1.0 PURPOSE & BACKGROUND

The purpose of this contract is to perform a terrestrial gravity survey in the country of Mongolia to tie into existing holdings for the National Geospatial-Intelligence Agency (NGA). NGA has a mission-critical need for gravity data over the country of Mongolia. Specifically, terrestrial data is needed as a high-resolution data set for our Earth Gravity Model.

120.098 in the southeast.

3.) The Contractor shall survey to a distance of 25 km from the Chinese border into Mongolia.

4.) The Contractor shall simultaneously collect precise GPS locations and both orthometric and ellipsoidal heights.

5.) The Contractor shall obtain all necessary permissions from the Mongolian government such as the

General Authority of Border Protection Forces and the Ministry of Defense.

2.2 OPTION YEAR ONE

General Authority of Border Protection Forces and the Ministry of Defense.

3.0 CONTRACTOR DELIVERABLES

3.1 BASE and OY Contract Deliverables

NGA will receive the processed free-air and Bouguer gravity anomalies and orthometric heights in the

WGS 84 Reference System for all points collected in the base and option years listed above. The gravity anomalies shall be accurate to one (1) mgal and the orthometric heights shall be accurate to at least 50

cm. The gravity anomalies shall also be referenced to absolute gravity stations. The data format shall consist of: Latitude, Longitude, Orthometric Height, ellipsoid height, Free-Air Gravity Anomaly, Bouguer

Anomaly as displayed in the Point Gravity Anomaly Data Format Guide Below, and shall be supplied on appropriate electronic media.
