Jamming. The signal disappears.
Interference can make a receiver lose the satellite signal. When the position disappears, the crew notices that something is wrong.
GNSS integrity
Can you trust
your position?
You know when the satellite position on your vessel or vehicle cannot be trusted. wepnav compares the signals with independent observations and warns when something does not add up.
AN INDEPENDENT PERSPECTIVEAt sea and on the roadObservation and warningAlarms without a network
01 / The problem
A wrong position can look perfectly right.
Satellite navigation provides both position and time. Chart plotters, AIS, radar overlays, fleet tracking and dispatch use the same data. A wrong position can spread across several systems.
Spoofing. The position lies.
Fake satellite signals can make a receiver report a wrong position with full confidence. It can be hard to notice that the information is wrong.
02 / The product
A sensor on board. A shared picture.
You get an on-board warning and a shared picture for your operation. wepnav detects discrepancies in satellite navigation and makes them visible where decisions are made.
wepnav Sensor
You get an independent check of satellite position on board. A small, self-contained unit uses multiple sensors and sensor fusion to detect discrepancies. Installation works without integration with on-board systems.
wepnav Map
You see where, when and how GNSS is disturbed, in near real time. Sensors report to a shared map. With many sensors, you also get a rough estimate of the area the jammer is in.
wepnav App
You have alarms and position trust on your phone. The app gives you the information you need to assess satellite position, right where you work.
03 / Applications
For operations where position matters.
You get better information for decisions that affect the crew, cargo and on-board systems. wepnav monitors satellite position on vessels and vehicles.
Commercial shipping
The crew knows when satellite position is uncertain. For ferries, pilot services, coastal shipping, fishing and work boats, wepnav provides an independent observation on board.
Authorities and emergency services
A shared picture of interference supports coordination and response. For maritime operations, civil contingency agencies, transport administration, ambulance, rescue and police services.
Position-critical operations
You see when position data needs checking. wepnav provides warnings for operations involving road tolls, tachographs, waste collection and geofenced machines.
Defence
You get independent information when satellite position is uncertain. For military vessels, vehicles and operations that depend on position and time.
04 / Technology and data
Observation runs locally. You choose where the map runs.
You get an independent assessment of satellite position. Multiple sensors provide observations that sensor fusion combines to detect discrepancies.
- Alarms without a network
- You get warnings even without a network. Alarms and logging run on the device, which syncs events when the connection returns.
- Signed events
- You get a record of what happens, where and when. The device classifies events as jamming, spoofing or natural signal loss and signs each logged event.
- Data under your control
- You choose where the map runs: on-prem, in a Swedish cloud or in a cloud of your choice. The service is built on the Copyl platform.
- Developed in Sweden
- wepnav is a product from We Protect AB in Helsingborg. It is designed and assembled in Sweden.
We Protect AB is also behind HAVS Protect (havs.io).
05 / Questions and answers
Frequently asked questions
Can wepnav stop jamming or spoofing?
wepnav detects, warns and documents interference. It warns when satellite position cannot be trusted, but does not block the interference itself.
How do I receive a warning?
wepnav Sensor warns on board. wepnav App shows alarms and position trust on your phone. wepnav Map brings events together in a shared picture.
Does the navigation equipment need replacing?
You use your existing navigation equipment. wepnav is a self-contained unit that observes satellite position without integration with on-board systems.
