Gyrocompassing in GPS Denied Environments

Gyrocompassing in GPS Denied Environments

High accuracy navigation deep underground causes significant challenges due to the lack of a GPS signal, magnetic interference, and high temperatures. The technology developed in this program enable north finding by using an inertial reference.

This is done using a gyroscope which is sensitive enough to measure the rotation of the earth. As the earth rotates, the gyroscope is used to measure the rotation along a specific direction of the gyroscope. This program uses a specially designed gyroscope to measure the earth’s rotation in harsh environments along with custom tailored electronics and packaging to maximum the performance of the device.   

Project Impact

High accuracy gyrocompassing allows for the precise navigation when GPS or magnetic compassing is compromised. In downhole applications this allows for higher precision when targeting specific geology resulting in improved oil extraction or better energy transfer for geothermal wells. Beyond downhole applications this technology can also be used to improve navigation systems for self-driving vehicles.
