Fusing Copernicus Sentinel-2 satellite observation, 30-year historical rainfall baselines, and certified agronomist ground truth—delivered directly to 2G feature phones via Africa's Talking USSD.
Why single-source weather apps fail in Rwanda: satellite data needs ground-truth validation, and warnings must reach farmers who only have 2G phones.
Ingests Open-Meteo multi-model ensembles (ECMWF & GFS), Copernicus Sentinel-2 10m NDVI vegetative canopy indices, and GloFAS topsoil root-zone moisture (0–7cm).
Certified district agronomists and cooperative extension officers submit GPS-tagged crop health and localized flood reports. Enforces optimistic concurrency locks to eliminate race conditions.
A sub-second telco webhook endpoint serving all 5 provinces and 30 districts. Strictly formatted for GSM ≤ 160-character screens with dual Kinyarwanda & English menus.
Dial the simulator keypad below or use 1-click quick presets to see real live API responses from /api/ussd.
This simulator communicates directly with our live production webhook at /api/ussd. Experience exactly how a smallholder farmer with a basic $15 Nokia phone accesses district rainfall, 30-year anomalies, and soil moisture anywhere in Rwanda.
Every screen is engineered to prevent telco pagination fees and text fragmentation on 2G screens.
Dual Kinyarwanda/English prompts (Hitamo Intara, Ubuhehere) ensure effortless smallholder adoption.
Select any of Rwanda's 30 districts to inspect localized precipitation, vegetative canopy, and 30-year anomalies.
Ijuru Signal applies deterministic, multi-source sensor fusion without ever fabricating unverified disaster alarms.
Aggregates hourly probability (%) and liquid accumulation (mm) from ECMWF and GFS ensembles calibrated to district centroid altitude.
Compares current 5-day rainfall against CHIRPS 1991–2020 normals to detect unseasonal "false starts" that destroy early seeds.
Monitors 0–7cm topsoil moisture and ET0 evaporation. Root-zone saturation above 70% with heavy rain flags flash flood and landslide hazard.
Never issues synthetic or unauthorized warnings. Retains observation timestamps, processing versions, and attributes Meteo Rwanda advisories.
In Rwanda, over 85% of farmers practice rainfed agriculture. Sowing crops during a temporary August shower that dries up days later can lead to total crop failure. Ijuru Signal empowers farmers, extension workers, and cooperatives to make evidence-based planting decisions.
By comparing rainfall against 30-year CHIRPS baselines, farmers wait for true seasonal onset before sowing expensive hybrid seeds.
Agricultural insurers use our historical anomaly logs to verify drought claims in 24 hours without contentious manual site audits.
Extension officers use our offline-capable field check review system to calibrate satellite models against on-the-ground crop health.
Combining expertise in Earth Observation, telecom gateways, distributed systems, and Rwandan agronomy.
System architecture, dual persistence design (Postgres 18 & SQLite), and technical deployment on ThalesOps.
Sentinel-2 NDVI ingestion, CHIRPS 30-year climate anomaly integration, and Rwanda 30-district microclimate modeling.
Africa's Talking USSD gateway engineering, GSM 160-char protocol optimization, and Kinyarwanda dialogue flows.
Ground-truth field check workflows, agricultural cooperative partnerships, and crop calendar calibration.
