    Net Insight partners with Meinberg on time synchronization solutions

    Net Insight’s sync solution becomes fully PTP-standard compliant with synchronization module for 5G and other mission-critical networks

    NetInsight logoNet Insight has selected Meinberg’s precision time protocol (PTP) software stack — Precision TimeNet — to implement full PTP functionality in all of its platforms.

    The Precision TimeNet solution offers a GNSS-independent delivery of high-accuracy timing across any IP vendor network, which can significantly reduce the cost and rollout times of 5G and other mission-critical networks.

    In 2021, Meinberg also delivered a synchronization module to Net Insight’s Nimbra MSR 300 series, providing full PTP IEEE 1588v2 interoperability and GNSS integration for 5G networks. The new module is part of the Nimbra Time Node, an important component of the Precision TimeNet solution.

    Net Insight licensed the PTP stack from Oregano Systems, owned by Meinberg, to deliver network synchronization for both media and 5G networks. Meinberg leverages Net Insight’s network synchronization capabilities to serve customers across the telecom, fintech, government, and power telecom industries. The expansion into a strategic technology partnership means that both companies will utilize their expertise in time synchronization to deploy solutions that remove the challenges of reliable precision timing over any IP network.

    “The shift to IP is accelerating, making precision timing key to the successful deployment of new applications,” said Heiko Gerstung, managing director of Meinberg. “Net Insight’s Precision TimeNet offers a unique solution on the market that we see a strong and growing need for, across multiple industries. We’re excited to be working with Net Insight, a leader in mission-critical IP transport, to drive innovation and enable our customers to benefit from GNSS-independent time synchronization.”

    “Net Insight has been developing time transfer for nearly two decades, delivering industry-leading time accuracy and resilience over IP networks,” said Per Lindgren, CTO and co-founder at Net Insight. “When expanding our synchronization business into new markets, integrating with the IEEE 1588 PTP standard was key to enhancing our interoperability. Teaming up with Meinberg, a leader in time and frequency synchronization, was the obvious choice.. We’re excited that our joint expertise in IP networking and time synchronization will enable us to reinvent precision timing for our customers.”

    Jackson Labs offers miniature STL LEO receiver

    The STL-2600 STL-capable receiver provides a GNSS-independent low SWaP-C UTC-time and location capability

    Jackson Labs Technologies Inc. (JLT), a designer and manufacturer of GNSS, timing and frequency equipment, has announced the availability of the STL-2600 Satellite Timing and Location (STL) receiver designed in partnership with Satelles Inc., the STL service provider.

    The STL-2600 commercial receiver provides a completely GNSS-independent, low-cost capability to generate UTC nanosecond timing and meters-accurate positioning anywhere in the world. It operates in a way similar to GPS, but without GPS or GNSS. The STL signal has 30-db (1,000 times) higher power compared to GPS signals, allowing the receiver to operate deep indoors independent of any GPS/GNSS signal.

    “Useful for non-GNSS-based E911 location and UTC(NIST) timing applications, the STL-2600 receiver is deployable today to fulfill critical infrastructure PNT objectives such as those outlined in Executive Order 13905 on the responsible use of PNT in the U.S. and the emerging mandates for a GNSS-independent backup solution in Europe,” said Said Jackson, president of JLT.

    The STL-2600 receiver is also useful in marine applications where GNSS signals are regularly denied or manipulated and for stationary high-accuracy timing applications such as 5G.

    The STL-2600 receiver can be directly connected to JLT’s GPS Transcoder products for glue-less retrofit capability of existing customer legacy GPS-only receiver systems to Galileo, GLONASS, BeiDou, QZSS and SBAS as well as adding the STL and optional atomic holdover capability to these legacy systems.

    The receiver module combines a custom-designed STL L1 LEO receiver and a latest-generation concurrent-GNSS receiver with a disciplined high-stability reference oscillator sub-system on one circuit board.


    Features and specifications of the STL-2600

    Form factor: 1.4″ x 2.0″ x 0.5″ (36mm x 51 mm x 13mm)

    Switching modes: User-selectable automatic and manual switching between GNSS and STL signal reception during jamming or manipulation events

    Integration: Incorporates into user systems just like a legacy GNSS receiver would using NMEA and SCPI serial messages, with the use of standard NMEA messages for STL positioning and timing features making system integration trivially easy

    Oscillator options and performance: Internal high-stability TXCO standard; capable of directly and gluelessly disciplining numerous optional DOCXO, CSAC and rubidium oscillators for holdover capability, with ultra-stable ADEV performance from 0.1s to infinity with better than 10E-12 stability when using a DOCXO or Rubidium as the holdover oscillator

    Low-power consumption: Ranges between 0.7 W to 1.45 W (depending on configuration) allowing for long-term battery operation for use cases without AC power

    Antenna support: One GNSS/STL combined standard; optional support of a second antenna for diversity

    Interfaces: TTL serial port standard; optional USB serial port allow easy evaluation and design-in

    Upgrades: One-button firmware updates performed in situ through any of the serial ports


    The receiver includes JLT’s proven frequency and timing disciplining and holdover IP deeply embedded into the entire signal chain for ultra-low phase noise performance and high-stability 1PPS and 10 MHz operation, even when using only the built-in TCXO oscillator.

    The unit operates fully autonomously from just a USB cable and is compatible with a customized version of the GPSCon software — offered at no cost to JLT customers — for monitoring and control.

    The STL signal has been deployed worldwide since 2016 and can be evaluated and implemented SWaP-C-effectively today via this receiver module.
