The Septentrio mosaic-H GNSS receiver is a compact, 448-channel, multi-constellation module designed to solve weaknesses of RTK, PPP, and PPP-RTK by providing centimeter-level accuracy, fast convergence, and advanced interference protection.

Introduction

In GNSS, the limitations of RTK, PPP, and PPP-RTK affect performance in long-distance, global, high-speed, and interference-heavy environments.

GNSS Technology Challenges

Limitations of RTK, PPP, and PPP-RTK

In GNSS, RTK, PPP, and PPP-RTK each have strengths and limitations related to distance, convergence time, and atmospheric sensitivity.

Environmental & Electromagnetic Issues

Urban canyons, UAVs, high-voltage corridors, and radio interference can cause signal loss, drifting, and reinitialization.
