摘要： The described method and system provide an antenna feed for a slot antenna that may be patterned into a solar-reflective glazing layer with a virtual ground that is a short electrical distance from the antenna. One implementation of the present invention provides an antenna feed for a slot antenna patterned into the solar-reflective glazing used in a vehicle windshield. Because the antenna feed may incorporate a virtual ground that is a short electrical distance from the slot antenna, antenna performance may be improved over conventional on-glass vehicle antenna systems which use the vehicle chassis as a ground. Furthermore, patterning the slot antenna into the solar-reflective glazing layer and using a virtual ground in the antenna feed provides flexibility in antenna placement.

摘要： To facilitate GPS hardware selection and evaluate performance of vehicle integrated GPS hardware, including various types of GPS antennas and receivers, within different vehicle operating environments, embodiments of the invention are used to provide a simulator which does not require physical GPS hardware to simulate GPS system performance. Preferably, the simulator randomly generates one or more GPS system link budget variables, within predetermined performance bounds, in order to predict GPS system performance in a specific vehicle operating environment for a given antenna radiation pattern and/or GPS receiver. The simulator employs a Monte Carlo technique to evaluate the GPS system performance based on generated pools of link budget variables.

摘要： A software compass used during a GPS outage calculates vehicle heading and presents it upon request. The software compass gathers information from a yaw rate sensor, wheel steering angle sensor, wheel speed sensor, and PRNDL gear position sensor to calculate vehicle heading using a weighting algorithm. Because the yaw rate sensor data is a central factor in calculating vehicle heading, the quality of calibration of the yaw rate sensor is of importance. The disclosed calibration algorithm calculates the yaw rate bias and scale factors to calibrate the yaw rate sensor.

摘要： A method of improving a vehicle emergency call network used during an enhanced 911 call, which is especially useful in environments having degraded GPS signals. The present method utilizes an independent position enhancement algorithm, such as a dead reckoning algorithm, and converts the output of that algorithm into a compatible format compatible with a position determining entity (PDE). Some independent position enhancement algorithms return output in the form of position information (typically, two- or three-dimensional coordinates), however, most PDEs only accept information in the form of pseudo-ranges. Thus, the present method provides a technique in which the advantages of an independent position enhancement algorithm are enjoyed, yet a compatible output is sent to the PDE.

摘要： An antenna includes a CPW transmission line and a radiating portion. The radiating portion is coupled to the CPW transmission line and is substantially coplanar with the CPW transmission line. The radiating portion is configured to produce a first linear polarization at a first frequency, a circular polarization at a second frequency, and a second linear polarization at a third frequency. The radiating portion includes a conductive material extending from the CPW transmission line and forming a plurality of openings in the radiating portion. The openings are asymmetric with respect to a first region of the radiating portion that is disposed on a first side of the CPW transmission line and a second region of the radiating portion that is disposed on a second side of the CPW transmission line.
