 ::''- A concise guide to GPS fieldwork''
-perhaps the most important thing to remember about GPS fieldwork is that with a 24-hour GPS survey you can measure the position of the GPS antenna to within about 2 mm horizontal precision and 6 mm vertical precision, and you can measure the vector between two GPS antennas even more precisely than that. What this means is that the tolerances for setup error are very tight and you have to be very careful. If not, YOU are likely to be the limiting error source in the measurements. It also means that you really can't hide it if you screw up. So do your best if you make a mistake or something odd happens, carefully record it on the log sheet. It is far better to know we have a bad observation than to find out years later.

 ===Where can I find site information?===
 We maintain a [http://gps.alaska.edu/gps GPS Site Database] that in theory stores site information from all the GPS sites we use. In practice, some are missing, but the database is mostly complete for Alaska and environs. You can search the database by 4 characeter ID, or radial or rectangular searches, and other ways as well. To access the database, you need a login and password, and for that you need to ask Jeff.
