The problem
GNSS jamming and spoofing are a near-daily reality in the Baltic region, breaking aviation, maritime, agriculture, and logistics workflows. Centralized telecom is the failure mode.
Tampere, Finland · Built in public
Baltic GNSS Resilience Module.
A chip-level detector for jamming and spoofing.
Currently in development: an offline, multi-sensor GNSS interference detector and resilient PNT logger for maritime, aviation, and agriculture in the Baltic region. Built in public by Boreacore — an independent, one-person hardware studio in Tampere, Finland.
Current build
Baltic GNSS Resilience Module — a chip-level GNSS interference (jamming/spoofing) detector and resilient PNT logger. Offline by design.
The approach
Multi-band GNSS + IMU + barometer + RF power sensing, running classical sensor fusion and anomaly detection on-device. Logs everything for later analysis. No cloud dependency.
Status
Phase 0 — baseline data collection and classical detector. Custom 4-layer PCB and field validation to follow. Built in public; updates below.
