    • A method and system for azimuth measurements using one or more gyro sensors is disclosed. The method includes acquiring a first data from each of the gyro sensors with an input axis aligned to a first angular orientation and acquiring a second data from each of the gyro sensors with the input axis flipped to a second angular orientation opposite to the first angular orientation. An earth rate component at the first angular orientations is determined based on a difference between the first data and the second data to cancel out bias of each of the gyro sensors. The method may include acquiring a third data of the gyro sensor with the input axis aligned to the same angular orientation as the first angular orientation. An average of the first data and the third data may be used instead of the first data for determining the earth rate component.
    • 公开了一种使用一个或多个陀螺传感器进行方位测量的方法和系统。 该方法包括从每个陀螺传感器获取第一数据,其中输入轴与第一角度取向对准,并且从每个陀螺仪传感器获取第二数据,其中输入轴被翻转到与第一角度取向相反的第二角度取向 。 基于第一数据和第二数据之间的差来确定第一角度取向处的地球速率分量以抵消每个陀螺仪传感器的偏置。 该方法可以包括获取陀螺仪传感器的第三数据,其中输入轴与第一角度取向对准与相同的角度取向。 可以使用第一数据和第三数据的平均值而不是用于确定地球速率分量的第一数据。
