Orolia, a provider of resilient positioning, navigation and timing (PNT) solutions, announced that its SecureSync time and synchronization servers have been selected to support enroute radar systems across the U.S.
The selection comes as part of the Federal Aviation Administration’s (FAA) move towards a Next Generation Air Transportation System (NextGen). NextGen is about halfway through a multi-year investment and implementation plan.
The FAA plans to keep rolling out NextGen technologies, procedures and policies through 2025/2030 and beyond.
While NextGen will rely heavily upon GNSS to increase capacity, efficiency, and safety in the National Air Space (NAS), many technologies including legacies such as radar will be integrated into the system for maximum robustness to error and disruption.
The FAA employs a variety of radar types for short-, medium- and long-range air traffic control requirements. These diverse radars require different types of timing signals and outputs to suit their operations.
SecureSync. Orolia’s SecureSync provides the necessary timing outputs and signals to meet these requirements. The time server’s ability to provide resilient, accurate and reliable timestamps for the data that it receives from radars is used to quickly organize the data for the aircraft control user interface.
The only time and synchronization device approved by the Defense Information Systems Agency (DISA) for use in U.S. Government networks, Orolia’s SecureSync provides reliability, security and flexibility to synchronize critical aviation operations. SecureSync combines multi-GPS/GNSS signal synchronization, options for alternative signals and BroadShield GPS anti-jamming/spoofing protection for transportation systems. SecureSync combines Orolia’s precision master clock technology and secure network-centric approach with a compact modular hardware design.
The FAA selected Orolia for the competitive program based on its proven timing and synchronization technology and its ability to offer multiple output options as commercial off-the-shelf (COTS) products that do not require additional research and development time or investment.
“Consistently accurate timestamps and the synchronization of thousands of real-time flight data points are essential for safe and efficient enroute air traffic operations,” said Jean-Yves Courtois, CEO of Orolia. “Orolia is proud to support the FAA’s radar data and aircraft control user interface requirements to improve air travel services nationwide.”
More About the SecureSync COTS Product. Built-in time and frequency functions are extended with up to 6 input/output modules. Included with the base unit is a 1PPS timing signal aligned to a 10 MHz frequency signal without any 10 MHz phase discontinuity.
A variety of internal oscillators are available, depending on requirements for holdover and phase noise. On-board clocks synchronize to a variety of external references as standard, factory-installed or upgradable options.
Users may add alternate signals of opportunity to GPS or GNSS input references to improve resilience, or use them for indoor applications and choose from a variety of option cards to add to configuration of timing signals, including additional 1PPS, 10 MHz, time code (IRIG, ASCII, HaveQuick), other frequencies (5 MHz, 2.048 MHz, 1.544 MHz), telecom T1/E1 data rates, multi-network NTP and PTP. Modules can be customized for exact requirements.
To support network time synchronization, SecureSync supports the latest features of network time protocol (NTP) and precision time protocol (PTP, IEEE-1588v2). An optional multi-port NTP configuration allows for operation across 4 isolated LAN segments. Up to 6 PTP ports can be added to operate in various PTP deployments.
SecureSync is a security-hardened network appliance designed to meet rigorous network security standards and best practices. It ensures accurate timing through multiple references, tamper-proof management and extensive logging. Robust network protocols are used to allow for easy but secure configuration.
Features can be enabled or disabled based on network policies. Installation is aided by DHCP (IPv4), AUTOCONF (IPv6), and a front-panel keypad and display. The 1 RU chassis supports multi-GNSS (GPS/ Galileo/GLONASS/BeiDou/QZSS) input.
Options include SAASM, supporting L1/ L2, available for authorized users and required for the US DoD, and BroadShield GPS jamming and spoofing detection. The unit is powered by AC on an IEC60320 connector. DC as back-up, or primary, is available.
