A system and method to opportunistically receive and use measurements on a priori unknown radio signals, not intended for radio navigation or geolocation, in conjunction with aiding data to improve navigation/geolocation position and time estimation yield and accuracy.

System and method for aiding data processing for signals of opportunity-based assured position, navigation and timing (PNT)

A system and method for estimating the position of a receiver and/or timing information for a receiver based on emissions from radio signal sources meant for applications other than position/navigation/time (PNT) estimation.

System and method for synthetic aperture based position, navigation, and timing

A system and method to opportunistically capture and use measurements of barometric readings from a plurality of mobile agents to determine the elevational position of one of the mobile agents.

System and method for robust navigation and geolocation using measurements of opportunity

A system and method for evaluating the interactivity of RF devices in a virtual RF environment having selective virtual spectrum users remotely controlled by a web browser, where the virtual spectrum users have selectable interactivity parameters, and the virtual RF spectrum can be selectively changed, and the performance of the virtual spectrum users is evaluated and assigned scores as a function of the evaluation to determine which virtual spectrum user receives the highest amount of points.

Interactive RF system testing system and method

A system and method for testing an adaptive RF system in an emulated RF environment using a feedback control module to efficiently and accurately evaluate the performance of the RF system under test in the search space.

Adaptive RF system testing system and method

A system and method to opportunistically use measurements on a priori unknown radio signals, not intended for radio navigation or geolocation, to improve navigation/geolocation position estimation yield accuracy and efficiency.

System and method of using measurements of opportunity with vector tracking filters for improved navigation

A system and method for testing wireless transceivers in a virtual wireless environment including emulating an RF environment, creating virtual spectrum users having selectable transmission parameters and physical characteristics and evaluating the operation of the wireless transceiver in the virtual wireless environment.

Wireless transceiver test bed system and method

A system and method of determining the location of a mobile device using signals of opportunity, derived time stamps and sharing of signal information with other mobile devices.

Performance improvements for measurement of opportunity geolocation/navigation systems

A system and method to opportunistically capture and use measurements on a priori unknown radio signals, not intended for radio navigation or geolocation, to improve navigation/geolocation position estimation yield and accuracy.

A system and method for a network analysis system operating in a wireless communication system with repeaters is disclosed. Embodiments of the system and method enable the network analysis system to determine if signals being received by the network receivers arrive directly from a target mobile appliance or if the signals are passing through a repeater. The repeaters through an augmentation measure attribute of a received signal to a network manager and based on these attributes it is determine whether the signal is served by a repeater or other network device.

System and method for detection of mobile operating through a repeater

A system and method of applying a known modification in the form of a distortion to a signal to enable a determination if a signal received by a first node is received directly from a second node or indirectly through a repeater. The repeater receives a primary signal and creates a secondary signal as a function of the primary signal and a known distortion, wherein the known distortion identifies the repeater. The primary signal is transmitted and injected with the secondary signal as the first signal to the primary receiver.

System and method for identifying the path or devices on the path of a communication signal

A system and method of applying a known modification to a signal to enable a determination of a signal received by a first node is received directly from a second node or indirectly through a repeater. The repeater receives a primary signal and creates a secondary signal as a function of the primary signal and a known modification, wherein the known modification identifies the repeater. The primary signal is transmitted and injected with the secondary signal as the first signal to the primary receiver.
