SDR Driver for Precise Timing Applications

This paper describes the development of software drivers that enable precise timing applications with the low-cost HackRF One software-defined radio (SDR). The original firmware was extended with timing functions for synchronized sampling, time-scale control, and clock-frequency adjustment. An initial implementation based on a Python wrapper was later redesigned as a SoapySDR-compatible driver. Using an AI-assisted development workflow, the new driver was generated from the existing HackRF One and SoapySDR codebases and became operational after only limited debugging. The approach reduced development effort by more than an order of magnitude while improving software maintainability.

SDR Common View on Generic Signals for Time Transfer Applications

This paper presents a new time transfer system that works with any radio signal with sufficient bandwidth, regardless of its content and modulation, by adopting the common view approach. This system, based on a network client-server architecture with SDR receivers offers a number of advantages. It can compare remote atomic clocks or disseminate reference time scales to end users with precision at the level of tens of nanoseconds. Its improved features in terms of flexibility, robustness, reliability, and security will potentially make positive contributions in the field of time transfer, as an alternative or complement to existing methods.
