Training
Get up to speed with full-day CCSDS/PUS training. We’ll also talk about your specific communication architecture and challenges.
- CCSDS and ECSS PUS protocols
- Space data architectures
- Gaps in the standards
- Pitfalls of Space communication
- PUSopen® APIs and dynamics
- Tailoring of protocols
- Integration with your platform
- Achieving the “flight quality”
Tailoring and Integration
Adapt the protocols on the Byte level. Almost every integration of CCSDS and PUS needs a few tweaks to match the other end of the communication. Configure PUS protocols by simple configuration.
- Adapt protocols on the byte level
- 33 points CCSDS and PUS tailoring checklist
- Scalable for any RAM size and OS-independent
- Toolchain integration support
Custom Extensions

Your FAQ
Just send us an email. Atop of being professional, we're quite friendly.
How is PUSopen® distributed?
You get a ZIP package: full source code, library (.a, .so., .dll), documentation, tools, build scripts, and XML configuration.
How can we purchase PUSopen®?
Download the PUSopen® Evaluation version, and we’ll email you back. We’ll sign the NDA, discuss your requirements and license, and deliver the full PUSopen® package. You can have it in a few days.
Which support can we get?
You’ll get support throughout evaluation, build integration and tailoring, test campaigns, pre-flight, and operations. Our support is based on experience from real missions. We’ll be as involved as you find useful.
Which use cases are supported?
Our customers used PUSopen® to prototype their Space applications, to build Ground Stations, in test equipment (EGSE), and, of course, onboard their custom payloads.
What are custom PUS services?
Custom PUS services have service ID > 127 (according to the ECSS standard). For example, specific operations of your custom payload, custom data transfer, etc. – anything not covered by the standard ECSS PUS services.
Which language bindings are available?
PUSopen® is written in C. We provide wrappers for Python, C++, and C#.
Is source code provided?
Yes. PUSopen® standard license includes full PUSopen® source code. It allows you to re-build PUSopen® for your specific OS and CPU.
Can we order only training?
Yes. Call us, and we’ll organize a CCSDS / ECSS PUS training session for your team. We can customize it for your mission and make it a practical workshop (data architecture, practical implementation of PUS, implications).
Which build systems are supported?
Cmake, plain Makefile, GitLab – all commonly used build systems and tools. We’ll set up a Git repository for you so you can make your custom extensions and receive PUSopen® updates.
Which platform and OS are supported?
PUSopen® is OS-independent. Our customers used it on ARM, Intel, Xilinx Zynq, RISC-V, MSP-430, Windows (prototyping), Linux, and Free RTOS.
How much does it cost?
It depends on your customized package. Let’s sign an NDA so that we can talk more freely. We promise not to break your budget.
Where can we find PUSopen® EULA?
Email us, and we’ll send any information you need to decide – including EULA. Looking forward to talking to you.
