| 摘 要： | 天文定向是以观测天体来确定地面目标方位角的高精度自主定向方法。但是，传统的天文定向设备繁重，无法满足机动应用。针对这一问题，利用电子经纬仪和内置GPS OEM板的掌上电脑，建立了新型便携式天文定向系统，提出了将时角法模型推广到太阳和任意恒星定向的新思路。测试结果表明该系统精度高、速度快，能满足快速机动定向的需求。 |

| Abstract: | Astronomical orientation is an independence high precise orientation method, which works by observing the stars. However, heavy traditional equipment for astronomical orientation can＇ t meet mobile application. To solve the problem, a new portable astronomical orientation system is designed which consists of an electronic theodolite and an embedded GPS card PDA. In this system, the method by hour angle is extended to the sun and any star. Testing results indicate that the new system is precise and fast, and it can be used for mobile orientation. |
