The article reports on the partnership signed by PlantiQ with the U.S. National Oceanic and Atmospheric Administration (NOAA), in which it will provide its signal to noise ratio global navigation satellite system (GNSS)-radio occultation data to the latter....

An analysis of how RO data can be used to determine the strength and location of turbulent regions is presented. This includes the derivation of a model for the power spectrum of the log-amplitude and phase fluctuations of the permittivity (or index of refraction) field. The bulk of the ...
现阶段,单独依赖GNSS设备本身的定位性能并不能满足厘米级高精度定位和完好性的需求,需要各类增强系统(服务)提升其性能。 增强系统的类型有很多,例如差分系统、局域增强系统、地基增强系统、广域增强系统、星基增强系统、传感器增强系统等。从技术角度,增强服务可以分为两大类即观测域(OSR)增强服务和状态空间域(SSR)增强...
We present a 3D variational data assimilation (3D-Var) scheme developed to derive consistent global analysis fields of temperature, specific humidity, and surface pressure from GNSS RO data. The system is based on the assimilation of RO data within 6h time windows into European Centre for Medium...
The GNSS data provides inputs to the control loop of a drone or other autonomous vehicle, allowing it to maintain position, return to home or follow a series of preset waypoints. This is particularly important for waterborne robots such as AUVs and ROVs whose positions can be significantly ...
