Microchip cesium atomic clock provides autonomous precise time

Image: Microchip Technology

Microchip Technology has released the 5071B cesium atomic clock that can perform autonomous timekeeping for months in the event of GNSS denials.

The 5071B is the next-generation commercial cesium clock to the 5071A. The 5071B is available in a three-unit height, 19-inch rackmount enclosure, making it a compact product for environments where it can be easily transported and secured.

The 5071B has upgraded electronic components to address possible obsolescence or non-RoHS circuitry. The clock provides 100 ns holdover for more than two months, maintaining system synchronization when GNSS signals, like GPS, are denied.

As a cesium beam tube product with no deterministic long-term frequency drift, the 5071B provides absolute frequency accuracy of 5E-13 or 500 quadrillionths over all specified environmental conditions for the life of the product. For military applications requiring rapid deployments for system radars, 5E-13 stability eliminates the need for the acquisition of external synchronization sources prior to radiating.

The 5071B is now fully compliant with the Restriction of Hazardous Substances Directive, making this device available in regions where regulatory policies are in place.

Septentrio timing GNSS module now supports Fugro AtomiChron

Image: Septentrio

Septentrio’s compact GNSS timing module, mosaic-T, now supports the AtomiChron timing service from Fugro. The mosaic-T module already includes several layers of security against GNSS jamming and spoofing with AIM+ integrated technology and OSNMA Galileo authentication; however, AtomiChron further strengthens the anti-spoofing security of the mosaic-T receiver by offering navigation message authentication on all four major GNSS constellations.

Fugro AtomiChron includes navigation message authentication, which ensures timing resilience through reception of only genuine GNSS signals. The AtomiChron eliminates time drift caused by clocks counting time at slightly different rates. This achieves sub-nanosecond accuracy and provides extreme stability that surpasses current precision frequency standards. This is a lightweight and scalable solution, which removes the need for atomic clocks in critical infrastructure.

The mosaic-T delivers accurate timing with multi-frequency, multi-constellation GNSS technology and offers dedicated timing features and inputs for time and clock synchronization. AtomiChron capability can be obtained via a software upgrade for new receivers or for receivers which are already operational in the field.

The AtomiChron service is optional and can be activated through Fugro. To find out more about mosaic-T or the secure positioning receivers from Septentrio use the Product Finder tool or contact the Septentrio team.

Safran’s White Rabbit outperforms APNT industry requirements in EU Commission Joint Research Center Test

Image: Safran Navigation & Timing

The Safran Navigation & Timing critical infrastructure solution, White Rabbit, has received high praise in a report published by the European Commission (EC) Joint Research Center (JRC) that evaluates the effectiveness of alternative positioning, navigation and timing (APNT) platforms.

For more than eight months, the commission studied a variety of available solutions to assess the performance of APNT demonstration platforms in a variety of situations where there is signal loss, and a backup system is necessary. The selected solutions were evaluated for precise and robust timing and positioning services in challenging indoor and outdoor environments.

Safran’s White Rabbit is a high-accuracy time and frequency distribution protocol, which combines precise time protocol (PTP) packets with the frequency base of Synchronous Ethernet (SyncE) to provide sub-nanosecond time transfer accuracy over an optical fiber. While the results of the test campaign showed that all APNT platforms under evaluation demonstrated performances in compliance with the requirements set, White Rabbit excelled in its performance.

Safran demonstrated White Rabbit’s ultra-accurate time transfer over fiber optics, its high-performance time generation, resiliency (based on failover and holdover), interoperability, and user-friendly monitoring capabilities.

As stated in the report, Safran demonstrated, “the ability to handle multiple master clock inputs with voting and seamless switchovers. Interconnecting as many NMIs as possible, with possible local atomic clock backups, would result in a very robust and resilient time architecture, independent from GNSS across Europe. The ability to provide resilient and accurate time through the EU communication infrastructure, ideally on the nanosecond level, would also enable robust positioning, using a combination of signals.”

Compact Add-On Board
Provides access to L-band GNSS corrections

LBand RTK Click is a compact add-on featuring the NEO-D9S-00B, a professional-grade, satellite data receiver for L-band corrections from u-blox. Operating in a frequency range from 1,525 MHz to 1,559 MHz, the NEO-D9S-00B decodes the satellite transmission and outputs a correction stream. This enables a high-precision GNSS receiver to reach accuracies down to centimeter-level. An independent stream of correction data, delivered over L-band signals, ensures high availability of position output. LBand RTK Click also uses several mikroBUS pins. In addition, LBand RTK Click contains an SMA antenna for connecting a Mikroe-brand antenna. This antenna easily allows positioning in space, supporting GNSS L-band frequencies. LBand RTK Click implements advanced security features such as signature and anti-jamming mechanisms. It also can be integrated with other GNSS receivers from the u-blox F9 platform.

Centimeters and picoseconds without satellites or atomic clocks
Locata dish antenna pointed back to EU’s JRC, 44 km away, just under the setting sun. The Yagi antenna above is pointed to a cell tower in Como and used to connect the system for remote control and data logging.
Image: Locata

A new European Commission (EC) Technical Report, published after exhaustive and completely independent testing of several candidate A-PNT (Alternative Positioning, Navigation, and Timing) technologies, confirms that Locata has demonstrated positioning and timing performance across every test environment, delivering:
- cm-level positioning accuracy in all tests, indoor and outdoor, under static and kinematic conditions
- picosecond-level time transfer using Locata’s proprietary TimeLoc technology, over multiple media types including RF over distances of more than 105 kilometres and over fibreoptic and/or coaxial cables, without requiring satellites or atomic clocks.
The rigorous scientific test campaign was conducted over a period of eight months by experts from the EC’s Joint Research Centre (JRC) in Italy. Its purpose was to establish the foundations for European navigation and timing policy, including the upcoming European radio navigation plan, in the context of growing concerns about the single-point-of-failure that GPS and other Global Navigation Satellite Systems (GNSS) pose.

According to Locata, their validated capabilities promise to open previously unattainable, satellite-free A-PNT performance for autonomous vehicles, logistics, indoor positioning, critical national infrastructure, and aviation, as well as better levels of synchronization to improve mobile phone and digital data networks.

Locata’s products have been deployed commercially for a decade, delivering cm-level positioning (via sales and IP licenses) to globally recognized partners, including systems now certified for safety-of-life level operation of autonomous vehicles. Prominent government customers include NASA and the United States Air Force, which runs a large Locata network that covers more than 6,500 sq km for aviation use when GPS is being jammed or spoofed.

This performance evaluation assessment was run under a globally-open tender launched by the EC’s Directorate-General for Defence Industry and Space (DEFIS). The tender sought applications from around the world, from every potential candidate claiming they could provide “an alternative to GNSS-based PNT.” More than 30 companies applied, and this number was then down-selected by an expert panel to the seven technologies that were, in the end, independently evaluated. Locata was the only technology that was granted two contract slots, and the only technology that completed every timing and positioning test, in every indoor and outdoor environment, sought by the EU.
