go2signals go2MONITOR

Request Info

With go2MONITOR you have a software tool that covers the entire workflow in the area of radio signal monitoring and COMINT. The software is modular, configurable and scalable, and can be customized to meet your exact needs.
Manual processing of intercepted communications is too expensive, too slow, insecure and incomplete. In this situation, an automated, flexible and extensible approach must be used with reasonable effort and at an affordable cost.

Key Facts

  • HF, VHF and SHF all in one package
  • Fully automatic signal processing of data and voice signals on multiple channels
  • Simultaneous automatic AND manual monitoring with parallel classification of signals
  • COTS hardware (computers, receivers)
  • Multiple coherent wideband inputs
  • Input bandwidth up to 200 MHz MHz, depending on receiver, driver and computer performance
  • Panorama overview (depends on receiver)
  • Large and expandable decoder library
  • Stay up-to-date with two updates per year
  • Windows or LINUX

Technical Data

Comments:
  • Using the classifier (Recognition & Decoding) , the software is able to detect and process signals with a signal length of at least 1 ms.
  • MIL and PMR decoders may need an End-User-Certificate (depends on the country of the user)
  • One decoder = one line (to shorten the list). For the full list, download the actual decoder list
  • Slow multi tone modems are recommended to operate with fixed nominal frequency
  • Decoder source code is only part of go2DECODE delivery (as go2MONITOR has no pyDDL compiler)
  • The receiver list can be extended at the request of the customer or by the-user/integrator (receiver plug-in tool).
  • It is possible to connect multiple wide band and narrow band receivers to the software.
  • Yellow = New or changed
