Overview

New threats demand superior information, acquired and analysed from all potential sources. The increasing number of emissions and the rising density of cryptic signals produced by new or modified modems demands an highly automated approach and the use of sophisticated demodulation and decoding systems.

go2MONITOR is a modular all-in-one software solution for receiver control, classification, demodulation, decoding and recording of HF, VHF and UHF signals.

go2MONITOR has an easy to use, automated interface for monitoring tasks. One single tool provides all the necessary processing steps - classification, demodulation, recording and decoding - in a fully integrated environment.

go2MONITOR supports the operator to monitor up to eight signals in parallel. Its automatic buffering of the complete wideband signal input allows easy switching to new signals without loss of information.

Known signals can be monitored easily thanks to the included station list and extensive decoder library. The available production channel will automatically process classification, recognition and decoding.

The Solution for...

COMINT, SIGINT, Signal Corps, Homeland Security

go2MONITOR is a standalone application and is perfect suited for all bodies in the defense and security organizations.

EW

Operations are executed in an increasingly complicated electromagnetic spectrum environment. The need for forces to have unimpeded access to and use of the electromagnetic environment demands on continuous information about the actual situation.

Mission Planning

Advance commandos, need a small and automatic system to pickup the required data necessary to do a successful mission planning at home.

Spectrum Monitoring

We provide Telecom Regulators (ITU) with the information on how the radio spectrum is utilized and if necessary the data to identify intrudes by monitoring part of the traffic.

System integrators

A remote control interface is available and provides all the function required to integrate go2MONITOR in to your application. Your product will be earlier on the market and you don’t bear the risk and costs of the development of an own decoding software.
Ask us if you need further details regarding the ICD (low level interface documentation) or the C++/Java API's.

Use Cases

Determination of frequency allocation

go2MONITOR gives you an overall survey of a defined part of the radio spectrum. The system runs in automatic mode, searches for all signals in a predefined frequency range and stores the results from the classification (frequency, modulation, symbol rate etc.). Rules can be defined to control the behavior of the system.

The system runs in automatic mode, searches for all signals in a predefined frequency range and stores the results from the classification (frequency, modulation, symbol rate etc.). Rules can be defined to control the behavior of the system.

Automatic search and decoding of known signal types

go2MONITOR searches in predefined frequency ranges for decodable signals. Found signals are classified, technical parameters of the signals are evaluated, decoded and all the output (text, audio, binary data, metadata) is stored in the database. Rules can be defined to control the behavior of the system.

Automatic search and recording of unknown signal types

go2MONITOR searches in a predefined frequency range for undecodable signals. Found signals are recorded digitally for more in depth analysis. Rules (e.g. burst duration, bandwidth) can be defined to control the behavior of the system.

Automatic frequency monitoring

Simply connect an SDR and start decoding the most advanced protocols
go2MONITOR monitors a list of predefined frequencies. If a transmission starts and if decoding is possible, then the output of the decoder is stored. If no decoding is possible then the signal is recorded. Rules can be defined to control the behavior of the system.

Manual online monitoring of frequencies

go2MONITOR is controlled by the operator. The operator tunes the receivers, selects a signal, uses the classifier or manually starts a decoder. Output is stored. Visual tools like FFT, spectrogram, waterfall, zoom and cursors can be used from the operator. Live-audio is also available for feedback.

Recording frequency ranges

go2MONITOR records the IF in a selected range. Manual mode is possible but also rules can be defined to control the behavior of the system.

User specific actions, control, interface

The implemented Python scripting engine provides all the function if you have to do some specialized automoatization that is not supported "out-of the-box".

Features

Multi-channel wideband signal monitoring

go2MONITOR simplifies radio monitoring in a unique way. Just select signals of interest in the wideband input display; they are cut out by Digital Down Conversion (DDC) for further operations in the production channels. There, the detailed narrowband analysis of the signals is performed. Up to eight signals are simultaneously analysed and decoded. Detected activities are classified, the protocols are evaluated, decoding is started and the output is stored. The operator acts only as a supervisor.

  • Signal selection. Mark signals of interest in the wideband displays spectrogram or drag and drop results from the snapshot classifier to define production channels input.
  • Production channel. The selected signal is assigned to a production channel (using internal DDCs) for in-depth signal processing.
Production Channels

The result display shows the collected results in detail and can be configured using the Extensible Style sheet Language (XSLT). Up to eight production channels can be used in parallel in manual mode, several hundreds in automatic mode.

  • Classification. A continuous classification takes place on the selected signal and the modulation parameters are evaluated, displayed and stored in the database.
  • Decoding mode. The production channel is set fix to a decoder/modem without automatic protocol detection. Output and modulation parameters are evaluated, displayed and stored in the database.
  • Recognition and decoding mode. An assigned signal will be decoded automatically. The signal is checked against a list of decoders and the best match selected for decoding. These operations are buffered to avoid any data loss.
  • Classification, recognition and decoding mode. The signal is classified and the list of decoders is automatically reduced according to the modulation type and all other parameters like symbol rate, shift, and number of tones etc.
Operating Modes

The selection of signals for analysis, recording, classification and decoding can be automatic or manual.

  • Automatic mode: Based on set of rules defined by the operator, the product will automatically search for signals, demodulate, decode and store the results. This leaves the operator free to concentrate on the unknown signal types that emerge.
  • Manual: The operator selects manually a signal in the go2MONITOR GUI and then manually or automatically let the system select the correct decoder to decode the signal.
Modulation and modem type Classifier

The go2MONITOR software contains a high performance wideband classifier with unique functionality:

  • Detection of all signals in the wideband input frequency range
  • Wide- and narrowband modulation type classification
  • Wide- and narrowband modem/protocol classification for specific modem types
  • Automatic signal tracking (start/end, modulation type change, …)
  • Detailed signal parameters measurement
Automatic Recognition and Decoding

The production channels use configurable lists of decoders/modems for automatic protocol detection. The best match is selected for decoding. The signal is demodulated, decoded and the results are displayed in the result view. The decoder modem lists can be configured, loaded and saved. The decoders/modems lists can be tailored according to the monitoring task.

Signals of interest can easily be added to an integrated station list. Entries in the station list can be assigned to production channels by using drag & drop or the context menu.

  • Reliable recognition, demodulation and decoding of signals
  • Detection and recording of speech signals
  • More than 200 protocols available, permanently extended
  • Processing of signals without loss (getting the first bit)
  • Extraction of information about the transmission protocol, meta data, time-stamp etc.
  • Signal decoding down to the content like text, audio, binaries etc.
  • Storing the output in a database and files
  • Extendible by the customer (Universal Demodulator, Decoder Description Language)
  • Protocol aided soft-decision demodulators and decoders

As an outstanding feature the go2MONITOR/go2DECODE software enables the user to extend the existing decoder library by using go2DECODE. Using its integrated decoder development features, its easy to develop new or modify existing decoders and use them together with the integrated universal demodulators.

Wide- and narrowband Recording

go2MONITOR provides functions to record wide- and narrowband IF signals without loss of quality. Start and stop of recording can be controlled from the channel processing part of the GUI or automatically controlled by signal parameters (modulation parameters, energy, etc.).

  • Loss-less IF wide- and narrowband signal recording
  • Additional wideband spectrum recording for fast signal review
  • Automatic scheduled recording
  • Automatic recording triggered by signal parameters (modulation parameters, etc.)
  • Replay of recordings for later analysis and decoding
Easy to use Wideband GUI

All modules, functions and features are controlled from the go2MONITOR GUI. The GUI is modular and flexible and allows easy adaptation to specific requirements and contains the following parts:

  • Live signal monitoring
  • Extraction of narrowband channel
  • Signal modulation and modem classification
  • Interactive demodulation and decoding
  • Live audio
  • Wideband and narrowband recording control
  • Task scheduler and monitoring (of all executed jobs)
  • Replay of IF recordings
  • Result storage and postprocessing
Multi Wideband Signal Inputs

go2MONITOR is ready to run multiple wideband inputs side-by side in one application. The wideband inputs can be connected to the same receiver (for example multiple streams from one PLATH SIR 511X receiver) or to different receivers from different manufacturers parametrized on different frequencies.

Tabs are used to show multiple receivers wideband input (to safe screen space). Additional  receivers input can be displayed side by side.

For signal decoding, the production channels can be set independently to any receiver input, giving full flexibility.

Typical scenarios:

  • Work with multiple receivers connected to different antennas (different locations, directions, polarisation, etc.) and select the best one for decoding.
  • Monitor HF and VHF/UHF at the same time using different receivers.
  • Monitor multiple frequency ranges at the same time and use the available decoding channels according to your requirements.
  • Simultaneous decoding/recording from one receiver and additional playback of recorded files. So even during live monitoring you can work with recorded files in parallel.
ResultViewer

During live monitoring or in automatic mode all results are stored in a data base for later result analysis and export. With the ResultViewer you can have a filtered view even over the results of some weeks. Many postprocessing features like result editing, signal replaying, data and file export, IF audio listening etc. are outstanding software features.

  • Browser or graphical result display
  • Showing all detected emissions, classifier results, decoder output etc.
  • Results filtering for time, frequency, modulation parameters, protocol, text etc.
  • Audio player
  • Results export
  • Different formatting options for text or binaries
  • System and signal location map (interface to DF system necessary)
Remote Control, Interface

go2MONITOR offers various functions to exchange data with other applications or systems and offers full remote control capabilities. Running without user interface the software can be used as backend signal monitoring core integrated in other systems.

  • Remote Control of the software via TCP/IP
  • Directly access of all result files stored in the file system or SQL based database
  • Operating without GUI for backend integration

Decoders and Demodulators

  1. MIL and PMR decoders may need an End-User-Certificate (depending on the country of the user)
  2. Automatic sideband detection can be achieved via two modems set to inverse sidebands
  3. A time gap between message bursts and acknowledge burst must be detectable
  4. Separation of slow selcall types cannot be guaranteed
  5. Slow multitone modems are recommended to operate with fixed nominal frequency

Our set of standard, military,PMR and SAT decoders is subject to continuous development.

  • Different modulation types are coloured differently

… and all signals are classified automatically.

  • Production channel

  • Signal selection by drag&drop

Once the signal is acquired from the wide-band display, it is moved by Digital Down Conversion (DDC) to a production channel. Here the detailed narrow band analysis of the signal can be performed.

  • Signal overview

  • Decoder status

  • Decoded Text

  • Decoding and data transmission

  • Decoding and recording (morse)

  • Classification and live listening (voice)

Detected activities are classified, the protocols are evaluated, decoding is started and the output is stored. Up to eight production channels can work in parallel.

go2MONITOR works as fully automatic monitoring solution using missions and tasks. A wizard is provided to define missions for signal search and tasks for process control.

  • Wideband signal scenario

  • List of classified signals

  • List of actual mission tasks

  • List of stored missions

Based on this set of rules go2MONITOR will automatically detect signals, classify, demodulate and decode.

  • Graphical result display

  • Decoded text

  • Signal IF recording

  • Result selection

  • Signal metadata

  • Emitter position and bearing

The results are stored in a database for further evaluation. An advanced ResultViewer shows a tabular or graphical representation of the stored data.
