Abstract
The paper discusses the problem of heading alignment of downhole gyroinclinometers in latitudes up to 80° N. It is shown that the required alignment accuracy may be achieved using inertial measurement unit with fiber-optic gyros (FOG IMU) or so called global navigation satellite system (GNSS) compass. Test results for FOG IMU (IXSEA) and GNSS compass designed by Elektropribor are represented.
