Continuously Operating Reference Station Solution

The demand for precise, reliable, and real-time geospatial data is a cornerstone of progress in the digital era, powering applications from cadastral surveying and critical infrastructure development to smart agriculture and deformation monitoring. To meet this need, the Continuously Operating Reference Station (CORS) network has been established as the foundational infrastructure, providing the high-accuracy Global Navigation Satellite System (GNSS) corrections essential to this diverse array of sectors.

A Comprehensive Solution from Leica Geosystems

Leica Geosystems, a global leader in measurement technology and solutions, offers a complete and specialized solution for CORS networks. This solution seamlessly integrates high-performance hardware and intelligent software.

Advanced Hardware

1. Antenna

The Antenna is the “heart” of CORS systems, serving as the gateway for satellite signals. Leica antennas are engineered with advanced technologies to ensure the highest quality signal reception

• Multipath mitigation: Utilizing innovative designs such as choke ring, the antennas effectively filter and reject erroneous signals from the surrounding environment.
• Broad compatibility: They support signal reception from all major operational GNSS constellations.
• Durable design: Built to withstand harsh weather conditions, including rain, wind, dust, and even features lightning protection
• Stable phase centre: The design guarantees a consistent and stable antenna phase center across all azimuths and elevation angles.

2. Receivers

The receiver acts as the “brain” of CORS systems. These devices are integrated with multiple high-end technologies for robust performance.

• Superior GNSS Performance: Equipped with 555 multi-frequency channels, the receiver can track all existing satellite systems simultaneously and even support future signals as they become available.
• Excellent data quality: Advanced signal tracking and automatic multipath mitigation technologies ensure the highest possible data quality.

Versatile Software

In addition to advanced hardware, Leica Geosystems also offers a comprehensive software suite to efficiently operate, monitor, and manage the entire CORS network.    

• Operation and Monitoring: The software is responsible for the precise control and operation of the system.
• Service Management: A secure, integrated portal allows for service subscriptions and provides administrators with tools for managing and monitoring services.
• Quality Assurance:  It includes dedicated tools for analyzing and ensuring the quality of the entire network.

In Vietnam, the Leica Geosystems’ CORS solution has been successfully deployed in several provinces. The current network consists of 65 CORS stations nationwide, primarily using advanced receiver and antenna technology. This network continuously provides high-precision positioning data, effectively supporting a multitude of industries.
