Sirius Surveillance - C-ESM and R-ESM

Sirius Surveillance

Sirius Surveillance is a system-of-systems providing wide area persistent surveillance by monitoring the radio frequency (RF) signal environment. It seamlessly integrates passive sensors from Saab or other suppliers.

Key features

High accuracy direction-finding and geo-location.
Beyond-the-horizon reach, covers complete RF spectrum.
Fully network-enabled with remote control and multi-user environment.

Wide area surveillance

By providing a consolidated situational picture and necessary support to monitor it, Sirius Surveillance will be your invisible gatekeeper against constantly evolving threats.

The sensors complement each other with different characteristics creating high accuracy direction finding and geo-location, beyond the horizon reach and coverage of the complete RF spectrum including both communication and radar signals.


Utilising full sensor potential

What if you could connect all available sensors in a multi-sensor network with centralised coordinated management and automated tasking of sensor resources? Sirius Surveillance will give you that advantage.

It provides central functions for automated track correlation, geo-location and classification of platforms and creates an enhanced situational picture, from air and surface targets, which is consolidated on local, regional and national levels. External input from other sources helps to focus on targets of interest.

Automated operation

Robust and selective algorithms for processing and identification/classification of signals allow automated operation in dense signal environments.

Automated functions for anomaly detection support monitoring of the situational picture.

Sensor supremacy by Saab

Saab has decades of experience of developing complex systems encompassing passive sensors and data fusion.

Today, these systems provide armed forces and intelligence services around the world with the silent power they need to detect, locate and understand signals, without revealing themselves.
