Ericco’s ER-MG2-100 is a north seeking mems gyro, its main features as follows: 1. 0.02°/hr bias instability; 2. 0.005°/√hr angular random walk; 3. Small size 11 x 11 x 2mm. WebApr 5, 2024 · Gyro-theodolite is a combination of gyroscope and theodolite as shown in Fig. 3. The gyroscope has a high-speed rotor with a rotating axis in the horizontal plane. When the rotor rotates, the rotating axis generates a slow precession motion around the north direction in the horizontal plane.
