摘要:
An antenna arrangement for a GPS signal processing device having a circuit board is disclosed. In a preferred embodiment of the invention, the arrangement comprises an antenna member mounted to the circuit board. The antenna member includes a first surface, second surface and a third surface. The third surface adjoins the first and second surfaces. The first, second and third surfaces define a cavity within which is disposed dielectric material. At least one conductive connector comprising first and second ends is in communication with the antenna member first surface. An amplifier is in communication with each conductive connector second end.

In a membrane probing apparatus, the impedance of the interface between coaxial cables connected to the test instrumentation and the membrane supported co-planar waveguide that conductively connects to the probe's contacts is optimized by eliminating a ground plane in the interface board.
摘要:
A method of determining the distance traveled during an event by a mobile GPS receiver. The event comprises epochs. The method comprises receiving pseudorange data comprised of one of pseudorange differences or range rates. Each pseudorange difference, in turn, comprises a difference between a first pseudorange and a second pseudorange. The first pseudorange comprises the pseudorange between the receiver and a GPS satellite at a first epoch. The second pseudorange comprises the pseudorange between the receiver and the GPS satellite at a second epoch. The range rates comprise a range rate measurement taken by the receiver of the GPS satellite from the first epoch to the second epoch. Line-of-sight data comprised of at least one normalized vector between the receiver and the GPS satellite is then determined. Based on the pseudorange and line-of-sight data, incremental distance data is then determined. A sum over the event of the incremental distance data is then determined.
