Elettronika GPS Clock Source

The GPS Clock Source is the last GPS synchronisation product of Elettronika targeting the wireless infrastructure. This GPS clock combines an 8-channel GPS receiver, high quality ovenized oscillator and a 4 way distribution for 10MHZ and 1PPS signals. Among its uses are synchronising the DVB infrastructure.

The GPS Clock Source outputs 4 10 MHz reference signals and 4 1PPS signals with an over-determined solution synchronised to GPS or UTC time. The 10 MHz reference accommodates applications requiring sub-microsecond timing.

The GPS receiver is driven directly by the 10 MHz output signal of the oscillator. This is calibrated against the incoming GPS signal, with the resulting clock and frequency measurements fed into the oscillator frequency control algorithm.

The T-RAIM (Time-Receiver Autonomous Integrity Monitor) algorithm is used to monitor satellites to ensure signal integrity.

The clock continues to distribute time and frequency signals even if the GPS input signal is lost. Furthermore, learning from its behaviour in different situations (effect attributed to aging and to temperature variations) while the GPS reference signal is present, the frequency driver improves on the accuracy of time and frequency distribution when the GPS signal is lost.

Housed in a 19" - 1U rack, the equipment has a very compact structure. A display on front panel helps the user to program the working modes and to read the GPS status. Leds on front panel gives to the operator a quick view of the status.

The GPS Clock Source can be controlled by remote by a wired telemetry connector or by serial (RS232 on front panel or RS485 on rear panel).
