DGNSS CENTRAL MONITOR

Remote operation of DGNSS infrastructure

The Central Monitor (CM) is a software application developed to provide a complete solution for the utilisation of the DGNSS reference station and integrity monitor for navigation. The application offers full remote control and overview over configuration and status parameters for an unlimited number of DGNSS reference stations and integrity monitor stations.

In a DGNSS network infrastructure, the Central Monitor operates together with a DRS 500 (Differential Reference Station) and an IMS 500 (Integrity

Monitor Station) in a TCP/IP network. Several reference stations, far-field stations and central monitors may operate in the same network.

System features

The main objective of the CM application is to provide tools for remote control, monitoring, data collection and on-line quality control of a network of DGNSS reference stations. The product features a new graphical user interface for real-time operation and system control.

The primary goal of the new HMI (Human Machine Interface) is for the operator to identify and react to critical situations effectively and safely.

Network

The CM application uses a TCP/IP based network infrastructure. Each unit at the reference station sites and far-field monitor sites, has its own unique

IP address and the data is transferred directly from the sites to the Central Monitor. The originating IP address of the data is used to identify the source of the data to the applications and services in the CM application software. To simplify the management and configuration, a Data Router is used to route and encapsulate the data internally in the network, making it possible to concentrate the data into a single TCP or UDP network data stream.

The Windows operating system enables the CM application to interact with a wide range of third party software and solutions such as SQL databases, anti-virus systems, back-up systems, network management systems, network monitoring systems etc.
