Application of MS302 GNSS Receiver in Hong Kong Reclamation Settlement Monitoring

The settlement monitoring system employs advanced GNSS Receivers strategically positioned at precise locations to meticulously observe and analyze continuous, prolonged alterations in ground settlement. This cutting-edge technology proves particularly well-suited for the comprehensive assessment of settlement patterns in a diverse range of critical infrastructures, including dams, bridges, intricate architectural formations, and roadbeds.

Project Background

The Hong Kong Government has built artificial floating islands through reclamation, where important power generation facilities are constructed. The distinctive geographical context of the floating islands area accentuates the criticality of promptly addressing ground settlement and displacement occurrences. The potential consequences of such events extend beyond mere inconvenience, as they pose a direct and imminent threat to the safety of individuals and the integrity of essential facilities. The vulnerability of this environment becomes even more pronounced when considering the pivotal role that power generation facilities play in sustaining various operations.

Pain Point Analysis

Within the scope of this undertaking, a monitoring station has been established on a reclaimed floating island. This location, while offering unique advantages, presents certain logistical hurdles. Notably, the monitoring point is situated at a considerable distance from the nearest 4G network base station. This geographical isolation introduces the potential for data transmission issues, leading to the loss of crucial monitoring data as it traverses the network.
Compounding this challenge is the presence of a pivotal governmental facility on the island. Given the critical nature of this establishment, it is imperative to ensure the utmost accuracy in detecting even the slightest displacements. Moreover, the need for rapid and effective early warning responses to such deviations is of paramount importance to safeguard both personnel and resources.
In addressing these complex issues, Hi-Target’s compact split-type GNSS receiver emerges as a robust and reliable solution.

Implementation Program

The Hong Kong government has enlisted the specialized expertise of Hi-Target to oversee and ensure the continuous operation of its artificial floating island power generation facilities. Central to this endeavor is Hi-Target’s compact split-type MS302 GNSS receiver, a professional-grade monitoring instrument distinguished by its low power consumption, exceptional performance, and unparalleled precision. This sophisticated equipment is designed to meticulously track both horizontal and vertical displacements of the power generation station by capturing and analyzing the relative variance between its absolute and real-time coordinates.
The integration of the MS302 GNSS receiver is seamlessly complemented by the “monitoring cloud” platform, an innovative system that provides a visual representation of the data collected. This platform employs graphical illustrations to depict real-time resolution results with astonishing millimeter-level accuracy. After a comprehensive evaluation, the project department concluded that the implementation of the Hi-Target GNSS Receiver is the optimal solution. Its exceptional monitoring accuracy, straightforward installation process, and expansive monitoring range make it an ideal choice for overseeing the intricacies of the artificial floating islands.

Workflow

Within the framework of this project, the entirety of the artificial floating island serves as a comprehensive monitoring zone. In line with this overarching approach, a strategically positioned GNSS Receiver base station is established within the designated survey area. This pivotal installation is carefully orchestrated to yield optimal results in the endeavor’s monitoring objectives.
To attain the highest degree of effectiveness, technicians judiciously select a location for the base station that is deliberately distanced from significant water bodies and thoroughfares. This deliberate placement strategy is rooted in the pursuit of creating an environment conducive to precise and reliable monitoring outcomes.

Station 1 & Station 2

Deploying a monitoring station within the same vicinity necessitates a prudent approach to avoid expansive water bodies and roadways. Despite harsh conditions, the compact size and easy installation of the base station offer flexibility in location selection and quick setup due to its integrated antenna and receiver design.
