F53 – GPS Operation Mode
Use function F53 to set the GPS M12 Receiver in Time Mode or Dynamic Mode.
Select “Dynamic Mode” if the position of the receiver is subject to frequent change, or if it is in
continuous motion. For example, use Dynamic Mode when the XL-GPS is used in mobile vehicles such
as ships, land vehicles, or aircraft. With Dynamic Mode selected, the receiver updates the position
information repeatedly to arrive at the best time calculations for a mobile environment.
Select “Time Mode” if the receiver used in a static environment such as a server room. With Time Mode,
the receiver averages the position data over time to determine the antenna position and calculate the
time precisely and accurately.
