go2signals go2MONITOR Options

go2MONITOR can be extended with additional functions. To activate these additional functions, usually only a new license file is required.
However, in situations where the software needs to be distributed to multiple computers for performance reasons, PROCITEC support is required for optimal setup.

  • Do not underestimate the need for computing power when 20 MHz have to be processed.
  • It is possible to process more then 20 MHz, but then 10 GbE LAN and high performance computer(s) are needed depending on the number of decoder channels.
  • PMR decoders require an End User Certificate outside EU/Wassenaar
  • PMR requires an EUC outside EU/Wassenaar

MIL, PMR option


Decoder for MIL, STANAG etc. are optional and require End User Certificate EUC) outside Germany.

Please refer to the specifications for the list of MIL decoders.


Decoder for TETRA, TETRAPOL, NXDN, PMR, APCO25 etc. are optional and require End User Certificate EUC) outside EU.

Please refer to the specifications for the list of PMR decoders.

Export Permission (EUC)

For the options MIL and PMR an export permission must be granted by the German authorities. An End User Certificate (EUC) is required. Please download this document here: https://www.procitec.de and send it back to us. You can also find an instruction on the PROCITEC homepage how to fill the EUC. If we can assist, please do not hesitate to contact us.

AMT, Automatic Monitoring & Tasking Option

This AMT option provides user-configurable, mission and task-based automatic signal search. Depending on the tasks, signals are detected, classified, demodulated and decoded automatically.

  • There is a wizard for defining missions, in which the necessary tasks are defined.
  • The results are stored in a database for further evaluation
  • An advanced ResultViewer shows a tabular or graphical representation of the stored data.

After starting a mission, the display shows the spectrogram, FFT and the task activities. The task activities gives a you an overview about the number of signals monitored and the signals waiting to be monitored. Already during automatic monitoring, the results can be viewed and analyzed in the ResultViewer

It is possible to run automatic and manual channels side-by-side

Missions can be defined as "offline processing". This separates the real-time part (recording) from the processing part (narrow-band classification and decoding) and allows faster processing than real-time.

Different tasks require different arrangements of go2MONITOR.

Creating "Missions and Tasks" is supported even in small, mobile monitoring solutions. The task type ‘Live Processing’ is a standard feature in every go2MONITOR version, giving you access to missions and tasks in snapshot mode but the advanced functions require the option "Automatic Monitoring and Tasking (AMT)".

WCL, Wideband Classifier & Input Option

The option “Wideband classifier & input“ extends the signal input bandwidth and the continuous, real time wideband classifier up to 2.4 MHz on HF and 10 or 20 MHz on VHF/UHF.
It is possible to automatically detect, measure and determine modulation type for all signals in the available frequency range. The results are displayed in the GUI and can be used as an input for further processing.

Two additional operating modes for wideband classification are provided:


This mode can be used with all supported wideband receivers. The frequency ranges required by active tasks are processed in a round-robin algorithm. The wideband receiver stays on each fixed frequency range for a defined period of time, performs detection, classification and task actions and then proceeds to the next frequency range.


This mode is possible only if the wideband receiver can provide fast panorama scan function (e.g. IZT R3xxx).
First, a wideband scan is performed in the range covering the frequencies required by the active tasks and fast energy detection is performed. The system checks whether any of the detected frequencies with energy fit to any of the active tasks.

WBR, Wideband Recording Option

With this option go2MONITOR is able record up to 10 or 20 MHz wideband IQ data in real time from the receiver without quality loss on hard-disc. A separate wide band recording component is used.

You can schedule, review and edit your recordings in the recording editor. Select and mark signals or a group of signals to be processed. It is possible to export a single signal or a selection of signals to a new file, usable as new input in go2MONITOR.

The FFT of the recorded spectrum is stored together with the IQ data to provide fast spectrum display and navigation.

For bandwidths >= 20 MHz and longer asuf records, a separate server with a powerful hard disk array (RAID) is normally used.  

WMPC, Wideband Multi Production Channel Option

This feature extends go2MONITOR to produce 16/32 (or up to a few hundred) of channels within the frequency range of the wideband receiver in parallel.

A wideband input (like 20 MHz) requires the automatic, simultaneous processing of many signals. Therefore, the number of processing channels has to be increased. The number of channels depends on the license and the available computing power.
"Offline processing" can be selected for the processing channels. This separates the real-time part (recording) from the signal processing part (narrowband classification and decoding). The recorded files are then processed at approx. 4 times the speed.

HOPD, Hopper Detection Unit Option

This option offers automatic detection of frequency hopping spread spectrum (FHSS) signals in I/Q data streams.

  • Up to 1000 hops/s in VHF / UHF
  • Automatic measured parameters like dwell time, hop bandwidth, hop rate, ...
  • Signal input IZT R3xxx, SIR51xx, SIR21xx, PROCITEC streaming format
  • Requires AMT
  • Requires WCL for BW>1MHz

The Hopper Detection Unit detects frequency hopping emissions inside multiple frequency bands.
The software consists of:

  • several subband processors, each processing one receiver subband
  • a hop combiner that combines the results from all subband processors and places the output in the ResultViewer
  • If the component detects a frequency hopper (FH) it will be reported including the corresponding hop parameters.
