NTS-9000
5071A Support Upgrade
Elproma SafeTime NTS-9000 can be synchronised directly to Cesium 5071A taking both 1PPS and ToD (UTC) reference via D-SUB9 rs232 interface. The NTS-9000 is a value-add upgrade package (available separately). After firmware update the NTS-5000 is upgraded to NTS-9000. Since year 2020, this option is also available for NTS-3000 and NTS-4000 too. As a result, Elproma delivers to market, a ready to use single cesium time server hybrid system, so-called NTS-9000. This system is available on request only and requiring long term prefatory calibration to atomic cesium clock 5071A

The server has a very fast (less than 0.5ms +/- 1ppm) Time To First Fix TTFF synchronization startup. The GNSS receiver accuracy is better than 15ns (at 2 sigma). The server supports cryptographic authentication for NTP. Holdover mode ensures synchronization accuracy is better than 4ms in the first hour. After 24h the max. holdover error is not bigger than 100ms on server output. When normally operating its accuracy is better than 200 ns.

Microsoft Windows allows you by defaults to synchronise your PC-clock to one NTP server only. It also has serious limitations because it is SNTP client, not NTP. Elproma has prepared 100% ref. NTP Windows compilation basis on source C code released on www.ntp.org. Now, you can use it FREE and all the same on Windows like you do on Linux NTP distribution.
TSA RFC 3161 - Qualified Time stamping Server With built-in HSM Hardware Security Module.
Any place where consequences may have a financial impact or concern the people safety, or when Industry 4.0 automation performs functions under the penalty of law, the qualified time stamping is no less important than synchronization, because it provides cryptographic non-repudiation of the event.
STAS – the Synchronization Time Audit System is SCADA class monitoring management system with built-in time audit facility. System is scalable, and it can operate on virtual machine (VM) or can run on real physical server computer. This system can simultaneously maintain thousands of devices just using as small as 2x displays only. Originally STAS has been developed for TELEORGIN Elproma division to support huge population of 100,000 remote IP-devices operating globally worldwide. The minimum hardware requirement for VM deployment is: CPU 8x core, RAM 64GB, HD 4TB (SSD RAID5 or SAS 10K). The software basis on Linux Ubuntu Server (x64) v18.04.
