Web6 mrt. 2015 · It is an advanced model of an “ionospheric heater.” (The ionosphere is the electrically-charged sphere surrounding Earth’s upper atmosphere. It ranges between 40 to 60 miles above the surface of the Earth.) Put simply, the apparatus for HAARP is a reversal of a radio telescope; antenna send out signals instead of receiving. Web20 jan. 2016 · Using GNSS observable from some stations in the Asia-Pacific area, the carrier-to-noise ratio (CNR) and multipath combinations of BeiDou Navigation Satellite System (BDS), as well as their variations with time and/or elevation were investigated and compared with those of GPS and Galileo. Provided the same elevation, the CNR of B1 …
