Estimability in Strapdown Airborne Vector Gravimetry,nalyse the estimabilities for integrated navigation systems, comprising a strapdown inertial measurement unit (IMU) and observations from global navigation satellite systems (GNSS). This concept will hereby be adapted to strapdown vector gravimetry, being a special application of a IMU/GNSS system.

Airborne Gravimetry for Geoid and GOCE,nd global geopotential models. Recently we have started flying two gravimeters (LCR and Chekan-AM) side by side for increased reliability and redundancy. Typical gravity results are at the 2 mGal rms level, translating into 5–10 cm accuracy in geoid. However, in rough mountainous areas results can b

Testing Airborne Gravity Data in the Large-Scale Area of Italy and Adjacent Seas,ly, roughly from latitude 36°N to 44°N. In this area, seven main tracks NW to SE were surveyed having a spacing of about 40 km and an altitude of 3,500 m, complemented by an eighth track in an altitude of 10,000 m. Four perpendicular cross tracks were also added..Amongst the geodetic-geophysical equ

Evaluation of GOCE-Based Global Geopotential Models Versus EGM2008 and GPS/Levelling Data in Northwravity field determination. Several Global Geopotential Models (GGMs) have been published based on the data collected during the roughly 4-year mission of GOCE. This study focuses on evaluation of the contribution of GOCE data for the representation of gravity field with significant improved accurac
