SNG/OB stations are fixed stations for voice and data communication with satellite systems for journalistic purposes.
The radio frequencies allocated to SNG/OB applications in the General Act on Radio Frequency Utilisation Plan may be used for this purpose. These transmitting frequencies can only be used in applications designated for the earth – space direction.
The Agency begins the procedure of allocating radio frequencies after receiving an application, then issues a decision on allocating radio frequencies (DARF), with which use is permitted on a particular frequency channel. Also specified are: modulation, fixed location, transmission direction (azimuth and elevation), as well as minimum requirements regarding the technical parameters.
The terrestrials stations with appropriate parameters can also operate without a decision on the allocation of radio frequencies.
