The suggestion was:
Whether they develop the means and the motivation to launch a big jammer into orbit over the Pacific basin is something one can only speculate about.
Can you have a big jammer in space? The reason the GNSS signal is so weak is because it has to produce an omni directional signal from 20,000k away using only solar powered batteries. Wouldn’t a jammer in space suffer from the same problems? I never could understand spread spectrum transmission, especially wrt GNSS, but wouldn’t this give GNSS the advantage over a faint noise jammer. eLoran would be a much stronger signal, but we’re still left with the power/distance equations, which favour a nearby jammer over a distant transmitter.
