Today I spent 45 minutes talking on the phone with our GPS guy back in the States, he managed to stay up till 1AM helping me. The good news is that he helped me fix a lot of the problems that have been coming up. We are now within 20cm on the vertical axis and within 10cm on the horizontal axis. So tomorrow the GPS will be ready to go. In other news Scottie is down 10cm today in the room of the Persian building and he has a floor level. There is broken pottery and basalt objects, I’ll update with pictures of the room tomorrow.
