DESCRIPTION:Speakers: Racheal Athieno (South African National Space Agency
  (SANSA) Space Science)\nHF propagation involves transmission and receptio
 n of radio signals within a frequency range of 3 − 30 MHz. It finds appl
 ications in a number of communication fields such as international short w
 ave broadcasting\, mobile telephone systems\, radio navigation and operati
 on of radar systems.  However\, it depends on the ionosphere which is cons
 tantly varying mainly due changes in the neutral atmosphere which are a co
 nsequence of atmospheric dynamics. In this paper\, we investigate the effe
 ct of atmospheric dynamics on High Frequency (HF) propagation using the co
 -located radars at SANSA Space Science (19.2o E\, 34.4o S)\, Hermanus\, So
 uth Africa. These radars include the HF Doppler radar\,  Ionosonde\, Globa
 l Positioning System (GPS) receiver and GPS Ionospheric Scintillation Tota
 l Electron Content (TEC) Monitor (GISTM).  HF propagation results from the
  HF Doppler radar are presented.  The comparison of results of the HF Dopp
 ler radar with other radars is also included. Results show that radio comm
 unication is affected by atmospheric dynamics which results into signal fa
 ding or at worst signal loss.\n\nhttps://events.saip.org.za/event/7/contri
