2. GPS module, VK-172. This GPS module uses a u-Blox7 technology. It is a fairly common consumer item and readily available from online stores.
Please ensure both the N9912A and the N9923A has instrument firmware revision A.05.33 and later. This will allow the FieldFox to log GPS information into the built in software.
