Abstract

The method, which is suitable for the technical field of global navigation satellite systems, provides a PXI-based extensible continuous operation reference station and a GNSS foundation enhancement system. The continuous operation reference station comprises a case, a master control data processing board card, an optical fiber access board card, a wireless or wired internet access board card, a firewall processing board card, a power management board card and at least two GNSS board cards, wherein the master control data processing board card, the optical fiber access board card, the wirelessor wired internet access board card, the firewall processing board card, the power management board card and at least two GNSS board cards are arranged in the case. The power management board card isused for providing direct-current power; the master control data processing board card collects observation data through the GNSS board card. Data are transmitted through the optical fiber access board card, the wireless or wired network port board card and the firewall processing board card, control and state monitoring are carried out on the optical fiber access board card, the wireless or wired network port board card, the firewall processing board card, the power management board card and the GNSS board card, and an abnormal state is reported. According to the invention, all devices are integrated in the case, so that the system power consumption is reduced, the cost is lowered, the system is simplified, and fault points are reduced.

Description

technical field [0001] The invention belongs to the technical field of global navigation satellite systems, in particular to a PXI-based scalable continuous operation reference station and a GNSS ground-based augmentation system. Background technique [0002] At present, the construction of platforms such as intelligent driving, drones, precision agriculture, and the Internet of Things in China is in full swing, and various system applications are inseparable from accurate spatial location information.
