Abstract
A method of using a survey system comprising at least one sensor. The method comprises operating the survey system to provide information regarding the orientation of the sensor relative to the Earth at a first resolution level while the sensor is a first distance relative to the Earth's surface and operating the survey system to provide information regarding the orientation of the sensor relative to the Earth at a second resolution level while the sensor is a second distance relative to the Earth's surface. The second distance is larger than the first distance. The second resolution level is higher than the first resolution level.
