The Mobile Air Service (OR) , formerly Mobile Air Service (OR) or simply Air Service (OR) for short , is a mobile service in the sub-category of Mobile Air Service in accordance with the definition of the Regulations for the Radio Service (VO Funk) of the International Telecommunication Union (ITU) . This is usually a radio service between military ground radio stations and air radio stations or between military air radio stations among themselves, in which military rescue equipment radio stations are also allowed to participate. OR stands for flights outside of civil air traffic routes (off-route).

Military Mobile Aviation Service (OR)

For purely military mobile aeronautical radio (OR), including military UHF aeronautical radio , the harmonized UHF frequency band 225–400 MHz is used in NATO Europe . In the UHF band, the NATO air force mainly uses ground and air radio stations from the Have Quick and SATURN families .

In Russia and a number of the former Eastern Bloc countries, the frequency band 210–380 MHz is available. The air forces equipped with Russian aeronautical radio technology use ground and air radio stations from the R-863 family of devices. The German Air Force uses remnants of R-863M from the former NVA in DASDIPS.

Frequency ranges

This radio service is available in ITU region 1 and in particular on German territory u. a. the following frequency ranges are available.

  3. "DASDIPS" are deployable systems in the Air Force Operations Management Service (EinsFüDstLw). Mainly it concerns the ARKONA air situation display component, the remaining ground radio stations aeronautical radio service (R-863, Flugfunk Ost / original name: "Бекас P-863M") and possibly CSI (CRC / SAM interface) device. DASDIPS is mainly used for small projects (e.g. administrative assistance for the police etc.) with a focus on air situation display and interface function and serves to improve local, regional and supra-regional awareness of the situation.

  5. Footnote 2 : Frequencies up to 30,000 kHz can be used for induction radio systems. The limit values ​​of the interference-relevant parameters of induction radio systems are specified in the frequency plan or the required frequency allocation. Induction radio systems must not cause any interference with other radio systems and radio services currently and in the future to which the corresponding frequency ranges are assigned on a primary or secondary basis. Interference from these other radio systems and radio services must be accepted by induction radio systems.

Footnote 3 : In the frequency ranges 9 - 14 kHz, 72 - 112 kHz, 115 - 126 kHz, 3 500 - 3 800 kHz, 4 063 - 4 438 kHz, 5 900 - 6 525 kHz, 7 300 - 7 350 kHz, 8 195 - 8 815 kHz, 9 400 - 9 900 kHz, 11 600 - 11 650 kHz, 12 050 - 12 100 kHz, 12 330 - 13 200 kHz, 13 570 - 13 600 kHz, 13 800 - 13 870 kHz, 15 600 - 15 800 kHz, 16 460 - 17 360 kHz, 17 480 - 17 550 kHz, 18 900 - 19 020 kHz, 22 000 - 22 720 kHz, 25 070 - 25 110 kHz, 26 100 - 26 175 kHz, 28 000 - 29 700 kHz, 34.35 - 36.55 MHz, 38.45 - 39 MHz, 137 - 138 MHz, 144 - 223 MHz, 410 - 862 MHz, 1 525 - 1 535 MHz, 1 660.5 - 1 700 MHz, 2 290 - 2 300 MHz, 3 400 - 3 600 MHz, 5 150 - 5 255 MHz, 5 850 - 6 525 MHz, 14 - 14.62 GHz, 15.23 - 15.35 GHz, 17.3 - 17.7 GHz, 23 - 23.6 GHz, 31 - 31.3 GHz and 66 - 71 GHz are individual frequencies used for military purposes.
  7. Footnote D111 : The carrier frequencies 2182 kHz, 3023 kHz, 5680 kHz and 8364 kHz as well as the frequencies 121.5 MHz, 156.8 MHz and 243 MHz may, in accordance with the procedures that apply to terrestrial radio services, also be used for search and rescue operations are used when they concern manned spacecraft. This also applies to the frequencies 10003 kHz, 14993 kHz and 19993 kHz, but the emissions on each of these frequencies must be kept within the limits of ± 3 kHz of the relevant frequency.
  8. Footnote D115 : The carrier frequencies ( reference frequency ) 3023 kHz and 5680 kHz may also be used by the radio stations of the mobile maritime radio service that participate in coordinated search and rescue work.
  9. Footnote 31 : The frequency ranges above 30 MHz can also be used by radio systems with the lowest power. When selecting the frequency ranges, the increased protection requirements of safety-relevant radio applications must be guaranteed. The frequency ranges, limit values ​​of the permissible radiated power and other interference-relevant parameters of radio systems with the lowest power are specified in the frequency plan or the required frequency allocation. Low-power radio systems must not cause any interference in other radio systems and radio services currently and in the future to which the corresponding frequency ranges are assigned on a primary or secondary basis. Interference from these other radio systems and radio services must be accepted by radio systems with the lowest power.
