Why Is Accurate Directional Measurement Important in Mining? Directional drilling plays an important role in underground coal mining, gas drainage, water…

Quick Answer Geophysical exploration spends money every kilometer of survey line, and the data is only as useful as its position…

Quick Answer Inertial navigation helps geophysical teams associate every sensor measurement with the platform’s position and orientation. When integrated with GNSS,…

Quick Answer Underground mines have no GPS, heavy magnetic interference, and a network of tunnels that all look the same. Mine…

Quick Answer Underground mines have no GNSS, and magnetic compasses fail near steel supports, electrical equipment, and magnetic ore bodies. A…

Quick Answer GNSS gives you position, but it cannot give you accurate attitude, it drops out under trees and between buildings,…

Quick Answer In oil and gas, a north seeker provides a true-north reference where GPS is blocked or the magnetic field…

Quick Answer A north seeker (north finder) is a gyro-based instrument that finds true north without GPS or a magnetic compass.…

Quick Answer MWD (measurement while drilling) uses fluxgate magnetometers and accelerometers to measure inclination, azimuth, and toolface in real time. It…

Quick Answer A fluxgate directional sensor measures the Earth's magnetic field to determine azimuth. It is low-cost, mature, and accurate but…
