Gyrotheodolites are an older, but accurate way to find true north. They can be used on the Earth's surface, but these days they tend to be used for surveying underground, in tunneling and mining applications. GPS surveying methods are replacing gyrotheodolite methods for this application on the Earth's surface. Gyrotheodolites are surveying instruments composed of a gyroscope attached to a theodolite. There is more information about gyrotheodolites here. When used underground, they are the best way to establish the initial surveying reference points underground.
