Oh that's easy then, get him to figure out how to semi-sync with the
secondary GPS frequency, which is what high end surveying equipment
does, you don't need to lock onto the signal, just get close enough to
calculate the atmospheric effects on the L1 signal, and do it cheaply
enough we can get less than 1m accuracy with consumer grade kit :D
