TriG - A GNSS Precise Orbit and Radio Occultation Space Receiver
The GPS radio occultation (RO) technique [1] produces measurements in the ionosphere and neutral atmosphere [2] that contribute to monitoring space weather and climate change; and improving operational weather prediction. The high accuracy of RO soundings, traceable to SI standards, makes them ideal climate benchmark observations. For weather applications, RO observations improve the accuracy o...
متن کاملTesting Climate Models Using Infrared Spectra and GNSS Radio Occultation
The Climate Absolute Radiance and Refractivity Observatory will be a climate benchmarking mission intended to include instruments for measuring Earth’s atmospheric refractivity by GNSS radio occultation (RO), high spectral resolution thermal infrared spectra emitted from the Earth, and the spectrally resolved reflected shortwave spectrum. Climate benchmarking is necessary to establish a record ...
متن کاملAnalysis of reflections in GNSS radio occultation measurements using the phase matching amplitude
It is well-known that in the presence of superrefractive layers in the lower-tropospheric inversion of GNSS radio occultation (RO) measurements using the Abel transform yields biased refractivity profiles. As such it is problematic to reconstruct the true refractivity from the RO signal. Additional information about this lower region of the atmosphere might be embedded in reflected parts of the...
متن کاملMultiple phase screen modeling of ionospheric scintillation along radio occultation raypaths
[1] We present the Radio Occultation Scintillation Simulator (ROSS), which uses the multiple phase screen method (MPS) to simulate the forward scatter of radio waves by irregularities in the equatorial ionosphere during radio occultation experiments. ROSS simulates propagation through equatorial plasma bubbles which are modeled as homogeneous electron density fluctuations modulated by a Chapman...
متن کاملLAGRANGE RO: A GNSS Receiver for Radio Occultation
A GPS Radio Occultation occurs when a transmitting GPS satellite, setting or rising behind the Earth limb, is viewed by a LEO satellite that carries on board a space-qualified GPS receiver. In this way, it is provided a vertical sounding of the atmosphere exploiting the relative motion between the GPS and the LEO satellites. The technique proved to be particularly precise in retrieving temperat...
