Deep Learning Driven Detection of Tsunami Related Internal GravityWaves: a path towards open-ocean natural hazards detection [PDF]
arXiv, 2023 Tsunamis can trigger internal gravity waves (IGWs) in the ionosphere, perturbing the Total Electron Content (TEC) - referred to as Traveling Ionospheric Disturbances (TIDs) that are detectable through the Global Navigation Satellite System (GNSS). The GNSS are constellations of satellites providing signals from Earth orbit - Europe's Galileo, the ...

A BeiDou Signal Acquisition Approach Using Variable Length Data Accumulation based on Signal Delay and Multiplication [PDF]
, 2020 The secondary modulation with the NeumannHoffman code increases the possibility of bit sign transition. Unlike other GNSS signals, there is no pilot component for synchronization in BeiDou B1/B3 signals, which increases the complexity in acquisition. A previous study has shown that the delay and multiplication (DAM) method is able to eliminate the bit ...

BeiDou-G2: Past and Present [PDF]
arXiv, 2022 In January 2022, the defunct satellite BeiDou-G2 was pulled out of geostationary orbit by Shijian-21 to a graveyard orbit. For safe docking and operation, it was necessary to determine the rotation state in advance. In this paper, we show the evolution of the rotation of the BeiDou-G2 satellite based on the photometry observation data for the past 10 ...
