Office of GEOINT Sciences: Geodetic Survey Tools

The Geodetic Survey Division (Ranges) uses the most modern geodetic surveying equipment and data acquisition techniques to produce quality products for their users.
	Ashtech Model Z-XII GPS Receiver Dual frequency P-Code receivers, L1/L2.
	Geodimeter 540 Using conventional geodetic survey techniques, the Geodimeter 540 is used for measuring angles, distances, and differences in elevation.
	LaCoste and Romberg Relative Gravity Meter Model-G The Model-G gravity meters, used to measure relative gravity, has a range of over 7000 milligals, and a reading accuracy of +/- .01 milligal.
	A35M Astrolabe The A35M is a self-contained system providing data collection for real-time astronomical positioning. It is specifically designed to be field portable for accurate determination of astronomic latitude and longitude.
	Kern DKM 3AX Theodolite This instrument is capable of measuring angles and azimuths to a 10th of an arc second, meets the precise requirements of geodetic surveying. It is used to observe first and second order triangulation, and astronomic azimuths.
