RayX is building a trustworthy measurement layer for farmland, starting with crop yield — so every field can be measured, compared and audited from space.
Official yield figures arrive long after the crop is cut, and satellite estimates rarely show how they were made. RayX can issue weekly from May — field by field, with intervals, and a record that can't quietly change.
2026 season · The 2024 UK final was published on 12 December 2024 — and official figures are themselves revised
One consistent, independent record of what land has produced, is producing and could produce — whoever farms it, and whatever records they keep.
Field Passports, plus in-season forecasts for GB wheat and US maize, validated against harvester yield data. Open them, explore, then tell us what you'd need.

How has this field actually performed?
Season-by-season yield for every field, how stable it is, how far it sits from comparable fields nearby, and the likely reason — management, weather, rotation, slope, margins or soil.
What will this field, county or country produce?
Winter-wheat area, yield and production every week of the season — from a single field up to Great Britain, each with a 90% band that narrows towards harvest.
How much corn is coming, and from where?
Corn area, yield and production across the core Corn Belt — Iowa, Illinois, Minnesota, Missouri and Wisconsin — from state and county down to the field.
Put field-level yield history and forecasts inside the agronomy, farm-management and decision-support tools your customers already use.
An independent, consistent view of what land has produced and what it is likely to produce — and the evidence to show why.
Every value links back to the satellite observations behind it, with a dated record of each issue.
01A 90% band on every estimate, narrowing as the season firms up.
02Checked against harvester yield data at field level.
03One consistent method across every field and season — even where farm records are incomplete.
04RayX is early, and the partners who join now shape what gets built next. If one of these is you, we'd like to talk.
Agronomy and farm-software platforms to evaluate Field Passports across their fields. Grain buyers, processors and traders to run a season of wheat or maize forecasts against their current view. Lenders and land agents to test field history on real decisions.
Discuss a pilot →Share combine yield maps and field records to sharpen our validation. In return, you get free field reports and in-season forecasts for your farm.
Get involved →Environmental-science, crop-research and knowledge-exchange partners for collaborative R&D and on-farm trials.
Propose a project →We're preparing our first round and welcome conversations with agri-food, climate and Earth-observation investors.

Join the test list →RayX is a UK agricultural intelligence company founded by Dr Feng Yin and developed from nearly a decade of Earth-observation research at UCL and the National Centre for Earth Observation (NCEO).
Built on satellite Earth observation, it gives an independent view of what land has produced, what it is likely to produce, where performance is persistently strong or weak, and how weather and management shape the outcome.
Research heritage in Earth observation and crop science.
Open-source atmospheric correction developed by our founder — peer-reviewed and assessed in the international ACIX-II intercomparison.
Partners on the 2026 GB winter-wheat forecast, produced with UCL and NCEO.
Clarity in every signal · Confidence in every decision
A pilot, farm data, a research project or an investment — the first step is a conversation.
