摘要： A unit is configured to provide acceleration, velocity, and position information for one or more points on a vehicle. The unit includes an integrated global positioning satellite system (GPS)/inertial navigation system (INS) and at least one remote velocity sensor. The remote velocity sensors include three orthogonal accelerometers and a digital signal processor configured to receive signals from the accelerometers. The remote velocity sensors are mounted at points on the vehicle where acceleration, velocity and position are to be determined. Data from the sensors is slaved to data from the integrated GPS/INS, and the unit is configured to transform data from the sensors to a navigation frame utilizing a sensor frame to navigation frame attitude matrix.

摘要： The jammer response circuitry of the present invention operates to control correlation circuitry in a GPS receiver based on an occurrence of a transmission from a wireless transmitter, thereby avoiding performance degradation in th GPS receiver due to interference caused by the transmission. In general, the jammer response circuitry activates a control signal during the transmission, thereby temporarily stopping the operation of the correlation circuitry. More particularly, the accumulation of results of a correlation of a received signal with a generated frequency and a generated code having numerous time offsets is temporarily stopped when the control signal is activated and resumes operation when the control signal is deactivated.

摘要： A signal deformation monitor that corrects for bias caused by receiver front end signal deformation is disclosed. The signal deformation monitor includes a correlator that determines a plurality of correlation measurements along a correlation curve. The correlation measurements are transformed by a correlation transformation. The correlation transformation subtracts the mean of the correlation measurements over all tracked satellites from each of the correlation measurements calculated by the correlator. The transformed correlation measurements are independent of the front end signal deformation, resulting in a deformation monitor that will more accurately detect satellite signal deformation.

摘要： When position measurement accuracy of the present position which the base station distance and position measurement part measures from radio waves coming from base stations is not good, a GPS distance and position measurement part measures the present position from radio waves coming from GPS satellites. When position measurement accuracy of the present position obtained by the GPS distance and position measurement part is not good, a position measurement accuracy analysis part compounds the present position obtained by the base station distance and position measurement part with the present position obtained by the GPS distance and position measurement part, and calculates a new position within a range of overlap between a position measurement error of the present position obtained by the base station distance and position measurement part and a position measurement error of the present position obtained by the GPS distance and position measurement part.

摘要： A low-cost, solid-state position sensor system suitable for making precise code and carrier phase measurements in the L1 and L2 bands of GPS uses an ordinary, low-cost OEM card single-frequency carrier phase tracking C/A code receiver and includes low-cost hardware for sensing the L1 and L2 components of GPS carrier phase. Such measurements are suitable for general use in a variety of fields, including surveying. They are also of sufficient quality to be used in controlling heavy machinery, such as aircraft, farm tractors, and construction and mining equipment. A C/A code continuous tracking GPS receiver is used to produce GPS positioning fixes and real-time L1 carrier phase measurements. This C/A code receiver generates timing and reference information for a digital sampling component. This sampling component processes the L1 and L2 signals from the GPS signals in view. A digital signal processing component coupled to this sampling component processes the raw samples in synchronous, batch form including a step to precisely unwrap the P(Y) carrier phase to baseband. The receiver outputs synchronous, carrier phase measurements associated with each ranging source and signal observable. The synchronous raw carrier phase measurements from the continuous tracking C/A code receiver and the digital sampling component may be used to resolve the cycle ambiguities to each ranging source with respect to a reference station at a known location. Within a short interval typically tens of seconds from initial turn on, continuous, synchronous raw measurements are provided by the GPS receiver and processed into precise position fixes.

摘要： A navigation receiver comprises a digital sampler that precedes digital signal processing which can operate at a high rate and a low rate. If the high rate is selected for noise reduction by non-coherent averaging, the samples are averaged over time and transformed to the low rate. The digital signal processor is fed only low-rate samples in either case.
