Wanted to add a bit to the conversation. At least in a number of older GPS receivers circa 1989-1994 the LO was indeed locked to a 10 MHz reference. These were the typical separate mixer and antenna systems. The first LO was 1500 MHz. That is an expensive way to go so I can see why whats described here is attractive to lowering costs.
