The SCOUT uses several gyroscopes to track its positional accuracy. These gyroscopes use the Coriolis force to measure movement in 3 axes (following Newton’s law of motion). Corrections are applied by a magnetometer to obtain and maintain the accurate orientation.
As anyone familiar with boreholes will appreciate, using gyroscopes or magnetometers to orient oneself in a mining environment where magnetic orientation can be severely compromised is problematic. To overcome this, Geosight developed and patented a unique method to maintain azimuth orientation without magnetic correction.
This method is based on the closed loop that is used in surveying to correct for accumulated errors that occur when surveying long stretches without any means of correcting (no GPS or geodetic markers.) Using this method, the surveyor reverses their survey back to a known point (the same loop or different) and measures the accumulated error that occurs, then 0’s out the error to get the actual survey measurement which in turn corrects for the deviation that occurs.
