Development
We are ready to help you with the development of software and hardware for your applications, we focus on the development of software defined radio for satellite communication. We develop electronics.
What Services We Offer
We supply most of the activities in the development of modern radio transceivers, especially for the satellite link establishment. This includes SW design targeted to Microcontrollers, DSPs or FPGAs, and HW electronics in embedded systems even RF design in GHz bands. If you do not fit into any specific group of our expertise or you just need to consult your application do not hesitate to contact us.
Signal Processing Development
Development and customization of signal processing algorithms for software defined transceivers.
We start development with scripting and analysis, and then implement, optimize and verify its behaviour on your target whether it is based on FPGA, DSP, small microcontroller or PC.
Embedded Software Development
Coding from applications for small microcontrollers through FreeRTOS implementation up to uBoot and Linux customization for your target boards.
We mostly write drivers for custom board designs or high level scripts in Python for user applications or Web interfaces.
Digital and RF Electronics Development
Development and design of high-speed digital and RF communication boards.
We focus mainly on miniaturized FPGA and Microcontroller board designs serving for satellite communication with SDR implementation aimed up to GHz frequency bands.
Recent Work
Signal Processing for JuRa
2018-2024
Together with EmTroniX, IPAG, TUD, Astronika, GomSpace, ESA and others we created a Juventas Radar (JuRa) for Juventas cubesat intended to explore the Dimorphos, moon of the Didymos asteroid. Our controbution is essential, We designed the signal processing core on FPGA to perform radar operations. Now Juventas togehter with his mother spacecraft HERA is on its long journey through space.
Snow Fox SDR
2021-2025
We are developing a custom Software Defined Radio targeted for satellite data downlink in wide frequency range up to low Ku-band. The design is complex, including HW and SW design and prototype manufacturing. We reached the second prototyping stage which is now under thorough testing. Read the product page to get more information about the initial version.
X-band Transceiver Driver
2023-2024
With collaboration with Czech Space Research Centre on the development of nanosatellite we developed the driver for transceiver onboard of the cubesat used for high-speed data downlink in X-band. The driver is an application in Python running under Linux environment. The software is ready now and we are awaiting the launch.
Sampling Rate Conversion
2025
From many projects we learned that customers are not always aware of efficient implementation of the sampling rate conversion and as a result are wasting of resources and their products cost more than needed. We provide developer-understandable article to get the key points for efficient implementations of decimators, interpolators and fractional resamplers. If you learn that this is still beyond your capailities, we created user-friendly IP cores for FPGAs with unprecedented implementation efficiency.
