HEOL DESIGN offers complete Master+Slave PTP solutions, with sub-microsecond accuracy. The GPS or GPS+GLONASS/GALILEO/BEIDOU receiver enables very fast start-up times, as it is based on a high performance chipset with -160dBm sensitivity and T-RAIM algorithm, it delivers extremely accurate timing information, even in poor signal level conditions (indoor, urban canyons and signal obscured environments).
Precision Time Protocol (IEEE1588) has been implemented for applications that need sub-microsecond synchronization, in Unicast or Multicast, one step or two step.
As an option, a low drift OCXO can be integrated, with Holdover capabilities (when satellites are lost, or synchronization from Master is lost), and battery powered RTC Clock, to startup with no GNSS satellite...
