基于GPS/DR的无人机导航定位方案研究

The Study on Positioning and Guidance Scheme for an Unmanned Air Vehicle Based on GPS/DR

为提高无人机 GPS 绝对定位时的精度。文中提出了波。该方案具有对硬件要求低、良好的费效比等特点,仿真证明该方案定位精度高而且有效地解决了无人机机动时的适时定位问题。

To improve the precision of GPS positioning for UAV.This paper propose a scheme by Adaptive Kalman Filter.GPS and accelerometer equipped on the UAV are used.The measured values (position and velocity)for Kalman Filter are calculated on acceleration provided by accelerometer during twice update of GPS.The scheme has many virtues,such as having less requirement for hardware and a favorable ratio of cost of performance.The result of Simulation testifies that the scheme improved the precision of positioning for...
