Bob, I believe (Tom can confirm this) that surveyor-grade GPS has access to the military-level accuracy that is denied to civilian units. I'm pretty sure there's a high level of encryption on the signal. Surveyor GPS units cost around $30,000, so it's a serious bit of hardware. Considering what it's used for, a high degree of precision is called for.

I don't think there's a particular advantage over EDM, but it's acceptable.
