SYLEDIS, A RADIOPOSITIONING SYSTEM

A pulse radiopositioning system, designated SYLEDIS, has been developed, which does not rely on radar techniques. The use of compression of long pulses by correlation methods, and of a carrier wave in the 420-450 MHz band, has resulted in a highly accurate system, insensitive to soil conductivity, exhibiting no ambiguity problem, capable of ranges of 2 or 3 times the line of sight, and not limited by obstacles of reasonable size. SYLEDIS is highly flexible and operates in the range or hyperbolic modes.
