National Geospatial-Intelligence Agency (NGA)

NGIA Logo The National Geospatial-Intelligence Agency (NGA) mission at WSMR is to provide accurate and timely expert analysis of worldwide gravity, satellite and positional information including imagery and mapping control for navigation, safety, intelligence, positioning and targeting in support of national security objectives.  NGA provides geodetic positions based on the World Geodetic System 1984 (WGS 84) and orthometric heights based on Earth Gravity Model of 2008 (EGM 08).  The NGA range offices provide astro-geodetic deflections, geoid heights, gravity values, precise distances, true azimuths, astronomic positions, azimuths and geodetic control to accuracies of one part- per-million.  Increased accuracies are achieved using state-of-the-art equipment and techniques to precisely locate the impact points of missile components and other test debris for flight safety, recovery, and post-test analysis.  The quick responsiveness of the NGA range offices to customer requirements is key to keeping time-critical weapons tests on schedule.  Our inability to provide this response would have huge impacts on systems testing as they rely solely on NGA survey data for accuracy and range safety.

To request NGA geodetic survey support for WSMR projects, please send the completed 'NGA Survey Request Form' shown on this page to the office closest to the location of the project site:

Requests for projects north of Range Road 10 should be referred to our Holloman office at:

Requests for projects south of Range Road 10 should be referred to our White Sands office at:

Note: please submit 'NGA Survey Request Form' at least 15 days in advance of the date survey services are required.
