Location Accuracy Improvement Using a priori Probabilities

Номер: US20120052835A1
Принадлежит: Trueposition Inc

A large volume of high accuracy location data is determined in many commercial wireless networks from location based services (LBS) and, in the United States, for E911. Uplink-Time-Difference-of-Arrival (UTDOA) and Assisted GPS (AGPS) are the predominant geolocation technologies providing these high accuracy locations. In the US alone over 10 million wireless subscribers are located every month because they dial the national emergency number “911” on their mobile phones. This rich set of location data provides an a priori distribution of the location of subscribers in the wireless network. All digital wireless communications networks have a mechanism for the subscribers to time synchronize their handsets to the network. This mechanism provides a band of ranges from the serving cell site to the handset. An a posteriori location estimate can be determined very quickly by considering the a priori distribution of callers in the range band that the current subscriber is in.

Method for calibrating a propagation-time-based localization system

Номер: US20120122484A1
Принадлежит: SIEMENS AG

In a method for calibrating a propagation-time-based localization system in a computer-assisted manner, the position of a mobile object in a predetermined environment can be determined by detecting propagation-time-based variables of multiple base stations, wherein the propagation-time-based variable of a base station represents the propagation time of a signal between an object radio unit and the base station. The object is moved and the variables of the base stations are detected in the process at multiple measuring times. The minimum value of the variables of a base station is associated with a predefined minimum distance between the object and base station and the maximum value with a predefined maximum distance. A predefined dependence of the distances between the object and base station is scaled to the association of the minimum and maximum value. The scaled dependence is then used when determining the position of the mobile object.

TAGLESS RADIO FREQUENCY BASED SELF CORRECTING DISTRIBUTED REAL TIME LOCATION SYSTEM

Номер: US20130231131A1

Services based on radio frequencies like GPS, RFID, GSM, CDMA, Wi-Fi or Bluetooth triangulation allows us to know, with some level of confidence, the position of a mobile device. However, those methods rely on special software and/or hardware. They also fail inside buildings since they cannot provide fine granulated values with a high level of accuracy. Each radio frequency device (mobile or not) emits a signal with a given strength and identification (Mac address or similar) to the air. The signal is captured by our nodes (at least 2 of the nodes), that measures the strength of the signal and therefore calculate the distance estimation. Since the signal is affected by electromagnetic noise, number of people in the building, or even temperature, the suggested system self corrects the values by knowing the distance between the nodes and measuring the signal strength. This gives to the system a very low error margin of about 1%. Some applications rely on real time tracking solutions, that traditional tracking systems cannot provide or need to provide tags to follow devices. The system here presented is distributed to be able to process the signal in real time (connected via a high speed network), with low latency and also stores the location estimation, device identification and time collected for analytics and reporting.
