WeatherXM H2-LEO
Weather observations beyond terrestrial coverage.
The WeatherXM H2-LEO is an experimental, direct-to-satellite weather station developed in collaboration with Lacuna Space. Based on the proven H2 hardware platform, the H2-LEO transmits meteorological observations directly to Low Earth Orbit (LEO) satellites — delivering ground-truth weather data from remote study plots, isolated ridgelines, and research corridors without terrestrial cellular, Wi-Fi, or LoRaWAN coverage.
Architecture
How H2-LEO Works
From physical ground measurement to orbital relay and verified data delivery.
Edge Sensing & Origin
Same meteorological sensor array as the H2 station. Measures temperature, humidity, pressure, wind speed, wind direction, solar radiation, UV index and precipitation. Sensor data is signed with device identity and timestamp at the edge.
Direct satellite uplink
An optimized antenna and satellite-compatible radio transmit observation packets directly to passing Lacuna Space LEO satellites in Low Earth Orbit. No ground gateway, cellular tower or internet connection required.
Orbital Relay & QoD
Lacuna Space ground stations downlink the satellite telemetry and forward it to WeatherXM. The observation passes through server-side Quality of Data algorithms and carries orbital-origin metadata.
Enterprise APIs & FACT
Delivered via the standard WeatherXM REST APIs, WeatherXM Pro portal and FACT system — bringing verified ground observations from places where weather was previously unmonitored.
Developed with Lacuna Space
Lacuna Space ↗ operates an open, interoperable satellite IoT network using LoRaWAN standards. By pairing WeatherXM's field-tested meteorological sensing hardware with Lacuna's Low Earth Orbit satellite infrastructure, the H2-LEO pilot evaluates direct-to-satellite weather sensing for extreme off-grid and remote environments.
Pilot Program & Enterprise Inquiries
The H2-LEO is currently in pilot testing and is not available for direct retail purchase. Organizations with remote, off-grid or maritime monitoring requirements are invited to apply for pilot deployments.
