SGA-WZ: A New Strapdown Airborne Gravimeter
Inertial navigation systems and gravimeters are now routinely used to map the regional gravitational quantities from an aircraft with mGal accuracy and a spatial resolution of a few kilometers. However, airborne gravimeter of this kind is limited by the inaccuracy of the inertial sensor performance, the integrated navigation technique and the kinematic acceleration determination. As the GPS tec...
متن کاملA Comparison of Stable Platform and Strapdown Airborne Gravity
To date, operational airborne gravity results have been obtained using either a damped two-axes stable platform gravimeter systems such as the LaCoste and Romberg (LCR) S-model marine gravimeter or a strapdown inertial navigation system (INS), showing comparable accuracies. In June of 1998 three flight tests were undertaken which tested a LCR gravimeter and a strapdown INS gravity system side-b...
متن کاملLong-Term Stability of the SGA-WZ Strapdown Airborne Gravimeter
Accelerometers are one of the most important sensors in a strapdown airborne gravimeter. The accelerometer's drift determines the long-term accuracy of the strapdown inertial navigation system (SINS), which is the primary and most critical component of the strapdown airborne gravimeter. A long-term stability test lasting 104 days was conducted to determine the characteristics of the strapdown a...
متن کاملResults of tidal gravity observations in Tenerife, Canary Islands
c Tidal gravity observations have been carried out in Tenerife (Canary Islands) at the. base of the Teide volcano, more than two thousand meters above the sea level. The measurements have been done using a Lacoste&Romberg-G gravimeter (number 665), with electronic feedback during a period of six months. The results show, after a suitable correction of the ocean loading and attraction' effects, ...
متن کاملCorrection of the Betatron Coupling by Local Orbit Cross Talk
Analytical expressions, in presence of skew quadrupoles errors, have been derived to estimate the betatron coupling contribution to the vertical beam size and emittance [1]. The treatment of the betatron coupling is based on the matrix transport perturbation and related eigen vectors. The advantage of this approach is to be free of the usual resonant approximation and to allows a compact formul...
