摘要： A method of navigation includes providing an angular rate sensor and a direction-of-gravity reference. The method also includes determining bias error of the angular rate sensor about a vertical axis based on data substantially from the angular rate sensor and from the direction-of-gravity reference. In one embodiment, the first angular rate sensor is moved from a first position around a substantially horizontal axis to a second position around the substantially horizontal axis. The first angular rate sensor provides angular rate data for attitude at the first position and for compass heading at the second position. Data from the first angular rate sensor and from the direction-of-gravity reference is processed with a program for determining a bias error correction for the first angular rate sensor while the first angular rate sensor is in the first position. Bias error correction determined while the first angular rate sensor is in the first position is used to correct angular rate of the first angular rate sensor while the first angular rate sensor is in the second position.

摘要： An electronic system includes a reader and a remotely powered and remotely interrogated sensor transponder. The sensor transponder includes a coil or an antenna, a switched reactance circuit, a processor, and a sensor. The sensor transponder receives power radiated from the reader to the coil or antenna. The sensor uses the power for sensing. The sensor transponder is capable of processing sensor data in the processor and transmitting the sensor data to the reader using the switched reactance circuit. In one embodiment, the receiver coil or antenna is part of a resonant tank circuit which includes an impedance matching circuit. The impedance matching circuit is connected to the receiver coil or antenna to provide greater current to the sensor or other power-using device than would be available to the sensor or other power-using device if the sensor or other power-using device were connected between the first and second end. The impedance matching circuit can be two or more taps to the coil or antenna.
