station

A station in the radionavigation service the emissions of which are intended to enable a mobile station to determine its bearing or direction in relation to the radiobeacon station.

15

Space station

A station location on an object which is beyond, is intended to go beyong, or has been beyond, the major portion of the Earth's atmosphere

16

Earth station

A station located either on the Earth's surface or withing the major portion of the Earth's atmosphere intended for communication

17

Space and Terrestrial Radiocommunication

Space radiocommunication - any radiocommunication involving the use of one or more space stations or the use of one or more passive satellites or other objects in space

Terrestrial radiocommunication (terrestrial station) - any radiocommunication other than space radiocommunication or radio astronomy

18

Radio Astronomy

Astronomy based on the reception of radiowaves of cosmic origin

Radio astronomy service - a service involving the use of radio astronomy

19

Meteorological Aids Service

A radiocommunication service used for meteorological, including, hydrological, observations and exploration

21

Radiosonde

An automatic radio transmitter in the meteorological aids service usually carried on an aircraft, free balloon, kite or parachute, and which transmits meteorological data

22

Space System

Any group of co-operating earth and/or space stations employing space radiocommunication for specific purposes

23

Satellite System

A space system using one or more artificial earth satellites

24

Satellite Network

A satellite system or a part of a satellite system consisting of only one satellite and the co-operating earth stations

25

Satellite Link

A radio link between a transmitting earth station and a receiving earth station through one satellite. A satellite link comprises one up-path and one down-path

26

Multi-satellite Link

A radio link between a transmitting earth station and a receiving earth station through two or more satellites without any intermediate earth station

A multi-satellite link comprises one up-path, one or more satellite-to-satellite paths and one down-path

27

Fixed Satellite service

A radiocommunication service:

1. between earth stations at specified fixed points when one or more satellites are used; in some cases this service includes satellite-to-satellite links, which may also be effected in the inter-satellite service;
2. for connection between one or more earth stations at specified fixed points and satellites used for a service other than the fixed-satellite service

28

Individual and Community Reception

Individual reception - the reception of emissions from a space station in the broadcasting-satellite service by simple domestic installations and in particular those possessing small antennae

Community reception - The reception of emission from a space station in the broadcasting-satellite service by receiving equipment, which in some cases may be complex and have antennae larger than those used for individual reception, and intended for use by a group of the general public at one location; or through a distribution system covering a limited area

29

space research service

A radiocommunication service in which spacecraft or other objects in space are used for scientific or technological research purposes

30

Space Operation Service
