A space tracking station was operated from 1964 to 1965, and in the 21st century the Swedish Space Corporation's Universal Space Network again established a remote ground station for space tracking and communications, now consisting of two 13-meter parabolic antennas on the east side of South Point Road.[20] Also at Ka Lae are the large shortwave radio antennas of World Harvest Radio International, which used callsign KWHR until 2009.[21]
