The technology of high-precision positioning and attitude telemetry has become an important method for submarine and underwater platform connecting

while conventional technology such as radio distance measuring and infrared remote sensing technology are difficult to overcome the problem of operating distance is limited and quick attenuation of energy in water.To solve this problem

design a system of underwater positioning and attitude telemetry system based on acoustic positioning and attitude telemetry

and by high-precision acoustic ranging and position and attitude solution

realize remote boot and precise connection between submarine and target platform.Experimental datas show that this system has high-precision measurement and boot performance

the relative positioning telemetry is 5 cm and relative attitude measurement precision is 3°

which has good engineering application value.
