In most gravity surveys, gravity and position data are usually collected, stored, and processed separately. They are either recorded manually in a field notebook or in the memories of the instruments with subsequent data entry or download to a computer for processing. However, this has several disadvantages; in particular, most instrument interfaces are too crude to continuously monitor the measurement and thus detect problems in the field, such as meter malfunctions. This means that the separate recording of the gravity and position data is prone to problems such as station misidentification, transcription errors, or even missing records.
