Abstract: An antenna-receiver communication system comprises an antenna conductor, antenna, and intelligent antenna controller. The intelligent antenna controller and antenna are connected via a conductor for providing power to the antenna from the intelligent antenna controller, and a received signal from the antenna to the intelligent antenna controller. The intelligent antenna controller is configured to provide voltage to the antenna for its operation, and to systematically alter the provided voltage level to communicate information to the antenna. The antenna is configured to communicate messages to the intelligent antenna controller by systematically altering the current consumed by the antenna. Both the intelligent antenna controller and antenna are configured to decode received messages and act on them. A method for communication between an intelligent antenna controller and antenna utilizing patterns of voltage and current fluctuation over the conductor providing power from the intelligent antenna controller to the antenna is also provided.

Abstract: An integrated machine guidance system for guiding a critical device of a machine includes global navigation satellite system (GNSS) antennas, a GNSS receiver, a guidance controller, and a wireless communication system enclosed in a housing. The guidance controller is adapted to compute an actual position of the critical device and determine a direction that the critical device should move to arrive at a desired position. The housing may be coupled to a mounting element, which is attached to the critical device. A display unit is in communication with the guidance controller, and is coupled to the housing so that it is visible to an operator in the cab of the machine. The guidance controller may communicate with another display unit located remote from the housing via the wireless communication system. Each of the display units can provide an indication of the direction that the critical device should move.

Abstract: A complex and intricate GNSS antenna that is created using inexpensive manufacturing techniques is disclosed. The antenna combines a loop antenna and a cross dipole antenna together, in a single plane, to create an optimal GNSS gain pattern. The antenna structure is symmetric and right-hand circular polarized to force correct polarization over a wide range of frequency and beamwidth. The feed structure is part of the antenna radiating element.

Abstract: An RF (e.g., GNSS) interference mitigation system and method uses a switchable bank of filters for selectively blocking signals in predetermined bandwidths based on detecting strong, interfering signals with an interference detection circuit including a sniffer antenna. A low- strength RF (e.g., GNSS) system can be combined with a spectrally-close high-strength, telecommunications receiver system for cooperative control. Alternatively, an RF receiver can detect tones, changes in DC bias or level changes to activate a filter selection switch.

Abstract: Global Navigation Satellite System (GNSS) signals are first received and then down converted to an intermediate frequency (IF) and digitally sampled. The sampled signals are multiplied by a local replica of the incoming IF carrier (I ref generator and Q ref generator). The purpose is to remove the Doppler and move the results to baseband for later accumulation processing. Two parallel correlation kernel modules, one kernel assuming the navigation data D is 1 while the other assuming navigation data D = 0 or (-1), are provided. The correlation kernel takes the code numerically -controlled oscillator (nco) phase of the prompt signal as input, and generates four output signals that are multiplied by the Doppler-removed incoming sample signal. An implementation of the pulsed signals accommodates navigation data D = 1 and D = 0 or (-1).

Abstract: Disclosed is a system and method for detecting false Global Navigation Satellite System (GNSS) satellite signals. False GNSS satellite signals can be used malevolently to take control of a body such as a vehicle or ship that is using GNSS satellite signals for navigation. In some embodiments a GNSS attitude system is used to detect the false GNSS satellite signals. The GNSS attitude system measures the code or carrier phase of the GNSS satellite signals at two or more antennas to detect the false GNSS satellite signals. In some embodiments the attitude system computes first measured and second estimated carrier phase differences in order to detect the false GNSS satellite signals. The attitude system may compute the attitude of a baseline vector between the two antennas. Once false GNSS satellite signals are detected, the method can include preventing the attitude determining system from outputting position or location data.

Abstract: Disclosed is a device and method for determining the direction of a false Global Navigation Satellite System (GNSS) satellite signal transmitter. False GNSS satellite signals can be used malevolently to take control of a rigid body such as a vehicle or ship that is using GNSS satellite signals for navigation. The GNSS device according to the invention computes a plurality of range differences, where each range difference is the difference between a range from a first GNSS satellite to a first GNSS antenna, and the range from the first GNSs satellite to a second GNSS antenna. Each of the plurality of range differences is correlated to a rotation angle of a baseline vector extending from the first GNSS antenna to the second GNSS antenna. The rotation angles and their corresponding range differences can be used to indicate the direction of the false GNSS satellite signal transmitter.
