GENERALThe AN/ARC-210 Multimode Integrated Communications System provides a jam-resistant, two-way, voice and data communication radio for the tactical aircraft environment over the frequency range of 30 to 512 MHz. It can operate in either normal, secure or jam-resistant modes via LOS or satellite communications (SATCOM) links. The ARC-210 family of equipment is made up of several variants of the receiver-transmitter, each providing a specific combination of functionality to meet user platform requirements.

THE ARC-210 VARIANT USED IN THE CYCLONE CH-148RT-1851(C)
The Rockwell Collins "Warrior" Radios are the latest offering in the ARC-210 family of programmable Multimode Communication Systems. The 1851(C) operates in the range of 30 to 406 MHz. These radios will support the Bandwidth Efficient Advanced Modulation (BEAM) technology. BEAM technology provides data transfer rates up to 100 kbps in line of sight mode and 25 kHz channel spacing. Existing data rates over such channels without BEAM are not more than 56 kbps using MIL-STD-188-181B (dedicated SATCOM), which requires greater than 3 times more signal power than BEAM. The RT-1851A(C) offers extended frequency range operation up to 512 MHz to support interoperability between ground and airborne military forces and land based civil agencies. FM voice operation is available in 25, 12.5, and 6.25 kHz channel spacing. Continuous Tone Coded Squelch System (CTCSS) tones are selectable from all types of RT controllers (1553 bus and remote control units).
Other features:
* Software re-programmable in the field via MLVS
* MELP[1] Vocoder
* Remote Control via 1553, C-12561A Remote Control, or C-12719 Remote Control
* Network Capable (UDP and TCP/IP)
* Duty cycles up to 100% if used with the HD-1239/ARC Cooling ShroudEMBEDDED COMSEC
The ARC-210 has the follwoing communications security embedded within the design:
* Embedded TRANSEC KGV-10
* KY-58
* KYV-5 (ANDVT/LPC-10e/MELP)
* KY-100
* KG-84C
* KGV-11
* Thornton Smart Fill
* Fascinator (FED-STD-1023)FOOTNOTES:
