> Imagine yourself wearing a cap that's little too small and half-transparent on the edges, walking on fresh snow, surrounded by snow mounds, trying to spot something on one of the hilltops nearby. So the cap mostly protects you from direct jamming signal, but reflections and bleed are still painful.
The usual answer, then, would be a polarized filter and a more narrow aperture (e.g. goggles). The narrower the FOV, the less risk of glare.
That does mean an antenna will have to actively keep itself pointed at a moving point in the sky, but with GPS, a compass, a clock, and each satellite's orbital parameters, that should be a solvable problem.
The harder problem would be for the satellite to pick out the signal coming back from the ground without having to limit itself to a single ground station.
