Kronos Series 3 Specs

Introducing the Kronos Series 3 Satellite Clock, specifically designed for applications in power systems. Key features include high precision, multi-constellation support, output flexibility, and Ethernet integration. Kronos clocks are backed by the same NovaTech Automation sales and support policies as Orion and Bitronics products.

 

High Precision

The Master Clock supports IEEE1588-2008v.2 grandmaster functionality, and is available with standard temperature controlled crystal oscillator (TCXO) or optional oven controlled crystal oscillator (OCXO). It achieves 20 nano-second max time deviation (with PTP). Antenna cable-delay compensation further enhances accuracy.

 

Multi-Constellation Support

Kronos is more than just a GPS clock; it can lock onto any of the GNSS constellations: GPS, GLONASS, BeiDou, or Galileo. This means more assurance of a fast lock and less time in holdover.

 

Output Flexibility

IEEE1588-2008V.2 (PTPv2)
NTP/SNTP
Unmodulated IRIG-B over twisted pair, coax, or fiber
Modulated IRIG-B over coax
PPS or PPM signals

 

Ethernet Integration

Kronos supports browser-based configuration and SNMP. Can synchronize any ethernet device over PTPv2 and/or NTP/SNTP in a simple or PRP/HSR network.
