service for the purpose of radiolocation", where radiolocation is defined as: "radiodetermination used for purposes other than those of radionavigation." Classification This radiocommunication service is classified in accordance with ITU Radio Regulations (article 1) as follows: Radiodetermination service (article 1.40) Radiolocation service (article 1.48) Radiolocation-satellite service (article 1.49) The radiolocation service distinguishes basically Radiolocation mobile station land-mobile, air-mobile, sea-mobile (article 1.89) Radiolocation land station (article 1.90) Examples Satellites Radiolocation-satellite service (short: RLSS) is – according to Article 1.49 of the International Telecommunication Union´s (ITU) Radio Regulations (RR) – defined as «A radiodetermination-satellite service used for the purpose of radiolocation. This (radiocommunication) service may also include the feeder links necessary for its operation.» The radiolocation-satellite service distinguishes basically Earth radio stations Feeder links and Space radio stations For example military radar sensors in earth satellites operate in the radiolocation-satellite service n this service. Examples of radio stations in the radiolocation-satellite service Frequency allocation The allocation of radio frequencies is provided according to Article 5 of the ITU Radio Regulations (edition 2012). In order to improve harmonisation in spectrum utilisation, the majority of service-allocations stipulated in this document were incorporated in national Tables of Frequency Allocations and Utilisations which is within the responsibility of the appropriate national administration. The allocation might be primary, secondary, exclusive, and shared. Example of frequency allocation Stations Land station A radiolocation land station is – according to article 1.90 of the International Telecommunication Union's (ITU) ITU Radio Regulations (RR) – defined as "a radio station in radiolocation service not intended to be used while in motion." Each radiolocation station shall be classified by the radiocommunication service in which it operates permanently or temporarily. In accordance with ITU Radio Regulations (article 1) this type of radio station might be classified as follows: Radiodetermination station (article 1.86) of the radiodetermination service (article 1.40 ) Radionavigation mobile station (article 1.87) of the radionavigation service (article 1.42) Radionavigation land station (article 1.88) of the radionavigation service Radiolocation mobile station (article 1.89) of the radiolocation service (article 1.48) Radiolocation land station Selection radiolocation land stations Mobile station Radiolocation mobile station is – according to article 1.89 of the International Telecommunication Union´s (ITU) ITU Radio Regulations (RR) – defined as "A radio station in radiolocation service intended to be used while in motion or during halts at unspecified points." Each radiolocation station shall be classified by the radiocommunication service in which it operates
