The GPS antenna with an integrated receiver has to be installed outside for satellite visibility. DC power feed for the receiver is supplied through the combined power and data cable. The GPS antenna is connected to the Sync in port on the System Module front panel.
FYGA GPS Antenna Kit
The Flexi Multiradio LTE BTS uses GPS as a source for frequency and time synchronization. A GPS antenna with an integrated receiver is installed outside for satellite visibility, and is directly connected to the System Module. The GPS antenna with the integrated receiver connected to Sync ln is illustrated in the figure GPS antenna with an integrated receiver.
*combined power/data cables:
Note: The DC power feed (12 V DC) for the receiver is supplied through the following
• FYHA up to 100m
• FYHB up to 30m
A FYEA GPS Surge Protector Kit surge protector is available as an optional unit to protect the System Module from transient voltage and current spikes. lt is installed to the GPS antenna line. The surge protector is particularly useful in locations with a high lightning risk.
Satellite visibility
Note that a 180° clear sky view is the optimum case from the signal quality and accuracy point of view. If the clear sky view is smaller than 180° (for example urban canyons), the GPS receiver operation may suffer from poor GPS satellite visibility, depending on the sky view angle and location on the globe (especially latitude). The GPS receiver may be operational, especially after the survey, even with smaller than a 180° sky view, however, this cannot be guaranteed. Furthermore, the survey time may be longer and the accuracy of the PPS signal poorer than with a full 180° sky visibility.
