Hi Leland,
Don't be surprised if the Probe doesn't pick up anything. Remember the Original GPS modules all had to be recalibrated as they had been setup to allow for time dilation (due to their velocity), but there wasn't any.
Apparently it has to do with the effects of Duality.

I remember something about the mission wanting to be very careful in analyzing the data, so as not to reach any wrong conclusions, and to provided iron clad evidence, to a naturally skeptical scientific community, of the findings, which, no doubt, will be used for many many years to come.
