| Abstract: | According to experimentizing influence of environment temperature no at the instrument constant of a type of gyrotheodite,we analyze and deal with the data of instrument constant on each temperature,and summarize the diversification accord with linearity rule.Then it is possible to realize automatic compensation for influence of temperature to instrument constant drifting.This has practical value in improving the orientation accuracy and nicety of gyrotheodolite. |
