GPS antenna
GPS antenna is the main element responsible for vehicle positioning accuracy and quality. FMS500
Light+ units are equipped with internal GPS antennas. To ensure best possible GPS signal reception
and evaluating GPS signal character, there are strict requirements for correct installation of the tracking
unit:
The accordingly marked side of the device must be invariably directed to the sky. The device
must be oriented horizontally (not at an angle) and oriented with the corresponding side towards
the top.
The device should not be covered with metal sheet or reinforced glass. In vehicles with standard
glass (e.g., without built-in heating elements).
Fixing of the device must be stable and immobile, providing for the installation durability. It is
necessary to take into account events, which may lead to loss of device stability, to select the
mounting location and methods that would allow to avoid these factors.
GSM antenna
GSM antenna is responsible for transfer of collected data and connection with central server. Good
antenna’s performance is the key element in obtaining information from the device. FMS500 Light+
series trackers are equipped with internal GSM antennas.
GSM antenna does not require orientation to open sky; however you should be aware that metal
elements weaken the GSM signal. It is also necessary to take into account the emission of the antenna’s
high frequency radio waves, which may interfere with operation of electronic devices.
