IEEE 1588 Protocol for Percision Timing

Posted - July 24, 2019

undefined

Today's advanced military systems include multiple intelligent electronic devices that require millisecond precision levels, some even nanosecond precision. Accuracy and synchronization have become vital requirements, while precision timing increases effectivity, improves monitoring and troubleshooting capabilities.

IEEE 1588, also known as PTPv2 is a protocol used to synchronize clocks throughout a computer network. It is a future-proof solution for data and power utilities because it meets timing accuracy and synchronization requirements of most power systems applications. Synchronization Ethernet (SyncE) achieves 1ms accuracy by using LAN Ethernet advantages.

IEEE 1588 protocol defines three kinds of clocks:

a. Ordinary Clock (OC) - A device with a single network connection, either the source of (master) or destination for (slave) a synchronization reference.

b. Boundary Clock (BC) - Has multiple network connections and can accurately synchronize one network segment to another. A synchronization master is selected for each of the network segments in the system. The root timing reference is called the grandmaster.

c. Transparent Clock (TC) - A multi-port device that forwards precision time protocol messages, measuring the time taken for event messages to pass through the device, and accounts for this residence time by modifying the message, or by sending a separate follow-up message.

Integrated Soldier Power and Data Systems (ISPDS) play an important role in the modern tactical battlefield. The modern warfare in the twenty-first century is becoming a ground for extensive digital data exchange due to the military's requirements for high-speed data and information transfer between soldiers in the field and command centers in real-time. 
The modern soldier has become a source of battlefield intelligence, fully equipped with advanced weapons and communication systems. This demand makes soldiers carry more weight when dismounted. The extra weight and the amount of equipment increases the need for miniaturization and smart integrated energy management solutions in order to engage easily and effectively in the battlefield.
Techaya is unveilling a range of rugged superior lightweight Integrated soldier power and data systems (ISPDS) for the "Next-Gen" soldier in the tactical battlefield:
MILETCH 406 - Portable Communication Grid.
MILETCH 303 - USB3.1 Smart HUB.
MILTECH 402 – PoE Ethernet Switch with Power Distribution (PDU).
MILTECH 404 - Integrated Soldier Power and Data Management System with integrated SOM, open for customer application. 
MILTECH 410 - Integrated Soldier Power and Data Management System with USB3.0 and 1G LAN capabilities.
All units are compact size and low power consumption specifically suited for soldier carry applications.
Techaya solutions are developed to suit frontline forces in the most complex modern battlefield scenarios, meeting military standards such as: MIL-STD-461, MIL-STD-810, MIL-STD-1275, IP68. 

VICTORY Standard and MILTECH 9012C

Posted - May 28, 2019

Today’s combat vehicles are typically deployed with multiple independent systems that have limited ability to share their functionalities or data. Budgetary pressures to reduce cost, requirements for specific networked technologies to improve situational awareness, governmental mandates for advanced GPS technologies, and the underlying (SWaP) constraints of today’s tactical vehicle platforms increased the need for standardization in modern vehicle electronics architectures.

Modern efforts like the U.S. Army’s VICTORY (Vehicle Integration for C4ISR/EW Interoperability) initiative and the European Generic Vehicle Architecture (GVA) are paving the way for global standardization in this area.

These standards are developed to provide an open architecture, allow platform systems to share information, simplify system upgrades and modifications, reduce complexity and costs.

A part of VICTORY compliance is an open In-Vehicle Network based on Ethernet that will connect all C4ISR/EW networked components. Techaya, as an innovator of compact military-grade Ethernet switching and routing solutions and a member of the NATO GVA standard team, endeavors to make sure that the MILTECH products meet the rigorous testing and quality necessary to earn VICTORY and NGVA specification compliance.

We are proud to announce that the MILTECH 9012C was recently awarded VICTORY standard certification by U.S. Army Combat Capabilities Development Command (CCDC) Ground Vehicle Systems Center.

Fiber Optic in Military Applications

Today’s military personnel face new challenges due to the ever-changing battlefield. New military systems depend on fiber optic networks to deliver real-time data. Investing in optical communication systems as a cost-effective network provides essential communications solution, including greater bandwidth for real-time voice, data and video applications.
Optical communication products have the ability to perform better than copper in the following areas:

  • The ability to transport high volumes of data over significant distances up to 120km.
  • Faster data transmission (up to 10 gigabits/second) that accommodates today’s bandwidth-intensive applications.
  • Reduction of SWaP. 
  • Syber protection - Optics, by nature, are immune to electronic countermeasures, as there are no electromagnetic emissions (EMI). When information is transmitted or recived via fiber, there's no electromagnetic signature to alert of traffic on the fiber. 
  • Many fiber optic connectors achieve IP ratings up to IP68, and offer hermetically-sealed fiber interconnects. These connectors are totally dust tight and protect against the prolonged effects of immersion under pressure.

There are numerous data-intensive applications where the advantages of fiber optic pay dividends, including radar installations, EO sensor suites, persistent wide area surveillance, signals intelligence, and more. Discover Techaya fiber products and more.
