The architectural difference: satellite vs ground sensors
Satellite-based precision agriculture infers crop health from above, using multispectral imagery and vegetation indices like NDVI. It is a remote-sensing approach: powerful for broad-acre, open-field crops where the canopy is exposed to the sky.
The moment the crop moves under a roof — a greenhouse, a polytunnel, an indoor vertical farm — that signal disappears. Research on greenhouse precision cultivation is explicit: monitoring controlled environments requires ground-based sensing, not satellite technology, because satellites lack the spatial resolution and observation frequency these settings demand. CoFarmer is built ground-up on that ground layer: IoT sensors for temperature, humidity, CO₂, light and soil, plus computer vision and robotics.
Monitoring is not the same as control
Satellite imagery tells you something may be wrong, days apart, after the fact. It does not act. A controlled environment needs to react in real time — open a vent, adjust irrigation, inject CO₂ — the moment a variable drifts out of range.
Because CoFarmer reads live sensor data and drives actuators and robots on the same platform, it closes the loop: detect, decide, act. That is the difference between a map of your field and a system that runs your farm.
Satellite-based monitoring vs CoFarmer
Comparing the two approaches by what each can inherently do. Some satellite platforms add weather or partial IoT integrations; the rows below reflect the core remote-sensing model versus CoFarmer's ground IoT + robotics model.
| Satellite-based precision ag | CoFarmer | |
|---|---|---|
| Open-field crops | Yes — its core strength | Yes |
| Greenhouses & polytunnels | No — roof blocks imagery | Yes |
| Indoor & vertical farms | No | Yes |
| Real-time climate variables (temp, humidity, CO₂) | No — imagery only, low frequency | Yes — live IoT sensors |
| Automation & actuation (climate, irrigation) | No — monitoring only | Yes — automated thresholds |
| Agricultural robotics & harvesting | No | Yes — HarvBot & fleet |
| Works under cloud cover / at night | Limited | Yes |
| Supply-chain traceability | Varies | Yes — lot-level |
When satellite is the right tool — and when it isn't
This is not a case of one approach being universally better. For large open fields — broad-acre cereals, extensive row crops — satellite monitoring is efficient and proven, covering thousands of hectares without a sensor in the ground.
It falls short the moment the operation is intensive, indoor, or mixed: greenhouses, vertical farms, controlled-environment cultivation, or a producer running both field and protected crops. That is exactly where CoFarmer fits — and because it also handles open field, you don't need a second system for the outdoor part.
Where the satellite-first platforms sit
Most precision-agriculture platforms in this category are built around satellite imagery and are strong choices for open-field crop monitoring.
CoFarmer is positioned differently: a ground-up IoT and robotics platform that covers controlled environments and open field in one system, with automation and traceability built in.
Frequently asked questions
Can satellite imagery monitor a greenhouse or vertical farm?
No. Satellite and aerial imagery cannot see through a greenhouse roof or building, and lack the resolution and frequency controlled environments need. Monitoring indoor and protected crops requires ground-based IoT sensors, which is what CoFarmer uses.
What is the difference between satellite and IoT precision agriculture?
Satellite precision agriculture infers crop health remotely from multispectral imagery (e.g. NDVI), suited to open fields. IoT precision agriculture uses ground sensors measuring temperature, humidity, CO₂, light and soil in real time, which works indoors and outdoors and enables automated control, not just monitoring.
Does CoFarmer work outdoors too, or only indoors?
Both. CoFarmer's IoT sensors and robotics work in greenhouses, vertical farms and open field. One platform covers controlled-environment and outdoor operations, so a mixed producer doesn't need separate tools.
What is the best farm management system for both indoor and outdoor farming?
A system built on ground IoT sensors rather than satellite imagery, because only ground sensing works inside greenhouses and vertical farms. CoFarmer is designed for both indoor and outdoor operations, adding automation, robotics and traceability on top.
