Illegal in-vehicle devices
Low-cost “privacy” devices used to avoid vehicle tracking. Their use is prohibited in the EU, yet they disrupt everything nearby — along roads, at ports and around logistics hubs.
Pilot program now open
Positioning that holds under interference.
Rastella is resilient multi-GNSS receiver software for drones, ground robots and vessels — built to keep position continuous and trustworthy, even when the signal is disrupted.
Works with
- GPS
- Galileo
- BeiDou
- PX4
- DDS
Satellite signals reach the ground extremely weak. A small interference source can take position away from an entire area — and every operation that depends on it. Rastella is built to keep it.
Interference
Where interference comes from.
GNSS interference is rarely dramatic. Most of it comes from ordinary, civilian sources — some illegal, many simply faulty.
Faulty or badly installed electronics
Defective amplifiers, antennas and industrial equipment can emit unintentionally in the satellite bands.
Other radio transmitters
Spurious emissions and harmonics from nearby transmitters can fall on GNSS frequencies.
Wide-area interference
Aviation and maritime safety authorities have reported GNSS interference affecting large regions and civil traffic.
Rastella only listens. It is a passive receiver: it never transmits and cannot interfere with other systems.
Technology
See the difference protection makes.
When interference hits, an ordinary receiver loses its satellites. Rastella’s five-antenna array steers its sensitivity away from the source and keeps tracking.
Explore the technology-
Sense
Five antennas observe the sky from five points at once.
-
Suppress
Adaptive spatial processing places a null toward the interference and keeps satellite signals.
-
Deliver
Position and its error estimate go straight to the autopilot, with no gap.

Hardware
Inside Rastella.
Commercially available components, brought together by our own software.
-
1
Five-element antenna array
A controlled reception pattern antenna (CRPA): five antennas on one plate see the sky from five points.
-
2
Multi-channel receiver
All antennas are sampled together, so their signals can be compared with each other.
-
3
Edge computer
An embedded computer runs our receiver software: acquisition, tracking, suppression and navigation.
-
4
Host-system link
Position and error estimate go to the vehicle’s autopilot or control computer as a standard GPS input.
Why Rastella
Advanced protection, without specialised hardware.
Rastella pairs commercially available components with receiver software we build end to end.
Software-defined
Our own receiver software, end to end. Improvements arrive as software updates, not as new hardware.
Processed at the edge
Everything runs on board. No dependence on connectivity.
Multi-constellation
GPS, Galileo and BeiDou tracked together for a stronger solution.
Integration-ready
Position and error estimate arrive as a standard GPS input — on drones, ground robots and boats alike.
