go2signals
go2signals is PROCITEC's modular software package for radio signal monitoring and analysis. It automatically detects, classifies, demodulates and decodes HF and V/UHF communications, scaling from a manpack to a multi-user COMINT system. More than 350 decoders are included.
What is go2signals?
go2signals is the software package that PROCITEC GmbH, a specialist based in Pforzheim, Germany, sells for the monitoring and analysis of wireless communication signals. It spans SLF to SHF and is tuned for the HF and V/UHF ranges, and it is sold to organisations that regulate, police or exploit the radio spectrum: regulatory authorities, police forces and border guards, civil agencies, intelligence services and armed forces working in electronic warfare, CESM and COMINT.
The package is modular rather than monolithic. Its named components include go2MONITOR for automatic search and multichannel production, go2DECODE for demodulation and decoder development, and go2ANALYSE for bit stream work, with Signal Analyzer, the ResultViewer and the SOMO signal generator alongside them. All of them carry the same release number, currently 26.2, and PROCITEC ships two versions a year.
In automatic mode the software runs missions and tasks: it detects emissions across a band, classifies their modulation, demodulates and decodes them, then files results, metadata and recordings in an internal database that the ResultViewer exposes for filtering, replay, tagging and export. The decoder library covers military, PMR, satellite, analogue speech and Morse traffic, and more than 350 modem types are supported. In manual mode an analyst can measure the parameters of an unidentified signal, work through its bit stream with search, measurement and logic functions, and then build a decoder for it in the pyDDL description language.
The same functions are sold to system integrators as an OEM core, with or without the graphical interface, driven through an open TCP control interface with an ICD and a documented API. Hardware is free choice COTS: receivers connect through existing drivers or open interfaces such as ExtIO and VITA 49, and deployments range from a highly mobile manpack to a semi-stationary or multi-user installation on land, at sea or in the air.
One caveat matters for readers of an AI directory: PROCITEC does not market go2signals as an artificial intelligence product. Across the pages collected, the word appears exactly once, in a sentence about keeping up with technology. What the software automates is signal recognition and classification.
What it does
- Detect and separate signals from noise across wide bands, including frequency-hopping emissions
- Classify modulation types automatically, in wideband or narrowband, continuously or on a snapshot
- Demodulate and decode with 35 demodulators, over 200 decoders and more than 350 modem types
- Process several hundred channels in parallel, and faster than real time when working offline
- Record wideband I/Q, narrowband channels and demodulated or decoded audio without loss
- Analyse unknown signals by hand, measuring modulation type, symbol rate and shift, then inspecting bit streams
- Build custom demodulators and decoders in the pyDDL language with an integrated debugger
When to use go2signals / When not to
A quick filter to help you decide if go2signals is the right fit.
When to use go2signals
- SIGINT and COMINT analysts who intercept, exploit and report on communication signals of interest
- Spectrum monitoring operators at regulatory authorities who police and enforce frequency allocations
- Police forces and border guards that need to identify and record radio traffic during investigations
- Military electronic warfare, CESM and COMINT units deploying tactical or semi-stationary collection systems
- System integrators looking for an OEM signal-processing core with open, documented interfaces
When not to use go2signals
- Individuals and small businesses: there is no public price, no self-service purchase and no free plan
- Anyone expecting a browser-based SaaS: the software is installed on Windows or Linux workstations
- Mobile-first users: no iOS or Android application exists for this product
- Teams without radio receiving hardware, since receivers and I/Q sources must be supplied separately
- Buyers looking for generative or office AI: go2signals processes radio waveforms, not text, images or music
How to use go2signals
A typical end-to-end flow, from setup to results.
- Contact PROCITEC through the enquiry form or the sales address: there is no online purchase and no self-service sign-up
- Ask for a trial licence or demonstration version, which the vendor issues after a conversation with its experts
- Define the scope with PROCITEC, which interviews users, operators and purchasers before proposing a configuration
- Choose the COTS hardware and the receivers, then connect them through existing drivers or open interfaces such as ExtIO and VITA 49
- Install the software on Windows or Linux, setting the interface language in the prolang.cfg file if German or English is preferred
- Declare the receivers in the Receiver Configuration Tool, checking IP addresses, ports and jumbo frames where the receiver requires them
- Create an active mission, then add tasks with triggers, start and stop criteria, priorities and scheduling
- Let the automatic chain run, or switch to manual processing for a single unknown signal
- Work the output in the ResultViewer: filter, replay, tag, navigate the offline spectrogram and export what matters
- Extend the system over time by writing decoders in pyDDL or by subscribing to an update and support package
Pros & Cons
Pros
- A decoder library that few competitors match, kept current by two releases a year
- Genuine modularity: the same concept of operation runs from a manpack to a multi-user system, with data moving between them
- Open, documented interfaces (TCP control, ICD, API) that let the software sit inside a third-party system as its processing core
- Independence from the vendor: customers write their own decoders and keep that expertise rather than handing it over
- Free choice of COTS hardware, with no proprietary DSP unit to buy
- Quality management certified to ISO 9001:2015 by TÜV SÜD under certificate 12 100 34289 TMS, valid until 13 July 2029
- An established publisher: PROCITEC has been on the commercial register since 1999 and employs around sixty people
Cons
- No public price at all: neither a licence figure, nor a tier, nor a currency appears anywhere on the site
- No terms and conditions are published, so nothing contractual governs licensing, liability or permitted use
- No self-service trial: the trial licence is granted after contacting the vendor, and the site never says it is free
- No API documentation is available online; the interface control document ships with the product
- The interface exists in German and English only
- There is no mobile application, and the software must be installed on Windows or Linux with separate receiving hardware
- The privacy statement covers the marketing website alone, leaving nothing published about data handling on the product side
Pricing & Plans
There is no free plan and no published price. PROCITEC does not disclose the licence fee for go2signals: every commercial path on the site leads to an enquiry form, so the entry point can only be obtained by quotation. The only figures published are for the optional service packages, and they are expressed as a percentage of the licence price rather than as an amount: fifteen per cent per year for the standard update package, twenty per cent per year when priority support is added, and ten per cent for each missed release when a one-time update is purchased. A trial licence is available on request, but the site does not state whether it is free of charge.

Data, GDPR & hosting
A consolidated view of how go2signals handles your data.
GDPR overview
PROCITEC GmbH is a German company, so the GDPR applies directly. Its privacy statement names the controller (PROCITEC GmbH, Rastatter Straße 41, Pforzheim) under Article 4(7), designates an external data protection officer by name (PROLIANCE GmbH, Leopoldstraße 21, Munich), lists the data subject rights of Articles 15 to 21 plus the right to complain to a supervisory authority, and cites its legal bases explicitly, including Article 6(1)(a), Article 6(1)(f) and Section 25(1) TTDSG. The scope is narrow, however: the document states that it informs about data collected during use of the website, and says nothing about the go2signals software or about data handled by customers. No data processing agreement is published or offered, and the site never claims GDPR compliance for the product itself.
Who owns the data?
PROCITEC publishes no terms and conditions at all: eight likely paths were probed and every one returns a genuine 404, and the 52-URL sitemap contains none. The only legal documents on the site are the imprint and the privacy statement, and the latter expressly covers the website alone, naming PROCITEC GmbH as controller under Article 4(7) GDPR. Because go2signals is installed on the customer's own Windows or Linux machines, the results database, the I/Q recordings and the decoders live on customer infrastructure and no published clause claims any right over them. The vendor does state that decoder know-how stays with the customer, without being shared with third parties first.
Reuse rights
No contractual document on the site restricts what a customer may do with the material the software produces, simply because no terms and conditions are published. In practice the product is built around reuse: the ResultViewer lets operators filter, replay, tag, structure, edit, combine and export results, recordings can be kept losslessly for documentation or later processing, and version 26.2 adds binary .pcap and XML outputs for several decoders. Decoders and classifiers written by the customer can be exported to other go2signals installations, and PROCITEC states that this expertise is not transferred to third parties. Readers should note that this permissiveness reflects an absence of published rules rather than an explicit licence grant.
Data retention & training
Hosting summary
go2signals is installed on the customer's own Windows or Linux machines, so PROCITEC hosts no operational data: the results database, the I/Q recordings and the audio files are written locally, and the vendor's own FAQ gives the directory paths on both operating systems. No hosting country or region is declared anywhere for the product, which is consistent with an on-premise deployment. Two things should not be confused with it. The marketing website is served from Germany, on an IP address belonging to Hetzner Online in Nuremberg, with no content delivery network in front of it; that is the site, not the product. And the European Union processing location mentioned in the privacy statement, together with the transfers to the United States listed there, applies to the third-party analytics and marketing services running on that website, not to go2signals.
Things to keep in mind
Risks and trade-offs to weigh before adopting go2signals.
- This is a dual-use communications surveillance capability: the site itself names intelligence services, police and armed forces as users, and lawful deployment depends entirely on the national legal basis behind it
- No terms and conditions are published, so nothing contractual defines licensing, liability or permitted use of the software
- No price is public and the service packages add fifteen to twenty per cent of the licence fee every year, which makes the total cost impossible to estimate without a sales conversation
- The privacy statement covers the marketing website only, so no published commitment exists about the data the product handles
- Automatic classification invites over-confidence: PROCITEC itself provides a manual mode and a decoder development environment precisely because unknown signals defeat the automatic chain
- The system depends on third-party receiving hardware and on trained operators; the automation reduces workload but does not replace analysis
- Ownership runs through a holding company: PROCITEC GmbH is held by PLATH Corporation GmbH within the family-owned PLATH group, and the ultimate beneficial owner is not public because the German transparency register is closed
Setup & Integrations
Technical difficulty
High. The software is installed locally on Windows or Linux, with configuration files edited by hand for the interface language and the analysis tools. Receivers must be declared in a dedicated configuration tool, where the vendor's FAQ discusses IP addresses, ports and jumbo frames for certain hardware. Operators then have to understand missions, tasks and triggers before a single result appears, and deeper customisation calls for Python, SQL and the pyDDL decoder language. PROCITEC offers basic and software training courses as well as help with solution design and integration, which the product realistically requires.

Should you pick go2signals?
go2signals is a specialist tool sold to organisations rather than to individuals, and it is unusually easy to judge on its technical merits. The decoder library, the range from wideband search to bit stream analysis, the ability to write your own decoders in pyDDL and the open control interface are all documented in detail on PROCITEC's own pages, and they describe a mature product: the company has been on the register since 1999, the go2signals line dates from 2015, version 26.2 shipped with integrated direction finding, and two releases a year are contracted through the service packages.
What is not documented is the commercial side. No licence price, no tier and no currency appear anywhere. No terms and conditions exist at all, which is unusual for a software vendor of this size and leaves licensing, liability and permitted use unstated in public. The trial licence has to be requested, and nothing says it is free. Buyers should expect a sales conversation before any figure, and should budget the service package on top, at fifteen to twenty per cent of the licence price every year.
Two further points deserve attention. The privacy statement covers the marketing website only, so nothing is published about how the product itself handles data, although the software runs on the customer's own machines. And PROCITEC does not present go2signals as an artificial intelligence product: what it automates is signal recognition and classification, which is pattern recognition applied to radio. Readers browsing an AI directory should weigh that framing themselves. As a dual-use monitoring capability aimed at intelligence services, police and armed forces, it also sits in a domain where the legal basis for use matters as much as the software.
