- The SR1050 is a GPS synchronised Universal Time code generator, IRIG B coded.
- The equipment is housed in a 19’’ , 1 U rack mount.
- The equipment includes an OCXO oscillator with a long term GPS oscillator disciplining algorithm.
- On the front face, an alphanumeric LCD display, allows time, satellites visibility & operation mode visualisation.
- The status of the system is shown by mean of 3 LED’s (power supply, satellites tracking, locked).
- A six keypads keyboard provide the man machine interface and the monitoring of the equipment.

- The equipment main function are : 
A frequency reference source with amplifier 
A GPS receiver An IRIG B generator
A digital signal generator (frequency & pulses)
An output multiplexer allowing the allocation of the different signal type to the programmable outputs.

- The GPS receiver is an Oncore UT+ MOTOROLA module able to acquire 8 satellites.
- The module delivers a high precision, top second reference.
- The IRIG B generator provides an amplitude modulated 1 kHz analog signal.
- This signal uses the internal frequency source, it’s also automatically phase synchronised on the 1 PPS signal coming from the GPS or from an external source.
- In case of GPS’ time loss, when starting the equipment, the starting hour of the IRIG B generator could be entered using the front face keyboard.
- The rear face of the equipment holds all the input/output signals.

11 connectors are used :
- GPS antenna input, 
- 1 PPS external input, 
- 1 PPS output, 
- Six user’s programmable outputs : 10 MHz sinus, IRIG B, 1 PPS, frequency & TTL pulse (1 PPM, ... )
- RS232 serial output for time frame periodic emission 
- RS232 link for remote control & management of the equipment
