GPS synchronisation
Immunity to GPS rollover
All over the world, time synchronisation can be ensured via a network of 24 satellites part of the GPS system.
The GPS antenna receives a message every second (time + date), decodes it and sends it to the master clock.
The master clock receiving the UTC message (GMT) must be configurable to adapt to the UTC time to local time (time difference and introduction of summer/winter time changeover for the country if necessary). The time setting of receiver clocks is fully automatic.
General features:► 12-channel receiver L1 = 1 575 MHz.
► Data standard : NMEA 0183
► Data transmission: RS485, 4800 bauds, 8 data bits, 1 stop bit, no parity.
► The antenna delivers every second the time message ZDA then GGA.
► Power supply: 5 to 15 V DC (from the SIGMA or the system to be synchronised).
► Horizontal and outdoor installation on the roof or on a mast.
► Possibility to install the antenna behind a window or under a plastic roof.
► Connection to the system to be synchronised with one single cable.
► Cable is 4 wires section 0.25 mm², 20 m provided with the antenna.
► Grey ABS casing with swivelling support to point the sky, fixing with 1 screw Ø 4 mm.
► Operating temperature: -30 to +70 °C.
► Storage temperature: -40 to +85 °C.
► IP65, IK04 protection.

Operation:
► A yellow LED indicates the operation of the antenna.
► The LED flashes every second when the antenna is synchronised.
► The LED remains on when the antenna is not synchronised.
► The LED is off, if the antenna is not supplied with power.
► The LED is visible from under.
