The DIGS™100 Inertial Guidance System is an IP68 MEMS AHRS designed for downhole orientation and directional guidance applications. The small size of this AHRS (1” diameter by 2.125” length) enables its use in tight drilling and utility spaces. The DIGS™100 Inertial Guidance System provides temperature compensated RS422/RS485 output of pitch, roll, and yaw angles.
