摘要： A navigation system includes an inertial filter that uses relative yaw values as an observable for attitude updates. The system calculates the relative yaw values based on carrier phase measurements , e.g., phase windup measurements, of navigational signals received at an antenna. The use of the relative yaw values as an observable in the inertial filter allows the system to improve estimates of associated biases, and also to continue to estimate the associated biases in low dynamic environments.

摘要： An integrated GNSS signal having a plurality of signal components with arbitrary power allocation may be processed. In an embodiment, an integrated signal processing unit of a GNSS receiver may generate in parallel complex rotated samples for a sample of the integrated signal. The complex rotated samples (e.g., early and late complex rotated samples) may be accumulated in parallel in a window that spans any arbitrary width that is less than or equal to a number of code chips in a PRN code sequence. In another embodiment, the integrated signal processing unit may sequentially generate complex rotated samples for the sample. The complex rotated samples (e.g., early, punctual, and late complex rotated samples) may be sequentially accumulated in the window. The GNSS receiver may utilize the accumulated complex rotated samples to perform correlation techniques, perform multipath mitigation techniques, and/or track the integrated signal.

摘要： An encapsulated multi-band monopole antenna is provided. Two or more sets of at least four monopole elements are encapsulated in a substrate. Conductive paths are arranged so that each element of a set of monopole element is connected to an element of each of the other sets of monopole elements.

摘要： A switching mode front end surge protection circuit protects downstream devices from a load dump. Specifically, the switching mode front end surge protection circuit includes a metal-oxide-semiconductor field-effect transistor (MOSFET) that operates in either one of two modes based on an input voltage provided by an alternator. When the input voltage is less than a voltage threshold value, the MOSFET operates in a pass-through mode. When the input voltage is greater than the voltage threshold value, the MOSFET operates in a switching mode to oscillate between an on state and an off state.

摘要： 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. The navigation unit then initializes its component inertial subsystem using a local position and orientation that are based on the calculated absolute position and orientation of the second vehicle.
