Then feel free to try and navigate Australia using only ground based systems. You won’t get far.
The topic says “VOR Navigation”.
I don’t know what you are trying to say. Perhaps you should read up on the infrastructure plan I linked which clearly stated that a ground-based system will be retained - i.e. VORs.
I am very confused about what VOR is and it’s meaning.
It stands for very high frequency omnidirectional range. Roughly a transmitter that sends out a circular VHF radio signal that “rotates” 30 times a second. The signal has a varying frequency and a timing frequency as well as identification Morse signal (and maybe a voice signal too).
The VOR receiver on a plane tunes to the frequency of a station (usually at an airport) and the receiver will work out a “radial” i.e. the direction to that station and from that you can get a fix. Using two stations you get your location by triangulation and a heading compared to magnetic north.
It was the main navigation aid from just before WWII up until GPS was widely used and was the basis for all the skyways set up world wide.

When I started IFR training for the second lesson the Instructor had me work out the radial from a VOR station about 40 miles away to a specific landmark north of the airport.
That radial was set and after takeoff I was to intercept the radial and fly along it until we were overhead the VOR.
The Instructor then spun the VOR around and had me fly along a specific radial for 15 minutes, then he asked where we were.
A check on the ADF at the airport gave us the distance and where a radial of that distance intercepted the VOR radial it gave us one of two possible positions.

There are barely any VOR stations left. It’s for the best, gps is so much better.
True, but its always good to have a contingency plan.

Remember it all too well.
