LIGHTWEIGHT GYRO AZIMUTH THEODOLITE (LEAR NORTH SEEKING GYRO MODEL NO. 11NG530A)
Abstract:
Engineering tests of a lightweight gyro azimuth theodolite were performed at the GIMRADA test areas at Fort Belvoir, Virginia, and Fort Greely, Alaska. This instrument consists of a theodolite mounted on a gyroscopic reference nit, a combined electronic control unit and carrying case, and a tripod. The instrument is powered by internal batteries, weighs 31 pounds 6 ounces, and after 20 minutes operation time will permit read out of azimuth to any target sighted through the theodolite telescope. Testing under various conditions demonstrated that accuracies of 0.38 mil standard deviation or better could be obtained with the instrument.
