    Abstract: A navigation system for use with moving vehicles includes target points proximate to a rendezvous site located on a first moving vehicle. One or more transmitters associated with the target points broadcast time-tagged target point positioning information. A navigation unit on a second moving vehicle utilizes a camera with known properties to capture images that include the target points. The navigation unit processes the image that corresponds in time to the positioning information, to determine the relative position and orientation of the rendezvous site at the second vehicle. The navigation unit utilizes the relative position and orientation and an absolute position and orientation of the rendezvous site calculated from the target position information and calculates an absolute position and orientation corresponding to the second vehicle.

A stored memory address table stores the memory address of each of the first and second blocks of data, at least one the blocks of data being stored a plurality of times in the memory address table. The data block corresponding to the acquired positioning information is identified, the memory address corresponding to that data block is read, the data block data indicated by the memory address is acquired, and the time difference data for the segment corresponding to the positioning information is acquired from the data block.

  • Patent number: 8391340
    Abstract: A low-cost GPS/GNSS receiver receives a satellite signal at an RF frequency (fRF). The GPS/GNSS receiver includes a front end section for receiving the satellite signal and generating a digital complex signal having a first bandwidth, the received satellite signal being converted into a complex signal before digitizing, a signal capturing section for searching for and acquiring the satellite signal, the signal capturing section including a capture memory, a baseband processor for tracking the acquired satellite signal, and a signal splitter coupled to the front end section. The signal splitter splits the digital complex signal into two bandwidths, by generating a narrowband digital complex signal having a second bandwidth substantially smaller than the first bandwidth. The signal splitter provides the narrowband digital signal to the capture memory and the wider first bandwidth digital complex signal to the baseband processor.

  • Patent number: 8391772
    Abstract: Precision surgical jamming of a target located at a distance uses GPS to coherently focus the jamming energy transmitted from a plurality of nodes. One of the nodes is designated as a master node and the remaining nodes are designated as auxiliary nodes. Each node tracks the carrier phases of satellite signals transmitted by a plurality of GPS satellites relative to a carrier phase of a reference oscillator in the respective node. The master node provides the tracked phase measurements along with its position information to all of the auxiliary nodes. The auxiliary nodes determine the phase offset of its reference oscillator relative to the reference oscillator of the master node based on the transmitted data. The transmit phase of a jammer transmitter in each of the nodes is then aligned to the phase of the reference oscillator to transmit a coherent focused beam to a distant target.

  • Patent number: 8019541
    Abstract: Data from GPS satellites within the field of view of a ground station are retransmitted to LEO satellites, such as Iridium satellites, and cross-linked if necessary before being transmitted to a user. The user is then able to combine the fed-forward data with data received directly from GPS satellites in order to resolve errors due to interference or jamming. Iridium and data aiding thus provides a means for extending GPS performance under a variety of data-impaired conditions because it can provide certain aiding information over its data link in real time.
