Abstract: The present invention includes a method for a combined use of a local positioning system (174), a local RTK system (150) and a regional, wide-area, or global differential carrier-phase positioning system (100) (WADGPS) in which disadvantages associated with the local positioning system (174), the RTK (150) and the WADGPS (100) navigation techniques when used separately are avoided. The method includes using a known position of a user receiver (142) that has been stationary or using ah RTK system (150) to initialize the floating ambiguity values in the WADGPS system (100) when the user receiver (142) is moving. Thereafter, the refraction-corrected carrier-phase measurements obtained at the user GPS receiver (142) are adjusted by including the corresponding initial floating ambiguity values and the floating ambiguity values are treated as well known (small variance) in subsequent processes to position the user receiver (142) in the WADGPS system (100).

Abstract: In one embodiment of a positioning system, a transmit element is configured to transmit at least one electromagnetic pulse having a carrier signal frequency. An antenna array with a plurality of receive elements includes at least two receive elements separated by a spacing more than a half wavelength. Each of the at least two receive elements is configured to receive a return signal over a period of time. The return signal includes a return pulse from an object within a detection area of the system. The wavelength corresponds to the carrier signal frequency of the transmitted pulse. A detector is configured to process the return signal from one receive element and the other receive element so as to isolate the return pulse received at each of the at least two receive elements and thereby determine a position of the object in relation to the system.

Abstract: A positioning system includes one or more active landmarks and a device. The device transmits an electromagnetic pulse having a polarization and receives return signals over a period of time. The device may preferentially receive return signals having the polarization. The return signals include at least one return modulated pulse from at least one active landmark. The device processes the return signals to isolate the return modulated pulse from the return signals and to determine a range from the device to the active landmark. The device optionally moves in a particular direction while receiving the return signals, detects a Doppler shift in the return modulated pulse portion of the return signals and determines an angle between the particular direction and a straight line between the device and the active landmark.

Abstract: A positioning system includes a plurality of devices configured to exchange RF signals with one another. A first device periodically receives a message from each other device during time slots assigned them. The received message includes information representing a time of arrival at the other device of a respective message transmitted by the first device. A time of arrival of the message from each of the other devices is determined by the first device. The first device periodically transmits messages to the other devices, each transmitted message including information representing the determined time of arrival for at least one of the other devices. A range from the first device to each of a plurality of the other devices is determined as function of the determined time of arrival of the message from the other device and the time of arrival information in the message from the other device.
