Application of Spread-spectrum Communication Technology to Theodolite External Communication

Theodolites as primary measuring equipment of external trajectory often exchange data with the center of measure and control.Adoption of spread-spectrum communication technology realizes long-distance communication in theodolite external communication.This paper recommends the application of spread-spectrum communication technology in theodolite external communication.The principle and typical work modes of spread-spectrum communication are introduced,the material realization methods of several typical work modes are explained,and the characteristics,system constitute,using scheme and system join drawing of spread-spectrum communication technology are recommended chiefly.At last,the measure results are obtained by testing in shooting range.Communication distance is more than 30 kilometer,communication capacity of dynamic image is more than 2 Mbps,communication capacity of dynamic image is more than 38.4 kbps;communication time delay is less than 1 s.The testing results show that the spread-spectrum communication technology applies well in theodolite.
