Analysis of Long-Range LTE Radio-SLAM Navigation Approximated as a Periodic System

Dawson Beatty, Mark L. Psiaki

Abstract:	Work in recent years has demonstrated navigation capabilities using an unchanging set of cellular signals of opportunity in a predefined area, but the question of how such a scheme would fare over long-duration flights remains unanswered. This work presents a feasibility study examining the expected performance of a navigation algorithm relying on cellular signals of opportunity. The problem is posed as a simultaneous localization and mapping problem, since the states of the cellular signals must be jointly estimated with the user’s position and velocity. This work explores how much information about the position and clock bias states of the cellular signals in order to make a useful navigation system. An analysis method for determining the steady-state covariance is also derived by assuming that the system is periodic. Simulated results show that in a typical route with reasonable assumptions, a position RMSE of 12 m might be obtained. This study shows that cellular signals of opportunity are a feasible option for long-duration navigation, especially if the route can be flown more than once to obtain better estimates of cellular site positions.
