Airborne Gravimetry Systems in strapdown technology with additional output of flight guidance data in real-time - also used for shipborne gravimetry
iCORUS is a family of light weight accurate strapdown airborne gravity gradiometers (AGG) and gravimeters with about 1 mGal accuracy (RMS).
iCORUS provides gravimetric disturbances measurements, gyro compassing and data for inertial navigation (PNT - Position, Navigation & Timing), surveying, guidance and stabilization. It contains dedicated, high performance gyros and accelerometers, an advanced GNSS engine and a dedicated signal acquisition and processing, based on iMAR's more than 30 years experience in designing and manufacturing highly accurate inertial measurement systems for surveying, navigation and control. iCORUS also shows significant advantages regarding weight, power consumption, robustness and mainteness, compared to other commonly used systems.
iCORUS covers applications, which require high accuracy, reliability, a flexible interface and easy integration and usage.
iCORUS is a so-called strapdown airborne gradiometer, which has significant advantages compared to standard gradiometers regarding flight turbulences. iCORUS widthstands accelerations up to 20 g in operational mode. With its weight of 18 kg it is also much lighter than all other systems, which has an immedeate impact on fuel saving or mission duration. As usual, best results are obtained as with every other technology when flying with monimal motion dynamics, i.e. on constant height.
