摘　　要：针对目前GNSS定向仪初始化时间长、定向精度低的问题，推导了GNSS双天线定向的观测方程，提出了一种快速解算整周模糊度的方法。采用Trimble公司生产的BD982OEM板研制出一套GNSS双天线快速定向仪系统，根据用户需求编写了一套功能齐全的定向系统软件。结果表明，该定向仪系统能够快速初始化，同传统GNSS定向仪相比，其初始化时间明显缩短，定向精度明显提高。In order to solve the overlong initialization time and low direction precision problems of current GNSS direction finder, a GNSS dual antenna directional observation equation is deduced and a fast integer ambiguity resolution method is put for- ward in this paper. A GNSS dual antenna rapid directional instrument system is developed using the Trimble BD982 OEM board, and a set of full -featured orientation system software are programmed based on user requirements. The experiment results show that the directional system can realize fast initialization. Compared with traditional GNSS direction finder, the initialization time is shortened significantly and directional precision is improved obviously.
