Abstract: Devices, systems, and methods for determining azimuth, elevation, or object position relative to a baseline using an integrated sighting device. The integrated sighting device includes a GPS receiver, an inertial measurement unit (IMU), an optical aperture, a microcomputer, and a handheld housing. The integrated sighting device, during transit from a reference position to a sighting position, determines a first angle between the sighting position and the reference position based on carrier phase input received during the transit. Orientation input is received from the IMU at the sighting position as the integrated sighting device is aimed and sighted along a line of sight to the reference position. The baseline is generated based on a second angle of the orientation input correlating with the first angle. The baseline is used as a reference for determining azimuth, elevation, or position of other objects or devices.
