go2MONITOR Specification
- System
- Classifier
- Demodulators
- Decoders
- Supported Receivers
- Hopper Detection
- Computer Recommendations
General
Classifier/Recognition:
- The minimum signal length for the wideband modulation classifier is 100 ms.
- Using the decoder (Recognition & Decoding) , the software is able to detect and process signals with a signal length of at least 1 ms.
Decoders and Demodulators:
- 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 decoderlist
- 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 DDL compiler)
Receivers:
- The list can be extended on customer requests.
- It is possible to connect multiple wide band an narrow band receivers to the software.

Decoders
- You can add new decoders or modify existing source code (SRC).
- MIL decoders require an end user certificate for delivery outside Germany
- PMR decoders require an end user certificate for delivery outside EU
- SAT decoders are included in the PMR package and require an end user certificate for delivery outside EU
Soure Codes (SRC)
- Source Code provided.
go2DECODE is required to modify the protocol or to add additional output to the decoder (new alphabets, new META data handling etc.)
Decoder Package (PKG)
- STD, included in basic products
- MIL, requires EUC outside Germany
- PMR, requires EUC outside EU
- SAT, part of PMR Package
Legacy Decoders
- Old, obsolete or outdated decoders are also included, as it cannot be guaranteed that such signals will not be reactivated. The information can only be given with great uncertainty.
- November 2109 we again found signals marked before as legacy... sorry. But that's why we're also doing the monitoring to check the situation

Hopper Detection
| Parameter | Description |
|---|---|
| Search bandwidth | MF/HF: 2.4 MHz (no scan) VHF/UHF: 20 MHz (no scan) |
| Minimum signal duration | ≥ 2000 ms duration for frequency hopper; min. 100 hops |
| Hop rate | 5 to 50 hops/s for MF/HF or 100 to 1000 hops/s for V/UHF |
| Hop properties | Hops belonging to one FHSS emission are expected to be similar in spectral shape. This applies for most digital - e.g. PSK based - modulations. Individual hops should contain several symbols. |
| Signal Input | Signal input from PLATH SIR 5110 (using IP UDP Protocol) Signal input from PLATH SIR 2115 (using IP UDP Protocol) Signal input from IZT R3xxx Other receivers on request |
| Recommended hardware | Standard HP DL360/380 Gen10 Server (alternatively Blade) with 2 x Intel Xeon-Gold (6152) 128GB DDR4-2666 RAM 2 x 300GB SAS 12G 15K 1 or 10 GbE LAN |
| Operating System | Windows Server 2016/2019, 64 bit; CentOS 7.x (7.5 or higher; 7.5 is recommended) 64 bit Linux. English or German. |
| Parameters for each detected Frequency Hopper (FH): | Description |
|---|---|
| Hopper ID | Unique identifier of the hopper |
| Frequency From | Lower frequency limit of the FH |
| Frequency To | Upper frequency limit of the FH |
| Start time | Start time of the FH (first time of detection by the HOPD) |
| End time | End time of the FH (last time of detection by the HOPD) |
| Hop Rate | Estimated hop rate in hops/second |
| Mean dwell time | Mean value of measured hop dwell times |
| Standard deviation dwell time | Standard deviation of measured hop dwell time |
| Mean inter-hop pause time | Mean value of measured inter-hop pause time |
| Standard deviation inter-hop pause time | Standard deviation of measured inter-hop pause time |
| Mean hop bandwidth | Mean value bandwidth of all hops assigned to this hopper |
| Number of channels | The number of frequency channels used by the hopper |
| SNR | SNR estimation based on all hops seen for this FH emission |
| Parameters for each Frequency Hop: | Description |
|---|---|
| Hopper ID | Unique identifier of the hopper |
| Frequency From | Lower frequency limit of the hop |
| Frequency To | Upper frequency limit of the hop |
| Start time | Start time of the hop |
| End time | End time of the hop |
| SNR | SNR estimation |
| FHSS ID | ID of FH this hop belongs to (if any) |
