1、T/R 21-10 E Page 1 I The European Conference of Postal and Telecommunications Administrations, Recommendation T/R 21-10 E (Bonn 1993) TRAK-SAT LAND MOBILE-SATELLITE SERVICE TERMINALS IN EUROPE relating to type approval, marking and free circulation and use of TRAK-SAT terminais in CEPT countries Rec
2、ommendation proposed by the Working Group “Radio Regulatory” (RR) Text of the Recommendation adopted by the “European Radiocommunications Committee” (ERC): INTRODUCTION TRAK-SAT Communications Limited is aregistered company in the United Kingdom which has been formed to establish a Land Mobile Satel
3、lite Service (LMSS) in Region 1 of the ITU. The TRAK-SAT satellite network provides low bit rate 2-way data services and operates in the 131.6 GHz frequency bands in Region 1 (Europe, Middle East and Africa). This satellite system is optimised for use by closed user groups. TRAK-SAT service has the
4、possibility to use the satel- lite infrastructure of Inmarsat or the Russian VOLNA satellite system. European Telecommunication Standards Insti- tute (ETSI) is preparing to develop a European Standard (ETS) for all mobile satellite terminals in the frequency bands 131.6l2.5 GHz. Therefore, it is pre
5、ferable to have an interim Recommendation relating to type approval and free cir- culation and the use of TRAK-SAT terminals in the CEPT member countries. After adoption of an ETS and imple- mentation by the CEPT Administrations the type approval and marking procedures of the Recommendation T/R 7 1-
6、03 E are applicable. O considering a) that TRAK-SAT service as a Land Mobile Satellite Service (LMSS) will be introduced into Europe, the Middle East and Africa, b) that for the LMSS the 131.6 GHz frequency bands have been allocated in accordance with article 8, number 726B, of the Radio Regulations
7、 (RR), c) that frequencies from the bands 1536.15-1536.65 MHz and 1637.65-1638.15 MHz are used by the TRAK-SAT system, d) that TRAK-SAT service provides interconnection with the public telecommunications network for closed user group communications and is limited to non speech low bit rate 2-way dat
8、a transmission, only, e) that it will be desirable for the CEPT member countries to have common regulations at their disposal in order to control the type approval, marking, free circulation and the use of TRAK-SAT terminals in Europe, f, that TRAK-SAT terminals will be required to meet the standard
9、s of technical performance as described in Canadian Astronautics Ltd. specification CAL-TS-0494- 10005, 24 September 1992, pending the development of a relevant ETS, O recommends 1. that CEPT member Administrations will accept type testing as required by the Government of Canada, Department of Commu
10、nications on TRAK-SAT terminals, as described in Document No. GL-22 Technical Acceptance of Mobile Earth Terminals and will accept this as a basis for interim type approval-until end 1993, 2. that CEPT member Administrations shall not require an individual licence for non-residents for the TRAK-SAT
11、terminals, 3. that CEPT member Administrations shall permit the free circulation and use of TRAK-SAT terminals provided that pending the developing of an ETS by ETSI the TRAK-SAT terminal has been type approved in accordance with Recommends 1 and bearing a mark in conformity with the conditions set
12、out in Annex 1 of this Recommendation.
