Just seen an interesting transmission appear on your spectrum, but now it’s disappeared? Need to know where it came from, but you weren’t running a geolocation task at the time? Tough luck, it’s gone forever. If you’re lucky, you can sit there staring at your screen and it might pop up again.
Sounds ridiculous? That’s what we thought, which is why we developed our geolocation in post-processing capability, so you can perform TDOA geolocation retrospectively on recorded spectrum data. Geolocation in post-processing adds flexibility to your spectrum monitoring missions, enabling applications previously unachievable.

Remote autonomous monitoring
For example, you might want to leave a Node or an RFeye Stormcase in a remote area to operate autonomously. If there’s no network infrastructure available to send spectrum data over IP, then real-time geolocation will not be possible. However, the Node can be left to record spectrum data which is then retrieved later for geolocation in post-processing. In many scenarios not requiring a real-time geolocation and response to detected signals, this is the perfect solution to get around infrastructure constraint issues.
If Nodes are being left for long periods of time and you don’t want to end up wading through hours or days of uneventful recorded data, you can also use our triggered record capability. This allows frequency masks to be set up so that only signals of interest are recorded. You might then be left with just a few minutes of interesting signals which you can analyze and geolocate – a much lighter and less tedious workload than if you had to search the data for them first.
Portable RF Spectrum monitoring
As well as using a fixed Node to record snippets of data for post processing, you can also use an RFeye Stormcase. The key advantage of the Stormcase is its mobility. The portable RFeye Stormcase can be preconfigured to record on trigger and then left in a remote location. At the flick of a switch, data can be autonomously written to disc without any operator input. Once the mission is over, the Stormcases can be retrieved and any signals recorded can be geolocated in post-processing.
