Sensor Based Spectrum Monitoring System
The LS OBSERVER system consists of various Remote Monitoring Units (RMUs), a Central Control Unit, and software for detailed measurement data analysis.
Mobile, portable, transportable, fixed and airborne monitoring units are available.

How does LS OBSERVER sensor based monitoring system work?
The remote monitoring units (RMU) permanently monitor and record the entire frequency spectrum.
The data measured by the RMU is compressed and stored locally in the device. The operator can access the data locally or from the central control unit. The data transmission between the remote unit and the Central Control Unit requires only limited bandwidth. Advanced filter functionality allows for selective and fast access to the required subset of the data.
With the support of direction finding techniques, such as Time- Difference-of-Arrival (TDoA), Power-Difference-of-Arrival (PDoA) or Angle-of-Arrival (AoA) the operator can spot the location of unwanted or illegal transmitters.
What is so special about LS OBSERVER?
All the recorded spectrum data is compressed and stored locally in the monitoring device.
You don’t need a permanent connection from the remote monitoring unit (RMU) to the Central Control Unit. All the recorded spectrum data is compressed and stored locally in the monitoring device. Raw spectrum observation data is stored for 30 days and compressed, noise-free data for up to two years.
Access the data whenever you need it:
Real-time or recorded data from the past for big data analysis and data comparison to:
- Support spectrum inventory: compare license data in the license database with historical measurement data for continuous spectrum efficiency
- Collect data for evidence-based spectrum policy making and regulation
- In dire need for spectrum? Retrieve the relevant usage information from LS OBSERVER and check whether a licensed frequency band is really used to its full extent. (If not, you may consider re-farming)
- Check on interference that occurred in the past and locate the faulty or illegal transmitter
- Recognize threats immediately for instant law enforcement (military, intrusion on borders, critical sites...)
