Impact of Uncertainties in Atom Interferometry on Strapdown Navigation Solutions
This paper examines the impact of systematic and stochastic uncertainties of atom interferometry-based sensors measuring accelerations and turn rates on strapdown navigation solutions. The sensitivities of the sensor to changes in the main readout and scale factor parameters are estimated analytically and compared to simulations with a sophisticated cold atom interferometer (CAI) sensor model. The performance of this model, including uncertainties in the selected parameters, is shown with the help of a Monte Carlo simulation.
