Each wing pod and the stinger house a single, temperature and axis-stabilised, miniature gravity sensor, together with one at the aircraft centre of gravity, acting as a reference. Typical dimension of the gradient triangle formed is 10 metres per side.
Te triangle of sensor data is compensated for aircraft movement by a laser system and then presented as a gradient vector and a slope angle. Sensor sample rate is 1KHz. Even when smoothed times 10, the delivered data rate is 100 points per second. At 140knots (260 km/hour), this is better than 1 metre along line resolution. SEEPFINDER and GRAVEX together with
high-resolution magnetometry, offer a fast, flexible solution for oil and gas exploration. Te unique combination of these airborne technologies, allows detection of offshore seepage and structures with the ability to follow structural trends through the transition zone and onshore. Te lightweight and compact equipment permits the airborne platform to carry maximum fuel allowing up to 1,500Km of data to be collected per day. Fast data processing times provide a fully integrated dataset giving clear results in a format that can be easily used to tailor additional exploration activities. ●
