By "cores" he meant antennas.
With 4 antennas working together (coherent array) you can make an antenna that can detect angle of arrival for any signal (except for blind areas). GPS works by detecting 4 or more signals and lock-in the receiver to all of them, if you can tell apart the approximate location of each transmitter you'll able to tell apart a jammer/spoofer working at ground level vs a satellite in orbit.
That's the basic principle, the algorithm to do that is the important thing.
>inb4 just 4 antennas
You can keep adding more antennas to the same array to improve signal rejection of hostile transmitter or add more bands, some 12 antennas array are actually 2 arrays, 7+5 antennas working for L1 and L2 respectively. Other arrays can have more antennas for different reasons, like track more signals simultaneously. Of course neither side will talk about the topic, not even after the war, it's too autistic and sensitive
