Also, I checked the start/stop times on the DPOS report, which states that the file was collected from 8:31 p.m. June 12 to 4:44 a.m. June 13. Assuming those times are UTC, I would have had to run the base from 1:31 p.m. to 9:44 p.m. local time (PDT). This point is on the roof of my house, and I know I never retrieved the base in the dark. Furthermore, the DPOS report position (which is somewhat sloppy at about 0.1' peak-to-peak) plots about 27' southeast of the actual location as verified by multiple OPUS and DPOS solutions.
