The use of laser gyroscopes in multifunction Inertial Reference Units was investigated in the laboratory using a single-axis revolving platform. The use of the laser gyroscope as sensor for inertial navigation shows a good reproducibility to the average slope of the characteristic (0.5 ppm). For the measurement of single angular shifts, the laser gyroscope shows a constant error of 2.9 sec and an error between 0.004 and 0.0016 deg/hr depending on the interval length. The dynamic investigation of the laser gyroscope as sensor for flight guidance shows an amplitude distortion below 1 percent and a phase shift below 0.4 mrad in the whole frequency range up to 100 Hz.
