+ | ====== Aeronautical ground stations ====== | ||
+ | Radio communication between aircraft and ground has been used for various purposes: for communication with the airfield regarding landing and weather information, | ||
+ | In the first years, radio transmissions were only used to transmit messages from an aircraft (eg. results of an observer mission or informations to direct the own artillery fire " | ||
+ | |||
+ | If information had to be transmitted from the ground to the pilot, signs from fabric laid on the ground were used to signal to the pilots. | ||
+ | |||
+ | Beginning in 1930, radio equipment made it's way on board aircraft; in the early days, radio operation was only possible from two-seater aircraft - the pilot had to fly, thesecond man usually had to act simultaneously as an observer, gunner and radio operator. When in the early days of air traffic the shortwave band was used, direct communication with the ground forces was possible, if receivers with similar frequency coverage were present. | ||
+ | |||
+ | {{ : | ||
+ | New aeronautical ground stations had to be acquired as the already available shortwave equipment did not cover the new frequency range. On some occasions, the technology in newly acquired aircraft made faster progress, then the ground equipment used on the airfields. So in some cases, ground stations had to be improvised from aircraft radios installed with a matching mains power supply in a rack. | ||
+ | |||
+ | In the mid-sixties, | ||
+ | |||
+ | In the early days, flight operations were conducted from the command post over shortwaves. A central very powerful shortwave transmitter was also used for air raid alarm messages: [[S-500|Sender Emil]].\\ | ||
+ | After the shift of the ground - air communication into the VHF range, it turned out, that also the communication between the airfields the exchange of messages with the air defense had to be reorganized. The VHF transmitters had only line of sight propagation, | ||
+ | |||
+ | Initially, the aeronautical ground stations were given alphabetic names, such as the C-station or H-station. Later according to the new nomenclature from 1951, designations according to the pattern SE-0xx were given. | ||
+ | A suffix designates the kind of station when an aircraft station with the same number exists. So a /m stands for " | ||
