User Manual SICLOCK GPS1000 2. Brief Overview 2.1. Function SICLOCK GPS1000 is a modern GPS radio-controlled clock which can be used worldwide for the reception of time signals from the 24 American GPS satellites. At the output of the GPS1000 antenna head a DCF77 time telegram with Greenwich Meantime is available. The advantage of the GPS1000 is that the antenna, GPS receiver and GPS decoder are integrated in the an- tenna head as one unit and there is therefore no need to lay coaxial

User Manual SICLOCK GPS1000 4. Lightning Protection When exterior antennas are used in industrial areas, a reliable lightning protection is of the utmost importance for operating the system safely. The installation of a lightning protection unit alone is not sufficient. The antenna and antenna cable must be in- stalled in such a way that a direct stroke of lightning or flashover in these parts is not possible. Otherwise it would not be possible to prevent the destruction of parts of the

User Manual SICLOCK GPS1000 4.2. Parts of buildings in danger of being struck by lightning The determination of potential areas in danger of being struck by lightning can be done in a very simple way by conjuring up a mental picture of the ball of lightning rolling over all the surfaces and edges of the building to be examined (see Fig 7 and Fig 8). All areas, where the ball of lightning touches surfaces or edges, are in danger of being struck by lightning (shown in red). Fig 7

User Manual SICLOCK GPS1000 4.3. Inducting effect during lightning strikes Another important parameter influencing the choice of antenna location is the induction effect which arises from lightning conductors or building parts where lightning current flows through. When the lightning hits into a lightning conductor, within a few hundred nanoseconds, voltages of several megavolts are built up, which result in conducted currents up to several 10000 amps with correspondingly steep surge pu

This however, means that there is a possible danger of lightning striking. Therefore the location selection criteria in chapter 3.4 are of utmost importance! Concerning the best performance for signal reception, the following points should be taken into account when selecting a suitable location: The

The relative precision is better than 3 µs for both interfaces. The relative precision specifies the maximum deviation of two sequential impulses. The absolute precision is the offset to the atomic clock supplying the whole GPS system. If signals from only four satellites or less are received, a
