Latest Patents
One of his latest inventions is a method and system for calibrating wireless location systems. This invention relates to a method for calibrating a wireless location system (WLS) to enable the system to make highly accurate differential measurements such as time difference of arrival (TDOA) and frequency difference of arrival (FDOA). Calibration is accomplished by transmitting a signal from an unknown location and measuring at each of two receivers the parameter to be calibrated from that part of the received signal reflected or refracted from an object at a known location in the area. A differential measurement error is determined by comparing the expected difference in the parameter measurements with the actual difference in the parameter measurements. The expected difference is known, a priori, based on the locations of the receivers and the location of the object.
Another significant patent is a system and method for determining the location of a transmitting mobile unit. This system determines the location of a transmitting mobile unit equipped with a global positioning system (GPS) unit and a transmitter for transmitting an RF signal that includes an identification of the mobile unit and GPS location coordinates, if available. At least one receiver forms a first infrastructure and is contained within an area having good GPS reception for receiving a transmitted signal from the mobile unit when in the area relating to the identification of the mobile unit and the GPS location coordinates or other GPS data obtained from the GPS unit. At least one receiver forms a second infrastructure and is contained within an area having poor GPS reception for receiving transmitted signals from the mobile unit when in the area relating to an identification of the mobile unit and for measuring the angle of arrival and/or time of arrival, multipath profile, or other characteristics of transmitted signals from the mobile unit. A processor determines the location of the mobile unit based on the measured time of arrival and/or angle of arrival.
