A reader has shared that MEV (Bronkhorstpruit VOR) and HBV (Hartbeespoortdam VOR) have both disappeared.
The picture shows the state of GWV is the VOR (navigational beacon) on the border between SA and Zim. RNAV point (Satellite/GPS nav point)is UTULI.
So these ground based NAV sites are problematic. Then you have the radio sites where relay transmitters are located. Same problem, vandalism and theft. Throw in loadshedding and yes, a bleak picture. Nowadays you need a backup for a backup.
