(Tar M-i gun) Ptarmigan. The main difference is that Cormorant systems are capable of using optical fibres that allows high speed data transfer like LAN and creates a very safe network which is really hard to be accessed by enemy. Bowman is a tactical communications system used by the British Armed Forces. Cormorant is area trunk communications network system with similar purpose as Falcon and Ptarmigan, but uses completely different technologies and ways to transfer data. The British Army has the most powerful information and communication systems available. But the main difference between them is that Bowman system was built for lighter use such as for personal radio devices for soldiers or light military vehicles as opposite to Ptarmigan which is more capable as it can transform SHF which means it is capable of more data transfer and telegraphs, but it is heavy and is installed in trucks which makes it a large piece of equipment to be used for communication. These birds choose wetter places and more luxuriant vegetation for breeding than the other two species of ptarmigan. Medium Frequency (MF) radio uses on frequencies between 300 kHz to 3000 kHz and propagates (travels) along the ground, this is called ground wave propagation. Commercial radio. They fall into three main categories: satellite ground terminals, terrestrial trunk communications systems, and combat net radio systems. affected ptarmigan behavior or movements except for possibly delaying their departure from the wintering area. That means that the purpose was the same – area network communication e.g. These seem fairly good but not perfect and at the same time maybe tune the oscillator so that all the range Mc/s number are centrally displayed. 0000007293 00000 n Falcon radio systems deliver secure voice and data over an all Internet Protocol system across multiple security domains which makes it significantly more advanced than basic radio communication systems. Two radios were principally used in the Ferret: (a) the PRC 351/352 – an intra-platoon level backpack VHF FM transceiver and (b) the VRC 353 – a vehicle-mounted VHF FM transceiver with the same frequency range as the 351/2 but greater power and potentially longer range. Clansman is the name of an integrated radio system, sometimes called a Combat Net Radio system (CNR), used by the British Armed Forces between 1976 and 2010. The antenna was a UHF parabolic reflector emitting a narrow beam of approximately 5 degrees. Ptarmigan was secure, because it used encrypted communication and only specific devices could have access to the network. It will have platforms for military headquarters of different sizes and also installed in cargo vehicles such as MAN HX 60. I started working with these systems, which for the sake of brevity I will call microwave radios, during the mid 1980s. Communication and surveillance equipment.
