An In-Depth Analysis of the 2026 Strait of Hormuz GNSS Jamming and Spoofing Incident and the Mechanisms Underlying Satellite Navigation Signal Vulnerabilities. This article details how Hongke’s GNSS simulator testing solutions precisely replicate extreme electromagnetic suppression, relay, and generative spoofing attack scenarios in the laboratory, helping engineers evaluate receiver anti-jamming performance and comprehensively empowering the safety verification of high-precision positioning and navigation for autonomous vehicles, drones, and robotic systems.

In Global Navigation Satellite System (GNSS) radio frequency simulation testing, Gaussian white noise (AWGN) is typically regarded as the baseline configuration for replicating real-world electromagnetic environments. However, engineering practice has shown that the impact of noise on a receiver’s positioning performance does not follow a linear, monotonic relationship. Based on actual measurement data from the DST GNSS simulator, this paper analyzes the physical mechanisms of Gaussian noise in Kalman filters, correlator jitter, and phase-locked loops, and provides a scientific testing guide for configuring simulation noise.

In the GNSS field, many companies remain stuck at the “application-layer implementer” stage and struggle to meet challenges such as drone swarm coordination, high-precision positioning in extreme environments, and anti-jamming encrypted communications. Deste (a Hongke partner) has broken through the limitations of superficial integration to build end-to-end technical depth spanning “underlying technology—testing and validation—complex scenario applications.” This article provides an in-depth analysis of how Destar, through its strategic portfolio of patents and software copyrights, has built a GNSS technology moat from the “ground up.”

An In-Depth Analysis of Enhanced NMEA Playback Technology. By combining messages such as GGA, GSV, and GSA with carrier-to-noise ratio data, this technology accurately recreates real-world GNSS road scenarios—including urban canyons and multipath interference—overcoming the limitations of traditional NMEA and IQ/RF recording methods, and enabling the validation of positioning algorithms for autonomous driving and the low-altitude economy.

To address the need for high-precision navigation in the low-altitude economy (UAV/eVTOL) in Hong Kong and Southeast Asia, Hongke has launched the all-new Skydel Anechoic spatial physical field and phase angle simulation system. Breaking free from the limitations of traditional RF cables, this system perfectly replicates a three-dimensional sky environment within a microwave anechoic chamber (OTA), enabling precise verification of CRPA antenna interference resistance, antenna radome phase distortion, and spatial angle of arrival (AoA)!

With the tightening of in-vehicle terminals and intelligent transportation standards (e.g. GB/T 45086), it is difficult to cope with manual testing. HONGKE experts deeply analyze how AutoGNSS automated test platform can realize full chain traceability and data traceability, speeding up the whole cycle of research and development by 4-5 times, and completely eliminating the technological threshold of complex GNSS simulation tests!
