For improving the performance of differential ring laser inertial navigation system, fast and high accurate pulse signal counting technology is needed for gyroscope.

为了提高四频差动激光陀螺惯性导航系统的性能，需要应用快速高精度的陀螺脉冲信号计数技术。

The so called indirect integral operation means that Eular angles can be gotten from the direction cosine matrix which is received by the integral operation of quaternions or direction cosine.

飞行器导航中，姿态角的获取可以通过直接或间接的积分运算求得的，所谓间接获取即是指通过四元数或方向余弦的积分运算求得姿态矩阵，再从姿态矩阵中提取姿态角。

The calculation of initial alignment direction cosine matrix between SINS body frame and navigation reference frame is expanded into three parts:(1) the DCM between i0 frame and n frame is easily obtained via local geographical coordinates and initial alignment time;(2) by expressing SINS specific force equation in b frame and by the aid of external velocity log, the constant DCM from i(subscript 0) frame to i0 frame is achieved;(3) attitude updating using gyro samples gets the DCM between b frame and i(subscript b0) frame.

将捷联惯组坐标系与导航坐标系之间的初始对准姿态矩阵的实现分解为三步骤：(1)通过地理位置和初始对准时间求解i0系至n系的变换矩阵；(2)通过惯导比力方程变形，引入刚速仪速度辅助，求解从i(下标 b0)系至i0系的常值变换矩阵；(3)使用姿态更新算法实时计算b相对于i(下标 b0)系的变换矩阵。

On moving base, a new initial alignment algorithm for strapdown inertial navigation system is proposed. In the algorithm, two special inertial frames, the initial-time inertial frame (i0 frame) and the initial-time SINS body inertial frame (ib0 frame), are defined and are selected as calculation reference frames, then, the calculation of initial alignment direction cosine matrix is expanded into three parts:(1) the DCM between i0 frame and the navigation frame will be easily obtained via local geographical coordinates and initial alignment time;(2) attitude updating using gyro samples gets the DCM between SINS frame and ib0 frame;(3) by explaining SINS specific force equation in SINS body frame, the relation between velocity log, accelerometer measurement and gravity acceleration is established to achieve the constant DCM from ib0 frame to i0 frame.

在运载体运动情况下，提出了一种适用于捷联惯导系初始对准的新算法，该算法以惯性空间为参考基准，即建立了初始时刻惯性坐标系（i0系）和初始时刻捷联惯组惯性坐标系（ib0系）两个惯性坐标系，将初始对准姿态矩阵的实现分解为三部分：（1）通过地理位置和初始对准时间求解i0系至导航坐标系的变换矩阵；（2）使用姿态更新算法实时计算捷联惯组相对于ib0系的变换矩阵；（3）通过惯导比力方程变形，获得测速仪辅助测量、加速度计输出和重力加速度之间的关系，从中可以求解出从ib0系至i0系的常值变换矩阵。

Early radio direction finder is a radio navigation equipment.

无线电测向仪是早期的一种无线电导航设备。

A modern direction finder, as was then used for radio navigation in large passenger ships, used a steerable ring antenna to determine the airship's position from any two radio transmitters either land or ship-based.

一个现代化的方向搜索，因为当时使用的无线电导航大型客船，使用环形天线可操纵的飞艇，以确定的立场，任何两个无线电发射机或船舶或者土地为基础的。

The software can solve this problem, because it will be key figures for the nine direction navigation key mapping.

该软件能够解决这个问题，因为这将是关键的数字为9方向导航键映射。

If you don't, online directions are free.

如果你不知道，网上的导航可是免费的。

The mechanically dithered ring laser gyro is playing a more and more important role in inertial strapdown systems in our country.

采用机械抖动偏频的激光陀螺在国内的捷联惯性导航系统中正起到越来越重要的作用。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
