go2MONITOR ENHANCEMENTS

NEW FUNCTION: COLLABORATION FEATURE

Sharing tasks, resources, results, etc., multiple workstations can perform radio spectrum monitoring in parallel. Operators can now exchange messages, share data and results of interest, and send task requests to each other in real time. These new features improve team collaboration and help streamline workflows for faster, more effective operations.

New Collaboration features inside go2MONITOR for sending and receiving request

With the new feature, sharing of a signal or frequency is now a simple task. The new Client View provides a detailed overview of all clients currently connected to the go2MONITOR system, including information on their production channels usage. 
For example, you can ask another connected operator to have a look on the same frequency on which you found an important signal. He will receive a message in his collaboration window and can then decide whether to set up a new local channel for the signal or simply look into the same channel you are currently using.

A second workplace receives the request and opens his own channel on that frequency

You can also send requests while reviewing results in ResultViewer. For example, send a request to a colleague to view a specific result stored in the database, or send him a special filter for the database you are currently using to review results.

Collaboration during result reviewing in ResultViewer

ENHANCEMENT: NEW RESULTVIEWER AUDIO PLAYER

The ResultViewer has been upgraded with a powerful new audio player that automatically skips silence, allows selection playback, supports loop and variable speed controls, and includes a playback squelch function. The player can merge and play audio from multiple results, enabling operators to listen to communications originating from different results simultaneously.

Select two frequencies in duplex connection to easily add and listen audio from both channels

UPDATED: OVERVIEW MAP DISPLAY

The overview map display in ResultViewer has been improved to interact not only with the table view but also with Time/Frequency and Timeline views. Only currently selected results are displayed, this offers a more focused and precise result visualization.

The new Overview Map Display works now together with all three result views

REDESIGNED: POSITION RESULTS

Adding many new features, the Position View in ResultViewer has undergone a complete redesign. Operators can now add and edit bearings and positions, assign bearings to positions, and automatically compute position fixes from bearings. The map display now shows bearing tolerances, position tracks, and more.
 

Redesigned Position View

The main functions of the view:

  • Display bearings and positions in a geographic overview, including tracking of positions
  • Interactive editing and maintenance of bearing and position data, including manual creation, correction, assignment, and deletion of individual entries
  • Support for localization and tracking of radio emitters based on a included position determination algorithm and position tracking

ENHANCEMENT: ADDITIONAL WIDEBAND INPUT FEATURES

The wideband input bandwidth in go2MONITOR is defined by the receiver used or the bandwidth of a replayed recording. It may also be wider than the wideband classification bandwidth. If this is the case, the classifiable range is marked in the spectrogram. Two new features give you now the possibility to flexible use this range and enlarge it over the complete input.
 
MOVABLE WIDEBAND CLASSIFICATION RANGE
The wideband classification frequency range is no longer fixed to the input center; it can now be freely and interactively moved, giving operators more flexibility when working with different frequency ranges.
 

Example: Reduce and move classifyer bandwidth for a selected input

MEMORY-STEP WITH TWO-STAGE ALGORITHM
Memory-Step (part of automatic monitoring AMT) now uses a two-stage algorithm that takes the wideband classification bandwidth into account. The process first steps across the input by moving the wideband classification range, followed by tuning the receiver for optimal performance.
 

Two-stage algorithm optimizes the memory step function

ENHANCEMENT: NEW AUTOMATIC MONITORING FEATURES (AMT)

AUDIO DEMODULATION AND RECORDING

AMT tasks now include a new “Audio Demodulation and Recording” action to automate audio processing without consuming production channels. This improves resource management and efficiency because no decoder is used.

New AMT Audio Features

WIDEBAND CLASSIFICATION TRIGGERS

AMT tasks can now be triggered by modem detections reported by the wideband classifier. This adds another layer of automation and precision to task execution.

New Trigger Feature using modem classification

CARRIER TRIGGER
A new “Carrier” modulation type has been added as a valid trigger condition in AMT tasks. This gives you the option, for example, to trigger emissions that use a carrier in idle mode.
 

Trigger by carrier detection

FIXED MODEM LIST OPTION
AMT tasks can now use a predefined, parameterized modem list directly – without validating it against the modems detected by the classification process. Ideal if the typical modems for a frequency are already known.
 

New option fixes the used modem list to customer specification

SIGNAL ANALYZER ENHANCEMENTS

RENAMING AND SOFTWARE MAINTENANCE

We took this release as opportunity to carry out software maintenance and make detailed improvements to the Signal Analyzer. Firstly, the name was changed from ‚Signal Analyzer‘ to ‚go2signal-analyzer‘ to emphasize its connection to the go2signals universe more clearly.
For example, improvements have been made to support SignalHound IQ files with float samples and splited data files, as well as to the gain adjustment in Midas Blue files. The application now saves additional spectrogram settings in its project files, and the Signal Information Database search features have been enhanced.

GO2SIGNALS ANALYSIS SUITE

INTRODUCING THE NEW GO2SIGNALS ANALYSIS SUITE

The new go2signals Analysis Suite is now available, providing a comprehensive and integrated toolbox for advanced signal analysis, decoder development, testing, and training. While the go2signals-analyzer is already well established among users, an new brochure now presents the complete Suite and its components.
The go2signals Analysis Suite brings together all essential tools required to analyze unknown signals, create or adapt decoders, generate realistic training scenarios, and extract ARC4 cipher keys for DMR systems.
This toolbox forms a flexible, military-off-the-shelf solution that enables operators and analysts to respond quickly and effectively to new, changed, or challenging signals. The Analysis Suite ensures seamless workflows – from the very first detection of unknown signals all the way to deployment in go2MONITOR.
Discover the complete capabilities in our new product brochure and experience the next level of operational readiness and analytical performance.
