Today was another long day, getting out to survey the area we are using for satellite altimetry validation. Above, the route we drove with the GPS running. We had a false start when our base-station GPS acted up, but managed to get back out and running by early afternoon. Of course, this meant that we would be having another late night, since we had a finite amount of GPS surveying to do. By the end of it, we were ready to get inside!
