Detectors

Receivers

  • SignalHound BB60D support
  • VITA49:
    • Simplified templates for VITA49 receivers
    • Automatic parsing of TSI and TSF types from the input stream
    • Acceleration of the interface to extend the maximum possible bandwidth
  • R&S:
    • Use of the full supported input bandwidth of go2signals software with receivers by using the effective bandwidth of the receiver for license checking instead of the sampling rate
    • For some R&S receivers, multiple semicolon-separated user-defined SCPI commands can now be specified for initialization
  • IZT: UdpDestMonitoring function is now switched off by default.

go2MONITOR

GUI

  • The "Task Overview" window replaces both the "Mission Statistics" and "Mission Channels" windows and provides a more detailed view of task parameters and results in automatic mode, as well as advanced display filter options.
  • New window called "Task Channel Monitoring". It offers the possibility to watch selected channels during automatic processing, see first results and listen to the signal live
  • New wideband signal input type: "Wideband Recording". Wideband recording can be used for all manual and automatic operations. This includes several changes in the WB Inputs GUI, the ResultViewer and the Automatic Wideband Monitoring.
  • The new Context Match... feature provides automatic search for user-defined text patterns in decoder results, including result labeling, highlighting, and alerting.
  • The management of keyboard shortcuts has been improved to include the entire GUI instead of only the ResultViewer. In addition, some standard keyboard shortcuts have been changed to resolve conflicts with common keyboard shortcuts such as Return, Ctrl+C, etc.
  • The combobox component for multiple selections has been improved and now offers filter functions and better performance. This component is now used for selecting tasks, missions, antennas etc. in the GUI
  • AMT: The new "Result comment" field Tasking can be used to specify a user-defined text that will be added to the comment field of all results generated by this task
  • Custom Python-based functions can now be integrated into the narrowband channel GUI and displayed in its toolbar
  • The database engine has been updated from PostgreSQL v10.6 to v14.5
  • Bulk file processing: The name of the source file is now displayed in the source field of all of all results
  • AMT wizard has been modified to include new features functions and a improved layout
  • TCP port usage optimized to use fewer ports in configurations with "Operator GUI"
  • The signal input combo box in the narrowband channel now includes the SignalServer ID
  • Improved system start/stop sequence to reduce wait times
  • Improved mission/task import function to import content matching lists and import antennas if they are available in the target system
  • Improved mission/task import feature to allow import of data from older versions if all required information is available
  • Source IP address/port is now available in the context menu of the spectrogram context menu visible in the narrowband channel view
  • Performance improvements when filtering frequency lists with user columns
  • The performance of the decoder post-processing function has been improved
  • Faster frequency stepping in the narrowband channel are now possible

Classifier

  • PSK classifier extended for symbol rates up to 50 MBd/s
  • Tetrapol and Tetra Uplink, improved detection of
  • Link 11, improved  detection to avoid false positive classifications
  • FLEX, new modem classifier

go2DECODE
