Abstract

To meet needs of Space instruments for gyro system miniaturization, we design a 3-axis digital gyro signal acquisition system, based on L3G4200D. C8051F040 micro controller acts as the core controller in this system. The micro controller reads the MEMS gyroscope data through the I2C bus, and then passes the data through the RS232 bus to the host computer for processing. Finally, this paper analyzed errors of the system. The test result shows that the system has a small size, light weight, high reliability. This instrument can be widely used in space.
