Special Issue Information

Dear Colleagues,

Recently, we have witnessed rapidly growing interest in the potential use of LEO opportunistic signals in positioning, navigation and timing (PNT) applications. Considered as an alternative to GNSS signals, their diversity of applications in aviation- and avionics-based GNSS information (PNT) is being revisited to develop novel and innovative conceptual designs for “Next-GEN Avionics Communication, Navigation and Surveillance”. With the existing LEO constellations, in addition to the mega constellations in Orbit and planned to be completed in the future, a Universal framework for LEO-PNT Information accessibility and integration into future generations of avionics systems becomes a serious challenge and objective in aviation. Ensuring positioning, navigation and timing for communications, navigation and surveillance using LEO opportunistic signals is leading to a new era in embedded system and technology design for onboard future airlines (UAMs, UAVs, etc.).

This Special Issue, therefore, will put together original research and review articles on recent advances, technologies, solutions, applications, and new challenges in the field of “LEO-PNT Based Next-GEN Avionics Communication, Navigation and Surveillance”.

Potential topics include but are not limited to the following:

  • Next-GEN communication, navigation and surveillance;
  • NEXT-LEO Receiver design and certification;
  • Hybrid LEO/GNSS receiver architectures;
  • LEO-PNT CNS signal processing;
  • Multiple LEO-PNT Information fusion;
  • LEO signals opportunity-based navigation;
  • LEO/GNSS Data fusion for resilient CNS systems;
  • Information fusion of Multiple LEO SoOP;
  • LEO Receiver design Integration with NEXT-GEN avionics;
  • Kalman filtering applied to LEO SoOP processing;
  • Doppler/Doppler rate-based positioning;
  • LEO SOOP/INS Integrated navigation systems;
  • Antenna design for LEO-PNT and surveillance;
  • Hardware constraints and miniaturization for embedded avionics systems.

The advancement of low-earth-orbit (LEO) communication constellations has revitalized interest in Doppler-based positioning. However, conventional Doppler positioning algorithms struggle with dynamic receivers under unknown initial states due to the inherent nonlinearity of the observation model. To address this challenge, we propose an improved least-squares-based algorithm that decouples the estimation of position and velocity, enabling robust positioning from a zero initial state. Simulation results demonstrate that the proposed method achieves meter-level positioning accuracy and decimeter-per-second velocity accuracy under various dynamic scenarios, including high-speed motion. This approach establishes a viable framework for real-time navigation in GNSS-challenged environments using LEO signals. Full article
