NOAA, Aurora partner on gravity measurement program

Aurora Flight Sciences´ Centaur optionally-piloted aircraft (OPA) is supporting NOAA´s new airborne gravity survey efforts to collect gravity measurements across the Unites States for the Redefinition for the American Vertical Datum (GRAV-D) program, the company said.

Under the current survey, Aurora is collecting gravity data in a region of North Carolina to fulfill NOAA´s GRAV-D program needs and to fill gaps in the existing data sets used to define the US vertical datum. Through the GRAV-D program, Centaur´s data is helping to increase the accuracy of elevation measurements to determine where water will flow, which is instrumental for scientists, urban planners, agriculture and construction industries, and flood control managers.

In November 2016, Centaur surveyed the proposed high-speed train route in Northern and Southern California. Equipped with the TAGS-7 gravimeter sensor from Micro-g LaCoste, Centaur gathered specific data to help authorities develop a comprehensive model of the earth´s structure along the proposed rail route.

The GRAV-D Program will continue to use the Centaur OPA and the Micro-G system to fulfill NOAA´s gravimetry requirements this spring.
