Abstract

PURPOSE:To make it possible to perform highly accurate position measurement n a broad range in real time by using the received data from a receiver for a moving-position measurement satellite and the correcting data from a correcting-data receiver, and obtaining the three-dimensional position coordinates of a moving body. CONSTITUTION:A moving position-measurement satellite receiver 31 receives a position measuring radio wave. A gyro-data processor 35 utilizes the signal from a gyroscope for inertial guidance for detecting the change in tree-dimensional position and forms the displacement amount data of the gyroscope. A correcting data receiver 32 receives the correcting data transmitted from a known coordinate base. When both receptions of the receiver 31 and the receiver 32 are normal, the received data from the receiver 31 and the correcting data from the receiver 32 are used, and the coordinates of the three-dimensional position of the moving body are obtained. When either of the reception of the receiver 31 or the reception of the receiver 32 is abnormal, the coordinate data of the three-dimensional position of the moving body are obtained (by using) the three-dimensional coordinate data measured at the previous time and the displacement amount data of the gyroscope. The three-dimensional coordinate data measured at this time are stored in a correction processor 33.

2. Description of the Related Art Conventionally, as a method of using a positioning satellite, there is a method of using a positioning device such as GPS (Global Positioning System). In addition, GPS (Global Positio
ning System) is a positioning method in which a plurality of artificial satellites are placed in a state of surrounding the earth, and these radio waves are received to perform positioning. Since radio waves are constantly transmitted from these satellites, there are advantages such as that 24-hour measurement is possible and the position to be measured can be instantly determined. Furthermore, since GPS uses ultra-short waves, the straightness of radio waves is remarkably good, and stable and highly accurate positioning is ensured. Conventionally, as a method of using this, there are single positioning, differential positioning, interference positioning, and the like.

<B> Differential Positioning Two GPS receivers for the above independent positioning are used. One receiver is placed at the reference position (known coordinates). The other one is placed at the measurement position for measurement. According to this method, it is possible to cancel the influence of the ionosphere and atmospheric layer of the earth on radio waves. That is, since the two receivers operate at the same time, both receivers receive the radio waves that have the same influence from the atmosphere or the like. Therefore, since one position is known, the other position can be known.

<C> Interferential Positioning Similar to the differential positioning described above, two GPS receivers are used. In this positioning method, the relative distance is calculated by taking the difference between carrier wave phases of radio waves transmitted from GPS satellites. Therefore, the accuracy is higher than the above two positioning methods, and the measurement can be performed with an accuracy of 10 mm or less.

Embodiments of the present invention will be described below with reference to the drawings. A positioning satellite receiver is arranged in the land-based base station 12 whose position is known, and a positioning satellite receiver and an inertial guidance gyro are arranged on the ship 13. Then, differential positioning is performed by the two positioning satellite receivers to obtain accurate three-dimensional coordinates. However, when the differential positioning is impossible due to radio interference or the like, the present three-dimensional coordinates are obtained using the three-dimensional coordinates measured last time and the displacement amount data obtained by the inertial guidance gyro. By using this method, accurate three-dimensional coordinates can be obtained in real time on the ship.

The receiver 21 is placed in the land base station 12 at known coordinates. Since the positioning radio waves received by the land base station 12 and the ship 13 at the same time are both affected by the same ionosphere and atmospheric layer of the earth, these effects can be canceled. Therefore, the correction data transmitter 22 sends the correction data to the ship 13 by wireless communication. The ship 13 is provided with a correction data receiver 32, and receives the correction data sent. As the communication means, wired communication may be used in addition to wireless communication.

<C> Gyro Displacement Data Processing Device 35 The inertial guidance gyro 34 is widely used as attitude control and guidance device for aircraft and rockets. This configuration
It consists of three precision uniaxial gyros for detecting acceleration and an arithmetic circuit to detect three-dimensional acceleration. The gyro displacement amount data processing device 35 calculates the displacement amount, that is, the moving distance of the ship by integrating the detection data from the inertial guidance gyro twice, and creates the gyro displacement amount data.
The accuracy of the gyro displacement amount data deteriorates due to the accumulation of errors in the displacement amount measurement over a long period of time. Therefore, the displacement amount between the previous measurement and the current measurement is measured and stored in the memory. Therefore, the error does not accumulate for a long time. Moreover, the gyro displacement amount data processing device 3
The displacement amount data obtained in 5 is used when differential positioning is impossible.

For the differential positioning, the correction data obtained from the fixed positioning satellite receiver 21 is used as the correction data receiver 32.
To receive (S4). It is determined whether this reception is normal (S5). If it is normal also here, the differential positioning is performed using the reception data obtained from the mobile and fixed positioning satellite receivers 31 and 21, and highly accurate three-dimensional coordinates are obtained (S6). The obtained three-dimensional coordinate position is output to a display or printer (S7). Since this three-dimensional coordinate position may be used in the next measurement, it is written in the memory in the correction processing device 33 (S8).

When the reception of the positioning radio wave by the mobile positioning satellite receiver 31 is abnormal (S2), or the correction data receiver 3 is received.

Furthermore, the gyro displacement amount data generated between the previous measurement and the current measurement is received from the gyro displacement amount processing device 35 (S10). This gyro displacement amount data and the previously measured three-dimensional coordinates are added to obtain the present three-dimensional coordinates (S6). The procedure thereafter is the same as in the case of normal reception (S7, S8).
