Key Features

syncboxRED is a single box GPS serial time receiver system, providing high accuracy serial data for single system timing and PC time synchronisation applications. The receiver is suitable for external and internal installation (when mounted close to a window) due to the high sensitivity of the GPS reception circuit. The antenna system is supplied with wall mount fixings.

GPS as a time reference

The Global Positioning System (GPS) is a radio based, all weather satellite navigation system used in many applications to provide accurate positional information. GPS also provides a very accurate calculation of time. In suitably designed receiver systems, the time source can be harnessed to provide internal timing signal offsets in the tens of nanoseconds range. Taking into account signal processing and driver propagation delays, timing data is available on the output pins of the syncboxRED accurate to within 1 µsec of UTC.

High sensitivity

The syncboxRED GPS Time Receiver incorporates an advanced high sensitivity GPS engine with class leading interference rejection and low noise operation. This enables the system to acquire a full time and date lock extremely quickly under normal signal strength conditions, and also facilitates full time and date lock in urban canyon areas where GPS signals may not have previously been reliably available.

RS232 data output for PC time synchronisation

The syncboxRED has a single RS232 level serial output providing time and date data for the synchronisation of a single device or for PC time synchronisation. The system is available with different software versions providing serial output messages in different formats, including messages compatible with standard NTP ref clock drivers. Special software versions providing serial output formats to your specific requirements are available upon request. The system also has a single PPS output at RS232 signal levels.

Time output referenced to UTC or local time

Software versions are available to output time information referenced to UTC or one of 61 different time zones. Where required, the syncboxRED performs seasonal time change adjustments automatically.
