Overview of GNSS Reference Station Receiver Market Pricing and Engineering Application Parameters

GNSS reference station receivers are designed for various engineering safety monitoring scenarios. The FT-GS1 model, priced at 6,900 RMB, utilizes differential RTK technology to achieve millimeter-level monitoring accuracy and high stability. It supports multi-protocol transmission and remote data analysis, making it suitable for complex outdoor operational environments.

GNSS reference station receivers are core equipment in the field of engineering safety monitoring. Relying primarily on differential RTK technology, they perform high-precision displacement monitoring, accurately capturing minute displacement changes in structures and geotechnical masses to provide data support for the safe operation and maintenance of various infrastructure projects. The market currently features clearly tiered pricing; domestic civil- and engineering-grade devices offer exceptional cost-performance ratios. Notably, the FT-GS1 GNSS reference station receiver is priced at 6,900 RMB, positioning it as a mainstream model for small-to-medium-scale monitoring projects.

This GNSS reference station receiver excels in millimeter-level precision monitoring. In static differential mode, it achieves horizontal accuracy of ±(2.5mm + 1ppm) and vertical accuracy of ±(5mm + 1ppm), meeting the high-precision monitoring requirements for applications such as dams, bridges, and slope stability. Equipped with a choke-ring antenna and magnetic wave-absorbing materials, the device effectively mitigates data interference caused by multipath effects, significantly enhancing monitoring stability in complex outdoor environments and supporting long-term, continuous field operations.

The hardware configuration meets industrial engineering standards, featuring a wide input voltage range (DC 10V–15V) and a total power consumption of only 0.25W; this low energy consumption makes it ideal for long-term, continuous online monitoring. The device features a compact structure—measuring 360mm in diameter and 163mm in height—and allows for simple, convenient installation without complex construction procedures. It operates reliably within a temperature range of -40°C to +85°C and in humid environments (up to 95% RH, non-condensing), making it suitable for harsh outdoor conditions involving high temperatures, low temperatures, or high humidity.

Regarding data transmission and compatibility, the device supports the Modbus-RTU communication protocol and RTCM3 differential data format. It enables offline displacement calculation at the device level, accurately outputting displacement data for both horizontal and vertical directions. The equipment supports remote monitoring and data analysis, enabling operations and maintenance personnel to remotely view monitoring data and assess operational status, thereby reducing on-site maintenance costs. With strong compatibility, the device seamlessly integrates with various mainstream engineering monitoring systems to facilitate data sharing and fusion; it provides comprehensive, reliable data support for safety early warnings and hazard detection, making it suitable for a wide range of routine safety monitoring projects.
