Dynamic Gravity Systems (DgS) manufactures advanced gravity meters and systems for geophysical surveys on land, at sea, in the air, and underwater. Its instruments use full-feedback, zero-length spring sensors designed to measure across the worldwide gravity range and respond to the dynamic motions experienced aboard aircraft and ships. The technology does not require a spring-tension motor and is intended to deliver responsive, accurate measurements.

DgS offers airborne systems with inertial measurement unit platform control, magnetically damped marine systems featuring force-feedback beam measurement, portable land-survey sensors, and gravity systems designed for integration with underwater autonomous vehicles. The company also provides system upgrades, servicing, calibration, training, testing, and repairs. Its repair services cover specified air-damped meters from Lacoste and Romberg, ZLS, and Micro-g Lacoste, as well as Micro-g Lacoste’s magnetically damped marine meter and Turnkey Airborne Gravity System.

In addition to its products and technical services, DgS lists projects, gravity processing, tidal gravity computation, and publications among its resources.
