发明名称 ANTENNA USED IN A TRACKING SYSTEM
摘要 Disclosed is a multiple antenna, and/or gimbaled antenna system mounting system (Figures 2A, 2B, 3A) for maintaining electromagnetic signal reception means of an antenna system present in a remote unit in a global positioning system (GPS) based system (Figure B) for continuous electronic monitoring and tracking of monitored individual(s) from a central control station (CCS), in an essentially constant desired orientation with respect to an earth orbiting satellite source of electromagnetic signals , when, in use, change occurs in the orientation of a structural frame element of the remote unit to which the antenna system is, via the multiple and/or gimbaled antenna system mounting system (Figures 2A, 2B, 3A), mounted.
