A study of Ka-Band Signal Attenuation at Umiam, Meghalaya with ISRO’s GSAT-14 Satellite
Abstract
A study at NE-SAC, Umiam of Rain Attenuation to Ka-Band signals has been made with ISRO’s GSAT-14 Satellite carrying two Ka-Band beacons at 20.2 Ghz and 30.5 Ghz and with the help of instruments like High Gain receiving antennas; Humidity Profiler Radiometer, Tipping Bucket Rain Gauge , GPS antenna etc.. The study has been a joint collaboration of ISRO and CNES/ONERA, the French Aerospace Lab. The study comprises simultaneous signal attenuation and rainfall recording of a time period ranging from Pre-Monsoon to Post –Monsoon season at Umiam, from March to October for the year 2016.
