GNSS signals
Multi-constellation signals illuminate the water surface.
Land-based · Non-contact · Remote
See water levels through satellite signals.
AquaScope uses reflections from GPS, BeiDou and Galileo signals to measure water level from land—supporting coastal, river, reservoir and temporary monitoring without placing sensors in the water.

Measure from land. Maintain from anywhere.
AquaScope Technology Limited is a Hong Kong marine and hydrological monitoring company developing GNSS-reflection instruments and cloud management systems for authorities, infrastructure operators, engineering teams and environmental organisations.
01
Conventional stations can be costly and slow to build.
02
Water depth, waves and geology restrict suitable sites.
03
In-water equipment demands ongoing field maintenance.
04
Remote and temporary missions need faster deployment.
One connected system
From reflected signal to usable water data.
Hardware, edge processing, communications and cloud tools work together as one remote monitoring chain.
Water reflection
Direct and reflected paths form measurable interference patterns.
Land station
An antenna and receiver observe the signal without touching water.
Edge solution
On-site algorithms derive results and retain data during outages.
AquaCloud
Sites, history, health, alerts and APIs in one remote view.

Technology
The water surface becomes the sensor target.
As satellites move across the sky, direct and water-reflected signals form changing interference patterns. AquaScope processes those observations at the station to derive water-level results.
01
Multi-constellation processing
Designed for GPS, BeiDou and Galileo observations.
02
Quality-controlled estimation
Interference features, multi-frequency observations and tidal behaviour are processed together.
03
Resilient edge operation
Local computation reduces transfer needs; buffered data resumes after network recovery.
Applications
Built for places conventional stations struggle to reach.
Coastal & sea-level monitoring
For marine authorities, ports, coastal engineering, surveying and research.
Rivers & reservoirs
For water authorities, reservoir operators and hydraulic engineering teams.
Temporary & emergency monitoring
Supplementary observations during extreme weather, works or station maintenance.
GNSS infrastructure upgrade
Extend suitable CORS sites, towers and coastal infrastructure with water sensing.
Monitoring networks
Centralised multi-site management, alerts and API integration.
