CHALLENGES & SOLUTIONS

CHALLENGE: SERTEL Multi Constellation Reception & MULTIPLE REDUNDANCY SOLUTIONS

Time Synchronisation using telecommunications backhaul as redundant source of time. Sources with L1/L2/L5 bands of communication through various sources act as prevention from rick of GNSS spoofing and Jamming. Currently many power & utility companies are looking for solutions to ensure proper Time Synchronisation even during such unavoidable outages of GNSS source. Sertel’s innovative reception solutions involve backhauls from various GNSS sources for redundancy.

SOLUTION: MULTI CONSTELLATION GPS,GLONASS,IRNSS,BIDEU,GALILEO- ALGORITHMS FOR REDUNDANCY

Sertel’s GNSS solutions offers a range of products that have been designed and built for GNSS redundancy in mind. All products have built in redundancy to acquire satellite information from various GNSS sources added with backhaul local oscillators which can provide a high precision holdover limits.

This ensures all our Time protocols generated are absolutely highly precise and in Synchronisation with various GNSS sources with reliable redundancy built in for Synchronisation.

CHALLENGE: SERTEL TIME SYNC OPERATION WITHOUT DISRUPTION

Reliability, Secure & Non-stop these Sertel’s Time Sync products guaranteed features which are well tested and experienced by all our customers while integrating with their products.

Transmission & Distribution operators always observe that due to various reasons Time Signals such as NTP/SNTP do not provide them accurate sequence of event monitoring due to issues with settings, network latencies.

Similarly it is also observed that effect of transient in low voltage unbalanced IRIGB Signals has always lead to corruption in time signals synchronising Protection & Control devices in Station Bus, Process Bus.

SOLUTION: SEEMLESS INTEGRATION – HIGHLY TIME CRITICAL IRIGB HUBs, BOOSTERs, FSDA- ABSOLUTE REALTIME ACCURACY

Sertel’s products are bare metal stacks driven with a completely customised Sertel OS working on highly time critical time ticks. This has always guaranteed Reliable and Secure time dissemination to all IEDs to utmost accuracy.

Our Ethernet based solution is highly customised for time critical application with maximum throughput.

Our Isolated Timing Repeater with Isolated and balanced TTL outputs or Multimode fiber outputs can connect to Protection and Control IED’s. This prevents the formation of ground loops, mitigating against transients and induced voltage, and ensuring transients affecting one IED do not propagate to other IED’s connected to the same bus. In addition to distributing TTL or unmodulated IRIG-B over fiber, the Isolated Timing repeater can also convert to AM IRIG-B at the same time. The Combination of Tekron’s Clocks and Isolated Timing Repeaters also typically simplifies and reduces IRIG-B cabling and allows for future expansion of the IRIG-B bus with minimal disruption.
