“…A detailed description of the non-synchronized solution can be found in [12] in which the authors propose Digital Audio Broadcast (DAB) stations instead of GPS satellites, but their proposal can easily be extended to A-GPS and GSM/UMTS. Again, the way in which the measurements are combined or weighted has an impact on the accuracy of the position estimate but not on the coverage.…”

This work presents a statistical field study of the availability of time sources for location in a true wireless network. Terrestrial (base stations) and satellite (GPS) sources were investigated in three different urban scenarios. The density function of a specific number of sources available for triangulation is presented along with other statistical data in order to assess coverage. Since the fusion of terrestrial and satellite sources to obtain the location in wireless networks has been proposed as a way of improving coverage, the joint density function and cross-correlation between the availability of both types of sources are also presented. This correlation depends on the scenario, leading to the conclusion that the improvement obtained through the fusion of sources depends on both the fusion type and the scenario.

“…The Global Positioning System (GPS) is the most popular positioning technique in navigation providing reliable mobile location estimates in many applications [1][2][3][4]. Thus wireless location systems offering reliable mobile location estimates have been studied by researchers and engineers over the past few years.…”

“…So, techniques were developed using filters to estimate the location of the user through the location information exchanged between the handset and the base station. Kalman Filter has been used in the localization process [4][5][6][7], due to the following advantages mentioned in [6]: (a) Kalman Filter [5,[8][9][10] processes noisy measurements and so it can smooth out the effects of noise in the estimated state variables by integrating more information from reliable data more than unreliable data and (b) Kalman Filter allows the combination of measurements from different sources (locomotion data) and different times. Kalman Filter was implemented for Global Systems for Mobile (GSM) position tracking in [6]: Kalman Filter was used for tracking in two dimensions and it was stated that Kalman Filter is very powerful due to its reliable performance, because it yielded enhanced position tracking results.…”

Abstract:In this paper we present two time invariant models mobile position tracking in three dimensions, which describe the movement in x-axis, y-axis and z-axis simultaneously or separately, provided that there exist measurements for the three axes. We present the time invariant filters as well as the steady state filters: the classical Kalman Filter and Lainiotis Filter and the Join Kalman Lainiotis Filter, which consists of the parallel usage of the two classical filters. Various implementations are proposed and compared with respect to their behavior and to their computational burden: all time invariant and steady state filters have the same behavior using both the proposed models but have different computational burden.

Location systems based on already-deployed cellular networks spend the resources of the underlying communications network. This paper proposes a middleware that reduces the consumption of resources and optimizes the location traffic load. This middleware, called MILCO (Middleware for Location Cost Optimization), is assumed to run on networks that can choose from among several location techniques (e.g. A-GPS, NMR, etc.). MILCO selects the optimum technique for each request, i.e. the location technique that provides the required quality of service (QoS) and minimizes resource operating expenses. In addition, MILCO takes advantage of ongoing location processes to reduce the overall expenditure of resources. The results show that MILCO reduces the rate of location-process failure and improves latency for location provisioning and resource usage in cellular networks.
