GPS8 Time & Frequency Standard
GPS8plus Time & Frequency Standard
The GPS8 Time & Frequency Standard from Time & Frequency Solutions is a precision time & frequency standard that uses the Global Positioning System (GPS) as a reference to provide a range of output and interface options. It is designed for use in any applications where reliable time and frequency information is required, e.g. Telecommunications, Power Utility and Military Communications applications.
The GPS8plus model has an enhanced front panel with alphanumeric display and 5-segment button for easy configuration
- GPS synchronisation
- Crystal oscillator for high frequency stability with option to upgrade
- 1PPS, Pulse & Timecode outputs
- 1 U high standard 19” rack mount
- Equipment configuration stored in non-volatile memory
- GPS8plus has same functionality as GPS8, but allows easy configuration via the enhanced front panel (see image)
- FSYNC output capability
The GPS8 Time & Frequency Standard utilises a high performance 12-channel C/A code GPS receiver. An automatic position-averaging feature enables the best use of GPS when operating in a fixed location.The GPS8 Time & Frequency Standard is fitted with an internal oscillator in order that time information can be accurately maintained when no satellites are tracked. The internal oscillator also provides a highly stable frequency standard. An advanced, patented algorithm using the time signal from GPS provides optimal control of the internal oscillator ensuring that the highest frequency accuracy is obtained.
Four isolated sine wave and two square wave outputs, grouped in pairs, may be configured to provide 1MHz, 5MHz or 10MHz frequency outputs from the disciplined oscillator. Alternatively, these outputs can be configured to provide Telecomm Output references (1.544MHz or 2.048MHz) allowing the GPS8 to be used a telecommunications primary reference clock compliant with G.703 sections 6 and 10. An 8kHz “frame” pulse is provided to complement the Telecomm outputs.
Front panel LEDs provide status information, and standard serial time code outputs allow time synchronisation to be distributed to computers, displays, and other equipment requiring precision time. These serial data ports may be used both for control of the GPS8, as well as the output of time. A standard 1PPS time mark corrected to UTC is provided for synchronising of calibrating user equipment.
