基于火箭橇的导航系统动态标定测试技术研究

针对北斗系统和惯导系统在现有实验室条件下无法同时模拟真实使用环境下加速度、速度和振动条件，提出使用地面高速火箭橇技术来实现导航系统动态情况下空间位置、速度和时间参数的标定技术。重点讨论了测试系统的组成结构和精度分析，通过这些技术手段来保证高精度导航系统在接近使用环境的条件下测试其精度。这种测试可以在导航系统产品设计、生产制造和交付验收等全阶段实施。

Dynamic calibration technology of navigation system based on rocket sled

Since Beidou system and inertial navigation system can not simultaneously simulate acceleration, velocity and vi- bration conditions in the real application environment under the existing laboratory conditions, the ground high-speed rocket sled technology was adopted to achieve the space position, velocity and time parameters calibration of navigation system in the case of dynamic environment. The composition structure and precision analysis of the test system are discussed emphatically. These technical means is necessary for accuracy testing to ensure the accuracy of navigation system under the conditions close to the cervice environment. This test can be implemented in navigation system product design, manufacturing and delivery.
