release news – Go2signals 22.1

INCREASE INPUT BANDWIDTH
FROM 1 TO 5 MHZ AS STANDARD

With this new release, go2MONITOR offers now a wider input bandwidth of 5 MHz (VUHF, 1 MHz HF) for wideband detection, classification and recording as standard configuration. Decoding channels band-
width has also been increased from 1.5 to 4 MHz, which e.g. enables decoding of the new ADS-B decoder even in the basic version without additional costs.

New AMT task type:
Continuous Fixed-Frequency Monitoring

Automatic monitoring and tasking (option AMT) is one of the performance features of go2MONITOR. The main use case is to filter with wideband classifier parameters for SOIs and decode them fully automatically. If the frequencies of SOIs are known, this new task type can set up a fixed decoding channel to permanently monitor this frequency for signal activity.

New Signal Activity
Triggered Recording

Each decoder channel in go2MONITOR has its own IF recording function. New in 22.1 is the possibility to set a SNR threshold to record only active signal parts and remove the pauses automatically. Additional
parameters like leadtime, duration, etc. complete the new feature.

This feature is also part of the configuration of “Continuous Fixed-Frequency Monitoring” tasks (with option AMT).

Decoder and Demodulator Enhancements

As with every release, we updated our demodulators and decoders to stay current with the changing
signal world and provide a better experience.
This time we particularly highlight new decoders for ADS-B or HF fax modes and new decryption
features like implemented in TETRA or DMR.

pyDDL News

A special feature of go2MONITOR enables the customer to develop their own decoders and integrate them into their systems. This release is the next step in expanding the decoder development language from DDL to pyDDL. The long list of new features and converted decoders underlines this progress.

Additional pyDDL features

• New helper functions for splitting a BitBuffer into smaller chunks
• Added a predefi ned hamming code generator matrix for BlockDecoder
• search_pattern: defining a pattern mask is no longer always neccessary
• generate_lfsr_sequence: allow up to 64 bit (was 63 bit)
• Faster hamming weight calculation (pop count) of long bitbuffers
•  Added alphabet CCIR 476 (SITOR)
• Added alphabet ITA3

Classifier Enhancements

Modulation and modem classifiers process the entire wideband input band to obtain detailed information about all signals received and filter for Signals of Interest (SOI). The entire input band is split into individual signals, classified, and signal changes are tracked. The most important new functions
are listed here:

• New modulation classifier for OQPSK
• New modem classifier ALE-4G
• New modem classifier DAB
• New modem classifier DVB-T
• Added new DMR-Cont. variant

Additional Receiver Support

With this release, we have enhanced the support for popular Rohde & Schwarz communications receivers.

• R&S ESMD receiver: Added receiver control and IF-Panorama / Panorama-Scan support

• R&S EB500 receiver: Added IF-Panorama / Panorama-Scan support

• Added support for Jumbo-Frames to increases maximum bandwidth for R&S receivers

• Update driver version for USRP receiver to solve some communication problems

Noteworthy Changes

• Updated frequency range for SAT-X to 7.2-10.7 GHz
• New corporate design for icons, splashscreen etc.
• Decoders with additional files (for example alphabets) can now be used with go2MONITOR
• Improved system shutdown process to allow all result files to be closed and all actions to be finished properly
• The length of NB-recording files stored by AMT tasks changed from 30 s to 5 minutes to match the length of produced audio files.
• Changed triggering strategy in AMT: If begin of triggering emission cannot be reached by using delay buffer, the action will start with the current time and not with the maximal delay time
• Improved detection if frequency is already processed for AMT Live Processing task, to prevent duplicate processing of the same emission
• Parts of AMT Task Wizard redesigned
• Changing time from-to in ResultViewer for recording results is not possible anymore, to make sure that metadata in the database fits underlying recording files and their meta-information
• Configuration with longer maximal delay time (license option) in a channel allow entering delay value manually instead of only choosing from a drop-down
• If trigger based on detection in overview spectrum is used in an AMT-Live task, the option “Use modem list from trigger emission” will be turned off and disabled
• In Viewer GUI configuration, File or Stream Playback address for narrowband channels will be determined automatically, without need to set “FilePlaybackIPAddress” value in the configuration
• Various improvements in frequency management: Column group will be automatically enlarged during editing, new frequencies will remain visible after adding, speed up frequencies import with duplicated entries
