Further, the system can be modularly configured for use in location signaling environments ranging from urban, dense urban, suburban, rural, mountain to low traffic or isolated roadways. The system is useful for 911 emergency calls, tracking, routing, people and animal location including applications for confinement to and exclusion from certain areas.

Locating a mobile station and applications therefor

In a global positioning system (GPS)/self-contained combination type navigation system for a vehicle, the GPS navigation data are received by the GPS antenna of the navigation system which are simultaneously transmitted from more than 3 pieces of satellites inclusively. From the GPS navigation data, GPS type velocity data is calculated, whereas self-contained type velocity data is calculated from self-contained type navigation data such as azimuth data and drive-distance data of the vehicle. Only when a difference between the self-contained type velocity data and the GPS type velocity data exceeds a threshold velocity, the GPS type velocity data is voided so as to determine the present position of the vehicle.

GPS/self-contained combination type navigation system

PURPOSE: To improve the reliability of the results of measurement by comparing a position measured by satellite navigation with the one assumed by a dead reckoning navigation instrument. CONSTITUTION: A position P 1 measured by a satellite navigation instrument 1, a DOP value that is the index of the deterioration of position measurement based on the location of a satellite used for the position measurement and an assumed position P 2 obtained by a dead reckoning navigation instrument 2 are inputted to an error tester 3. In the error tester 3, a standard deviation σcorresponding to the inputted DOP value is fetched from a standard deviation memory 4 and whether the position P 1 is present in a circle with a center located in the position P 2 and with a radius σ is tested. When the position P 1 exists in the above-mentioned circle, the position P 1 is recognized as correct and a position measuring instrument is changed over to the satellite navigation instrument 1 by a position measuring instrument changeover unit 5. When the position P 1 exists outside the above-mentioned circle, the position P 1 is judged as uncertain and the position measuring instrument is changed over to the dead reckoning navigation instrument 2.

Gps position measuring instrument

PURPOSE: To take a measurement with higher accuracy by outputting a more reliable result between results of a radio wave navigation device and a dead reckoning navigation device and correcting the device with less reliability. CONSTITUTION: A position measuring instrument has the radio wave navigation device 1 which measures specific kinds of data on a position, an azimuth, a speed, etc., and a dead reckoning navigation device 2 which measures specific kinds of data on the position, azimuth, speed, etc., and is further provided with a reliability decision device 6 which inputs measurement data from both devices, decides which of both data have higher reliability, and outputs the more reliable measurement data and a calibrating device 7 which outputs calibration data to the device which outputs the less reliable data so that the device can outputs data nearly as reliable as the data that the more reliable device outputs. The dead reckoning navigation device 2 is equipped with an azimuth detector 4 and a range detector 5 and the azimuth detector 4 is composed of, for example, a terrestrial magnetic sensor and detects the traveling azimuth θI of a vehicle. Further, the range difference detector 5 outputs a unit pulse signal every time the vehicle travels by constant distance. COPYRIGHT: (C)1988,JPO&Japio

Hybrid type position measuring instrument

PURPOSE:To prevent a serious accident due to the jump phenomenon of GPS position measurement from occurring by employing both the GPS position measurement using an artificial satellite and self-contained position measurement based upon azimuth data and moving distance data. CONSTITUTION:An antenna 11 for GPS which receives radio waves from plural artificial satellites is connected to a reception part 12 and its output is inputted to a position measurement arithmetic part 13 which finds the two-dimensional position and three-dimensional position of a moving body. An azimuth sensor 14A which detects a moving azimuth and a distance sensor 14B which detects the moving distance are provided and connected to a self-contained position detecting means 14. The result of the arithmetic part 13 is sent to a position detecting means 14 through a calibrating means 19 to make necessary correction. The position determining means 15 has a selecting function and employs it when the GPS position measurement is possible or self-contained position detection when not to supply data to a drawing function part 17, thereby displaying the position on a map by a display device 18.

Gps navigation system

PURPOSE:To improve the reliability of the position and speed of a moving body by processing radio waves received from plural satellites into one-channel sequence data by a CPU, and measuring and comparing variation in offset from the frequency of a reference oscillation with a threshold value. CONSTITUTION:When a power source is turned on, the radio waves received by an antenna 1 from the plural satellites are amplified 2 and converted to the 1st IF by the reference oscillator 10 and a frequency synthesizer 9. The 1st IF is amplified 4 and converted 5 to the 2nd IF, which is amplified 6 and phase-compared 7 with the output of the frequency synthesizer 9. A dummy noise code is generated 13 wit the output of a CPU8 under the control of a dummy noise code period numeral control oscillator 14 to impose modulation 11 upon the output of a numeric control oscillator 12 for carrier phase synchronization, so that the output is inputted to the 2nd frequency converter 5. A double loop from the CPU8 back to the CPU8 is formed eventually to track a carrier in series to calculate whether the offset of the frequency is large or small. Consequently, the reliability of the position and speed of the moving body is decided.
