Azimuth Pointing System (APS)

The Azimuth Pointing System™ (APS) is a GPS-based compass that provides True North or Grid North azimuth, GPS or UTM position – all in one device. It also has an integrated inclinometer, which allows the system to provide a complete orientation solution. With an LTI TruPulse Laser Rangefinder, the APS is a powerful all-in-one total station that does not require benchmarks or backsights to produce remote GPS coordinates. Since the APS is not using the earth’s magnetic field to determine azimuth, it is not affected by ferrous anomalies (metal) from the ground or surrounding structures.
