WeatherXM H2-LEO Field weather from beyond the last cell tower.

A solar-powered H2 weather station that sends its observations straight to low-Earth-orbit satellites. Built for remote production and research fields where cellular, Wi-Fi and LoRaWAN don't reach.

The problem

The fields that need isolation are the ones without signal.

Hybrid seed production depends on distance. Parent lines are planted away from other fields of the same crop to protect genetic purity, which pushes production and breeding plots into remote valleys, highlands and frontier farmland, in Latin America and beyond, far from towns and far from cell towers.

The weather still decides the season. Without a station on the plot, teams rely on regional models, a distant public station, or a grower's notebook, and lose the local record exactly where the crop is most valuable.

Regional model

Grid cells kilometres wide miss valley heat and local storms.
Distant station

Different altitude, different rain, different season.
Data logger

Data arrives when someone drives out to collect it.

What it's for

The decisions that need weather from the plot itself

Every variable below comes from the station's own sensors on the field, not from a model.

Flowering synchronisation

Male and female parent lines must shed pollen and become receptive in the same window. Growing degree days from on-plot air temperature are how agronomists track and adjust that timing.

TemperatureGDD

Pollination stress

Heat and dry air around flowering can cut seed set. A record from the plot itself shows whether a yield gap came from the season or from the field.

TemperatureHumiditySolar

Isolation integrity

Wind speed and direction during pollen shed help assess drift risk from neighbouring fields and document the conditions behind a purity result.

Wind speedWind direction

Water and irrigation

Rainfall measured at the plot, not at a town station 60 km away, for irrigation scheduling and water-balance records.

RainHumiditySolar

Harvest and seed quality

Rain events and drying conditions ahead of harvest feed decisions on harvest timing and seed moisture.

Grower and audit records

An independent, time-stamped weather record per production field supports contract-grower reviews, trial reports and claims.

How it works

From the plot to your API, with no ground network in between

H2-LEO keeps the H2 sensing platform and replaces the terrestrial radio path with a direct LoRa-based link to Lacuna Space satellites.

01 · MEASURE

H2 sensor suite on the plot. Each observation is signed with device identity and timestamp at the edge.
02 · UPLINK

The station transmits small packets directly to a Lacuna Space satellite passing overhead.
03 · DOWNLINK

The satellite relays the data to a Lacuna ground station, which forwards it to WeatherXM.
04 · QUALIFY

WeatherXM Quality-of-Data checks run on every observation, with its satellite origin recorded.
05 · DELIVER

WeatherXM Pro Portal and API, next to data from your other sites. FACT can verify forecasts against it.

What satellite delivery is good for

✓ Daily agronomic decisions and degree-day tracking
✓ Season-long, per-field weather records
✓ Trial, grower and claims documentation
✓ Verifying forecasts and models at sites nobody measures

Tip: a single LoRaWAN gateway at a farm office with satellite broadband can serve several H2 stations within radio range. That is often the fastest option for plot clusters today.

Pilot program

Start with a few of your hardest sites

H2-LEO is available through pilot projects for organizations with remote production, breeding or research sites. A pilot runs alongside your season and tells you, with your own data, whether satellite stations fit your program.

1

Share your sites

Region or approximate coordinates, crops and season window. Sensitive locations can stay approximate at this stage.
2

Feasibility check

We confirm satellite service, radio regulation and expected cadence for those locations.
3

Agree the data

Variables, reporting needs and how data reaches your agronomy or data platforms.
4

Deploy and evaluate

Stations go on the plots and the results show whether to scale.

Questions

H2-LEO, answered

Can I buy H2-LEO today?

No. H2-LEO is in development with Lacuna Space and available only through pilot projects. There is no retail price yet. If your site has cellular coverage or a farm base with internet within a few kilometres, a shipping station (Pulse LTE or H2 LoRaWAN) can cover it now.

Is the data real-time?

Not in the way cellular is. A satellite IoT link delivers small messages when a satellite is in view, so observations arrive in batches rather than continuously. That suits daily agronomic decisions, degree-day tracking and season records. It is not the right tool for minute-by-minute alarms. Expected cadence and delivery delay for your latitude are confirmed during pilot scoping.

Does anything need to be installed besides the station?

No gateway, SIM, mains power or internet connection at the site is part of the design. The station needs a pole with a clear view of the sky and the sun.

How does the data reach our own systems?

Observations enter the same WeatherXM pipeline as every other station: quality-of-data checks, then delivery through WeatherXM Pro (Portal and API). Agronomy platforms and data teams can pull it over the REST API next to data from your other sites.

Can plot locations and data stay confidential?

Raise it during scoping. Production and breeding sites are often commercially sensitive, so data visibility, sharing and location precision are part of the pilot terms we agree with you.

Which countries are supported?

Satellite service availability and radio regulation differ by country, so we check each pilot location individually before committing. Send us the region or approximate coordinates of your sites.
