ChipGraft's Navisock is the first receiver to integrate all global GPS systems on one chip.

1. Radio Wnet's 'Limes Inferior' program on the digital world hosts an interview with Paweł Narczyk, president and co-founder of ChipCraft, a Warsaw Polytechnic spin-off. 2. Host Szymon Augustyniak presents ChipCraft as one of six rising European stars in the GNSS (satellite navigation) semiconductor sector. 3. The episode's central argument is that Poland has the engineering talent to build a global semiconductor industry but lacks the state policy mechanisms — primarily domestic procurement — to sustain it. 4. NaviSOC, ChipCraft's flagship product, is the world's first single-chip GNSS receiver to simultaneously integrate all four global satellite systems: GPS (USA), Galileo (EU), BeiDou (China), and GLONASS (Russia) on one silicon substrate. 5. The chip currently achieves meter-level accuracy and is being developed toward 20-30 centimeter accuracy using Galileo's High Accuracy Service — a correction signal broadcast from satellites that requires no additional communication infrastructure. 6. Narczyk identifies lane-level automotive navigation and precision agriculture as the two primary applications for 20-30 centimeter accuracy: lane detection for cars and reduced fertilizer waste in precision farming. 7. In precision agriculture, centimeter-level GPS accuracy reduces the overlap tab between field passes, cutting fertilizer and pesticide use — and enables autonomous small agricultural machines as an alternative to large human-operated equipment. 8. ChipCraft has an active project with the European Space Agency to add advanced anti-jamming and anti-spoofing functions to the NaviSOC chip. 9. Narczyk explains jamming as signal overpowering (a high-power broadcast that drowns out satellite signals) and spoofing as injection of false position data — giving the example that spoofing a drone's altitude reading can force it to crash-land. 10. The ESA-funded anti-spoofing system includes automatic fallback to inertial navigation using accelerometers and gyroscopes when satellite signal is jammed, continuously checking for signal recovery to switch back. 11. Narczyk explains the fabless production model: ChipCraft designs chips but sends them to external semiconductor foundries (fabs) for production, because building a modern fab costs 20-30 billion dollars and is beyond the reach of any single company. 12. The NaviSOC chip measures 6x7 mm and contains 80 million transistors, of which 90% are digital logic and 10% analog; Narczyk explains that the analog portion takes more design time than the digital despite being the smaller part. 13. Designing an integrated circuit at ChipCraft involves 2-3 years of development work, followed by 5-6 months of prototype production, with an iterative cycle of simulation, layout, extraction, and physical measurement to achieve simulation-physical convergence. 14. ChipCraft finances itself through a combination of design services for third parties (including a touch-screen controller now used in millions of electric cars and Samsung refrigerators) and 70-80% government or EU B+R research grants. 15. Narczyk describes increasing difficulty accessing R&D funding, noting applications have become more complex and politically influenced, and calls for simpler policy tools — specifically, mandatory domestic military procurement of semiconductor components. 16. He cites the example of guided/programmable ammunition purchased abroad by Poland's military as a missed opportunity to develop domestic semiconductor capability for defense. 17. Narczyk argues that a semiconductor production line in Poland — specifically the CEZAMAT pilot line at Warsaw Polytechnic — is technically feasible but requires a political decision to fund industrial-scale machinery. 18. The interview is a single extended conversation between the host and one expert guest, technically dense but accessible, with the host framing context and Narczyk providing detail. 19. Polish engineers and technology policy listeners interested in semiconductor sovereignty, GNSS technology, and the gap between Polish technical talent and industrial policy will find detailed insider perspective. 20. Listeners who do not follow semiconductor manufacturing, Polish tech policy, or satellite navigation technology will find the episode's technical depth difficult without background.
