Makita E. R. de Paula Ciencias de la Tierra fading Ionosphere absorption A commercial computer controlled radio receiver has been used to measure signal strength of High Frequency (HF) signalsin order to study the effects of geophysical events on radio communications and to test the system for ionospheric monitoring. Thesystem was installed at the Southern Space Observatory (OES/CRSPE/INPE) in São Martinho da Serra, Brazil (29.43°S, 53.8°W,B = 23350 nT). Initial results show that this system is able to detect ionospheric radio absorption events. The commercial radioreceiver has a computer serial interface, to control the reception frequency in order to acquire the values of the received signalstrength. We describe the system and some initial results on radio absorption events associated to C and M classes of x-ray solarflares. The results suggest the possibility of using this low-cost system to study the daily variation of the lower ionosphereionization and to study events of ionospheric absorption. Long period measurements give statistical information about the magnitudeand time scale of fading, that can be used for planning radio links. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843206 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.43 |
