Abstract： A technique for testing space object receivers using global navigation satellite system (GNSS) signal simulator of the navigation field is proposed. Its structure consists of two blocks which allow synthesizing the scenario of reciprocal displacement of the receiver relative to navigation satellites and their signals. In the first block, according to the known coordinates of the receiver which are specified in tabular form or analytically, the distances between the receiver and the navigation satellites are calculated as well as their relative velocities. According to these data, the second block synthesizes the signals of navigational travelers with the specified characteristics which are transmitted via the air or cable with a given attenuation to the receiver. This allows testing on the earth receivers for airplanes and space objects under different scenarios of their movement, which not only reduces the risk of problems during the flight, but also avoids significant economic costs. Based on real data obtained by approaching two spacecraft using a simulator, the receiver was tested, which shows the promise of the proposed technology.

摘要:提出了一种利用导航场GNSS信号模拟器对空间物体接收器进行测试的技术。 其结构由两大模块组成， 用以合成接收器与导航卫星的相对位移的场景及信号。 在第一个模块中， 根据已知的以表格形式或分析方法得到的接收器坐标， 计算出接收器与导航卫星之间的距离以及它们的相对速度。 根据这些数据， 在第二个模块中， 将导航旅行者信号和特定特征进行了合成， 这些信号通过空气或电缆传输， 到达接收器有一定的衰减。 这允许在不同的运动场景下对飞机和太空物体的地面接收器进行测试， 既降低了飞行过程中出现问题的风险， 又可以避免巨大的经济成本。 利用模拟器接近两艘宇宙飞船获得的真实数据对接收器进行了测试， 展示了所研究技术的前景。
