Issue Date: | 2017 | Volume: | 2017 XXXIInd General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS) | First Page: | 1 | Abstract: | Low Frequency Aperture Array (LFAA) systems are opening up new frontiers for ground-based radio astronomical instruments. These instruments require advanced measurement procedures and systems for characterization and calibration of their front-end. For this purpose, a test source mounted on an Unmanned Aerial Vehicle (UAV) has been developed in Italy. This system has proven to be a reliable, accurate, portable and effective tool to characterize LFAA systems as demonstrated during measurement campaigns on two Aperture Array Verification Systems for the LFAA of the SKA in the UK and on a LOFAR station in The Netherlands. This contribution gives an overview of these campaigns, the continuous development of the UAV-based measurement system and the envisaged future improvements. | Conference Name: | 2017 XXXIInd General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS) | Conference Place: | Montreal, Canada | Conference Date: | 19-26 August, 2017 | URI: | http://hdl.handle.net/20.500.12386/29157 | URL: | https://ieeexplore.ieee.org/document/8105020 | ISBN: | 978-90-825987-0-4 978-1-5090-4469-6 |
