THE TORAN RADIOLOCATION SYSTEM
The TORAN radiolocation system has been used for many years for accurate positioning of ships, drilling platforms, aircrafts and helicopters. The position of mobile vehicles is provided by phase comparison of waves continuously transmitted by fixed shore stations. Shore transmitters are neither synchronized nor enslaved, and the stability of the LOP patterns is a specific feature of the TORAN principle. The sensitivity of the system is one to a few meters, ranges of up to 500 nautical miles are usually achieved, all shore stations operate unattended, an unlimited number of mobiles can use the system. Digital recording on board, and retransmission by telemetry of gathered data allows almost immediate automatic plotting of charts such as bathymetric, temperature, pollution charts. The accuracy and range of the TORAN system has allowed fishing-boats to use it for fishing close to rocks and wrecks in difficult areas. Many trawlers are now equipped with TORAN receivers, resulting in lesser damage to the fishing gear, more leisure time for the crew, and a much higher efficiency.
