IPC: G01C21/16
Filed: 1989-06-23
Abstract: PURPOSE:To accurately determine an error and to improve flight accuracy by storing data in a storage device every time effective variation in Doppler speed appears, and averaging (n) stored data and obtaining the error. CONSTITUTION:Variables epsilontheta, epsilonphi, and epsilonpsi are much less than 1, so an equation 1 is obtained by this measuring method among INS acceleration values nx, ny, and nz, and Doppler speed variation values  VHZ,  VDk, and  VZk between tk+1 when a Doppler speed has effective variation to tk+2. This equation is changed into an equation II, which is rearranged as to epsilontheta epsilonphi, and epsilonpsi to obtain an equation III. Then the data is integrated (n) times and averaged to find errors epsilontheta, epsilonphi, and epsilonpsi in pitch, roll, and yaw component. Further, those variables epsilontheta, epsilonphi, and epsilonpsi are stored automatically on a nonvolatile memory when the power source is off and last epsilontheta, epsilonphi, and epsilonpsi are averaged at the time of a next flight to improve the accuracy more.

Abstract: PURPOSE:To prevent the call of a party station from being interrupted, by disconnecting and turning off the circuit of a station other than a master station or subordinate station while the master or subordinate station is engaged with a line wire. CONSTITUTION:The master station is provided with transmitter-receiver 1 and connected to the subordinate station by radio. The subordinate station is connected to  the line wire via the master station and usable as an interphone. When the master  station is engaged with the line wire, the receiver of telephone set 2 is lifted and  connections with line wires L1 and L2 are made. At this time, circuit connection detecting circuit 19 excits relay RY-4 to disconnect the circuit to the subordinate circuit.
