The objective of this paper is to present theories of scalar airborne gravimetry and to publish the related software to interested readers for free access. Numerical procedures and techniques are developed to compute velocities and accelerations from GPS-determined positions. A method based on the correlation analysis of raw gravity reading and vertical acceleration of aircraft is used to corre...

We present a 27-days long common view measurement of an absolute cold atom gravimeter (CAG) and relative iGrav superconducting gravimeter, which we use to calibrate the scale factor. This allowed us push CAG long-term stability down level 0.5~nm.s$^{-2}$. investigate impact duration on uncertainty in determination correlation factor show that it is limited about 3\textperthousand~by coloured no...

An airborne gravimeter is one of the most important tools for gravity data collection over large areas with mGal accuracy and a spatial resolution of several kilometers. In August 2012, a flight test was carried out to determine the feasibility and to assess the accuracy of the new Chinese SGA-WZ strapdown airborne gravimeter in Greenland, in an area with good gravity coverage from earlier mari...

Abstract We present the construction of a two-state model atomic gravimeter and associated Kalman recursion to estimate gravity acceleration from an gravimeter. It is found that estimator greatly improves estimation precision in short term by removing white phase noise. The residual noise estimates follows for more than $100\ \text{s}$ highlig...

An experiment comparing the location accuracy of gravity matching-aided navigation in the ocean and simulation is very important to evaluate the feasibility and the performance of an INS/gravity-integrated navigation system (IGNS) in underwater navigation. Based on a 1' × 1' marine gravity anomaly reference map and multi-model adaptive Kalman filtering algorithm, a matching location experiment ...

In atom interferometers based on two photon transitions, the delay induced by the difference of the laser beams paths makes the interferometer sensitive to the fluctuations of the frequency of the lasers. We first study, in the general case, how the laser frequency noise affects the performance of the interferometer measurement. Our calculations are compared with the measurements performed on o...
