Actually no. Notice that round thing in the middle of the airport? It's called a VOR. Probably an overlay approach.. GPS goes down, you have ground base navs as back up. Honestly that's about as good as it gets. You loose your GPS, you follow the 303 inbound for straight in or cirlce (2780) use DME to catch the 1.2 for the VDP, miss at the VOR.
Check out Hollister, CA. You have nothing but the GPS to rely on.
