Take control of
the airspace
A counter-drone platform built on the ELRS protocol — from a developer-grade signal analyzer to deployable enterprise jamming arrays. One firmware. Three product tiers. Zero compromises.
Drones are everywhere.
It's a matter of time before they reach their goal.
We see them before they arrive.
Smart electronic warfare.
eShield is hardware-agnostic firmware. It runs on commodity ELRS transceivers — RadioMaster Nomad, BAYCK Gemini Dual Band, and others — and turns them into a protocol-aware counter-drone toolkit. Where conventional EW blasts noise across the band, our system understands what it's hearing and acts surgically.
- Detect drone presence the moment a link comes up
- Decode the live control channel — frame by frame
- Jam selected channels only — no collateral noise
- Takeover: hijack the link and steer the drone
Look inside the protocol.
A single Nomad device, reflashed with the eShield analyzer firmware, becomes a packet-level inspector for ExpressLRS traffic. For RF engineers, security researchers, and ELRS contributors who need to see what's actually on the air.
- Live packet capture across all ELRS frequencies
- Channel-hop tracking with timing analysis
- Telemetry decode and field-level inspection
- SDK available for Android, Python, C/C++
Pocket-scale defense.
One base device, custom housing, integrated battery. The eShield Personal is the smallest deployable counter-drone unit in our line — built for individuals operating where threats are close and reaction time is short.
- Single-handed operation, only 300 g
- 8+ hour battery life on standby
- Effective against ELRS-controlled drones at close range
- USB-C charging, status LED ring
Cover the perimeter.
When one device isn't enough. Enterprise units coordinate four nodes through a single controller, scaling effective range and azimuth coverage for fixed installations and critical infrastructure.
- Multiple targets tracked in parallel
- More frequencies covered simultaneously
- Directional antennas for range and bearing
- Coordinated jamming and takeover across nodes
Pick your tier.
Same firmware. Same protocol coverage. Different scale.
