摘 要: 目前,提高导航精度的策略主要从信号源的角度出发展开分析,多数研究没有考虑在不更改硬件设计的前提下,仅从算法优化的角度提高导航精度。本文以不改变飞机原有导航系统硬件结构,利用优化算法的方式提高导航精度为目标进行研究,提出一种面向通用航空的基于飞行运动阵列的导航位置算法。该算法可以在不增加硬件成本的前提下,进一步提高导航位置精度,满足对成本敏感的通用航空类飞机需求,尤其适合成本低廉的轻型运动类飞机。本文所述算法在首台国产综合航电产品CR9中得到应用与验证,可以达到研究目标。 |

Abstract: The current strategies for improving navigation accuracy are mainly analyzed from the perspective of signal sources. Most studies do not consider improving navigation accuracy only from the perspective of algorithm optimization without changing the hardware design. This paper proposes a navigation position algorithm based on flight motion array for general aviation, aiming to improve the navigation accuracy by using optimization algorithms without changing the hardware structure of the aircraft's original navigation system. It can further improve the navigation position accuracy without increasing the hardware cost, and meet the needs of cost-sensitive general aviation aircraft, especially suitable for low-cost light sport aircrafts. The proposed algorithm has been applied and verified in the first domestic integrated avionics product CR9, and results show that it can achieve the research goal. |
