First combined COMPASS/BeiDou-2 and GPS positioning results in Australia. Part I: single-receiver and relative code-only positioning

, 2014
China's BeiDou-2/COMPASS is expected to deliver global Positioning, Navigation and Timing (PNT) services by 2020. Australia is already a beneficiary of the regional BeiDou configuration, as enough satellites are available to perform PNT.

Model‐Based Analysis of Ionospheric TEC Disturbances Over China and Adjacent Regions During the May 2024 Super Geomagnetic Storm

Space Weather, Volume 24, Issue 8, August 2026.
Abstract This study uses observation data from multi‐constellation (GPS/GLONASS/Galileo/BeiDou) ground‐based Global Navigation Satellite Systems (GNSS) networks and a non‐integrated spherical harmonic function modeling methodology to develop an ionospheric Total Electron Content (TEC) model with high spatiotemporal resolution (1° × 1° in longitude and ...

Analysis of the Charge Structure and Lightning Activity During a Severe Beijing Thunderstorm via an Innovative Balloon‐Borne 3D Electric Field Observation System

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract We developed an innovative balloon‐borne observation system based on China's BeiDou sounding platform that integrates a three‐axis electric field sensor for in‐cloud measurements of thunderstorm electrification. On 13 May 2025, this system was deployed during a severe convective storm over Beijing. In combination with multisource observations,
