    • An apparatus and method improves the fault tolerance of a rocket or missile guidance system which includes a resonant sensor. When improper initialization is detected, the resonant sensor is reinitialized, repeatedly if necessary, until normal operation is achieved. Improper initialization is detected by comparing data from the guidance system with pre-specified physical limits to roll, pitch, yaw, and/or other features of the flight scenario. Embodiments can also detect a fault condition due to an error signal from a “Built-in-Test” (BIT) module. The initialization sequence initiated by the invention can be identical to the power-on sequence, or it can be a separate, reinitiating sequence. Subsequent resets are initiated as needed, for example until the burn of the rocket fuel and the associated vibrations have ceased and the resonant sensor has been successfully initialized.
    • 一种装置和方法提高了包括谐振传感器的火箭或导弹引导系统的容错性。 当检测到不正确的初始化时，如果需要，可以重复初始化谐振传感器，直到达到正常工作。 通过将来自引导系统的数据与预定的物理限制与飞行情景的滚动，俯仰，偏航和/或其他特征进行比较来检测不正确的初始化。 实施例还可以检测来自“内置测试”（BIT）模块的错误信号的故障状况。 由本发明启动的初始化序列可以与上电序列相同，或者可以是单独的再启动序列。 随后的复位根据需要开始，例如直到火箭燃料的燃烧和相关联的振动已经停止并且谐振传感器已被成功初始化。

    • An accurate and rapid method for characterizing the performance of an APD and setting its operating voltage Vop to an optimal value uses an on-board LED or other pulsed light source to measure APD responses at different operating voltages Vop. An estimated breakdown voltage Vb is determined by comparing the measured responses, and the Vop is adjusted to a new value at a fixed offset from the estimated Vb. The fixed offset is selected according to ambient light conditions, including the presence or absence of light background noise, and whether the sun is partially or fully in the field of view. The method is iterated until convergence, or until a maximum number of iterations is reached. In embodiments, a plurality of APD's having a common Vop can be adjusted, and the Vop is never set below a minimum value VopBW necessary to meet timing requirements for a missile guidance system.
    • 用于表征APD的性能并将其工作电压Vop设置为最佳值的准确和快速的方法使用板上LED或其他脉冲光源来测量在不同工作电压Vop下的APD响应。 通过比较测量的响应来确定估计的击穿电压Vb，并且将Vop调整到与估计的Vb固定偏移的新值。 根据环境光条件选择固定的偏移量，包括是否存在浅色背景噪声，以及太阳是否在视野中部分或全部。 迭代该方法直到收敛，或直到达到最大次数。 在实施例中，可以调整具有公共Vop的多个APD，并且Vop从不被设置为低于满足导弹引导系统的定时要求所必需的最小值VopBW。
