 The management, logistics and infrastructure of the tracking stations were under the control of PAA GMRD while electronic equipment, such as the tracking radars, was under the control of RCAS personnel.Some bases, such as those at Antigua and at Chagaramus, Trinidad, were located in populated areas and, in some cases, technical personnel were permitted to bring their families with them.Some tracking stations, such as the one at Ascension Island in the South Atlantic Ocean, were inhospitable and unpopulated and, as a result, it was not feasible for technical personnel to bring their families with them.
