Knowledge about the position of a user's mobile handset device constitutes a valuable information for emerging location-based services and applications. While satellite-based navigation systems are the chosen technology for outdoor, rural and semi-rural environments, location in urban canyon or indoor navigation is still unsolved. In this paper, we exploit the fact that handsets are usually surrounded...
In this paper, we study a new GNSS/INS tight integration algorithm. The underlying idea is to obtain user's position as the solution to a constrained version of the GNSS optimization problem, where classical trilateralization is constrained by INS measurements. This leads to a linearly constrained least-squares problem that can be efficiently solved in worst-case polynomial time. The performance of...
