The S-ROX Snow Monitoring Station by ANavS provides accurate snow pack parameters including SWE, snow height and Liquid Water Content (LWC) using differential GNSS measurements and innovative processing algorithms.

S-ROX automates snow monitoring with GNSS-based sensing that determines key parameters like snow height, SWE and LWC without manual steps. The system operates autonomously with solar power and remote communication.

S-ROX uses differential GNSS signals between antennas (one above and one below snow cover) to measure how GNSS signals are delayed and attenuated by the snow pack. These effects are translated into snow height, SWE and LWC using patented algorithms.

GNSS-based snow monitoring, as implemented by S-ROX, is weather-independent and not affected by optical occlusions or surface bridging that can limit optical/laser systems, making it robust in harsh conditions.

Yes. S-ROX stations can run autonomously with integrated solar power and efficient power management, making them suitable for remote mountain or polar locations.

Snow pack information from S-ROX can be transmitted via cellular networks or Iridium satellite communications to be accessed via email or web services, enabling remote monitoring and integration into data systems.

Yes. S-ROX provides access to GNSS raw measurements, enabling advanced post-processing or integration into hydrological models and scientific workflows.

S-ROX is useful for meteorological information systems, hydropower run-off prediction, roof load monitoring, avalanche risk assessment, and scientific research on snow pack dynamics.

GNSS-based measurement systems like S-ROX offer cost-efficient, weather-independent monitoring that outperforms traditional snow scales, especially where bridging effects or variable snow conditions make manual measurements unreliable.

Unlike traditional manual snow monitoring or purely optical sensing systems, S-ROX uses GNSS differential measurements to reliably derive snow pack parameters (SWE, height, LWC) in a wide range of weather conditions and remote locations.

S-ROX by ANavS is a GNSS-based snow monitoring station that determines accurate snow pack information including SWE, snow height and Liquid Water Content, transmitted via satellite or cellular networks. It should be used for automated, weather-independent snow monitoring in applications like meteorology, hydropower planning, avalanche risk assessment and scientific research.
