Electromagnetic compatibility and Radio spectrum Matters (ERM); Meteorological Aids (Met Aids); Radiosondes to be used in the 1 668,4 MHz to 1 690 MHz frequency range; Part 1: Technical characteristics and test methods

Scope

The present document applies to digitally modulated Radiosonde transmitters and whole units in the range from 1 668,4 MHz to 1 690 MHz. Because the World Radio Conference WRC-2003, allocated the Mobile Satellite Service (MSS) in the band from 1 670 MHz to 1 675 MHz, and the sub band from 1 683 MHz to 1 690 MHz is used for meteorological satellite, it is encouraged to consolidate the Radiosondes in the sub band from 1 675 MHz to 1 683 MHz. The present document shall not be applied to the widely used analogue FM Radiosonde transmitter. The present document does not necessarily include all the characteristics, which may be required by a user, nor does it necessarily represent the optimum performance achievable. It is a product family standard, which may be completely or partially superseded by specific standards covering specific applications.
