Abstract

The article describes recording equipment for reception and preprocessing of global navigation satellite system (GNSS) signals. The base of the data logger is an industrial class receiver capable of a rather high sampling rate of 10 Hz for recording signals. An important option of the data logger is the possibility of transmitting the data in real time, including via wireless links. The technical characteristics of the equipment enabling its stable field operation, including when it is mounted on a moving object, are discussed. The device was tested under field conditions in different modes: as a reference station and on a moving carrier (a vehicle laboratory). In both modes, the recorded information was transmitted online to the data aggregation center of the Institute of Physics of the Earth, Russian Academy of Sciences. In the first case, broadband Internet wire access was used; in the second, via wireless links of cellular providers. Based on the test results, potential areas for the developing of this GNSS data recording system are determined, including improved navigation support of mobile geophysical observations.

具有高采样率的便携式GNSS信号记录系统：现场测试和应用预测

摘要

本文介绍了用于接收和预处理全球导航卫星系统（GNSS）信号的记录设备。数据记录器的基础是工业级接收器，能够以10 Hz的较高采样率记录信号。数据记录器的一个重要选项是可以通过无线链路实时传输数据。讨论了设备的稳定运行技术，包括将其安装在移动物体上时的技术特征。该设备在野外条件下以不同模式进行了测试：作为参考站和在移动的载体上（车辆实验室）。在这两种模式下，记录的信息都在线传输到俄罗斯科学院地球物理研究所的数据聚合中心。在第一种情况下，使用宽带互联网有线接入；第二，通过蜂窝提供商的无线链接。根据测试结果，确定了开发此GNSS数据记录系统的潜在领域，包括改进的移动地球物理观测导航支持。
