Summary
🤩
Rockstar🎓
Top SchoolJavier Arribas is a telecoms researcher-turned-entrepreneur with 14 years' experience in GNSS signal processing, RF front-ends and real-time embedded systems, now co-founding and leading WaveMasters to tackle GNSS anti-jamming and anti-spoofing with CRPA and SDR architectures. He holds a PhD in Telecommunications and has deep hands-on expertise from implementing core components of the widely used GNSS-SDR open-source receiver—adding 4-bit complex sample support, timestamping, and Galileo E6 pseudorange features. As a long-time senior researcher at CTTC and former GSOC mentor, he blends academic rigor with practical system design and FPGA experience to deliver production-capable positioning solutions. Based in the Greater Barcelona area, Javier’s background uniquely spans founding engineering teams, applied research, and open-source stewardship—bringing both strategic leadership and low-level signal-processing chops to resilient GNSS products.
