We report a preliminary analysis of the impact of Global Navigation Satellite System Reflections (GNSS-R) data on ionospheric monitoring over the oceans. The focus is on a single polar Low Earth Orbiter (LEO) mission exploiting GNSS-R as well as Navigation (GNSS-N) and Occultation (GNSS-O)...
In this report we analyze the feasibility of ionospheric monitoring using GNSS technology. The focus will be on the use of LEO GNSS data, exploiting GNSS Reflections, Navigation and Occultation TEC measurements. In order to attack this question, we have simulated GNSS ionospheric TEC data as it ...
August 2, 2023: Updated azimuth outputs for gnssir and quickLook so that the azimuth of the rising or setting part of the arc is reported rather than the average azimuth, as was done in the older versions. July 7, 2023: The newarcs option had a bug in it: the refraction correction ...
Using this method, the distance between the water surface and a GNSS antenna can be estimated directly, if corrections of the heave and the ship's attitude are considered properly. Suitable segments of a 3-month dataset, gathered aboard a ferry ship operating in the German Bight, were ...
GNSS reflectionsDoppler shiftSignal PowerGrazing elevationsA reflectometry station has been set up in 2013 near Ny-lesund, Svalbard, at 78.9082°N, 11.9031°E. The main goal of the setup is to resolve the spatial and temporal variations in snow and ice cover, based on reflection power ...
GNSS reflections and GPS bistatic radar in particular, has become a popular topic in the GNSS community mainly because of the multitude of new exciting applications it enables. The concept was discovered by accident by a French research group in the early 90's and since then researchers all ...
