gnss-disciplined oscillator technical

"launch of the µPNT GDO-1000, a new GNSS-disciplined oscillator built..."

A GNSS-disciplined oscillator is a precise electronic clock that runs on its own but is regularly corrected by signals from global navigation satellite systems (like GPS) to keep time accurate. For investors, it matters because accurate, traceable timekeeping is critical in industries such as finance, telecom, and utilities for synchronized systems, regulatory timestamping, and low-latency trading; think of it as a wristwatch that self-adjusts using a satellite signal to avoid costly timing errors.

m.2 b-key form factor technical

"GNSS-disciplined oscillator built in the M.2 B-key form factor."

An M.2 B-key form factor is a small, standardized physical connector and slot used on modern laptops and circuit boards to add components such as solid‑state drives, cellular or Wi‑Fi modules. Think of it like a shaped plug that only fits compatible sockets: the B‑key determines which types of drives and interfaces will work. Investors care because this design affects product compatibility, upgrade options, manufacturing costs and component supply choices that influence device performance and margins.

micro-electro-mechanical systems (mems) oscillator technical

"The Micro-Electro-Mechanical Systems (MEMS) oscillator delivers better..."

A micro-electro-mechanical systems (MEMS) oscillator is a tiny mechanical device, no larger than a grain of sand, that vibrates at a steady rate to create precise timing or frequency signals—think of it as a miniature tuning fork used inside electronics. Investors care because these components affect product performance, power use and manufacturing cost across mobile devices, networking gear and sensors; improvements or shortages can influence revenue, margins and supply-chain risk for firms that use or make them.

oven controlled crystal oscillators (ocxos) technical

"than traditional quartz Oven Controlled Crystal Oscillators (OCXOs)..."

A temperature-stabilized electronic clock that keeps a device’s timing signal extremely steady by enclosing the oscillator in a small, heated chamber. Like a thermostat that prevents a clock from running fast or slow as the weather changes, an OCXO delivers very low timing drift and phase noise compared with ordinary oscillators. Investors care because OCXOs are critical components in telecom networks, satellite systems and precision instruments, so demand, cost and supply affect product performance, margins and revenue for vendors serving those markets.

allan deviation technical

"with sustained phase noise and Allan Deviation performance under vibration..."

A statistical measure that shows how the variability of a time series (like prices or rates) changes when you average observations over different time windows; it is the square-root form of Allan variance. Think of it like testing how shaky a camera image gets at different exposure lengths: short windows reveal fast jitter, long windows reveal slow drift. For investors, it helps distinguish fleeting noise from persistent trends, improving risk estimates, horizon choices and algorithm calibration.

1pps technical

"Accepts an external 1PPS input, allowing it to be disciplined by M-Code GPS..."

1pps means one percentage point, the simple difference between two percentage figures — for example, moving from 3% to 4% is a 1 percentage point change (1pps). Investors watch percentage-point moves in interest rates, profit margins, yield, or growth because even a single-point shift can noticeably change expected cash flows, risk and valuation; think of it as a single-step change in the slope of a hill that alters how steep the climb becomes.

m-code gps technical

"allowing it to be disciplined by M-Code GPS, alternative navigation sources..."

M-code GPS is a hardened, encrypted radio signal used by military receivers to get positioning and timing information that’s much harder to jam or spoof than civilian GPS signals. For investors, M-code matters because upgrading satellites, chips, receivers, and secure infrastructure to support it creates steady demand and contract opportunities for companies in defense hardware, navigation chips, and secure communications—similar to replacing shared road signs with a private, tamper-resistant lane.

• µPNT GDO-1000 is the smallest, lowest-power package for precision timing with microsecond-class 24-hour holdover from a MEMS-based oscillator
• Ultra-compact design – no larger than a postage stamp and weighing under 4 grams

CHANDLER, Ariz., June 1, 2026  /PRNewswire/ -- VIAVI Solutions Inc. (VIAVI) (NASDAQ: VIAV) has announced the launch of the µPNT GDO-1000, a new GNSS-disciplined oscillator built in the M.2 B-key form factor. Measuring just 22mm x 42mm, the size of a postage stamp, and weighing less than 4 grams, the GDO-1000 is designed for platforms requiring accurate timing in places where traditional timing modules do not fit or are too power-hungry, including defense and airborne platforms, unmanned systems, data center cards and communications equipment.

GNSS interference has become a persistent and ongoing operational concern. Dual-frequency L1/L5 reception is increasingly specified in defense and critical infrastructure procurements as a baseline requirement. Demand for compact, low-power precision timing continues to grow across multiple markets, especially as warfighters and unmanned platforms limit payload to stay agile, and customers who designed in chip-scale atomic clocks (CSACs) face cost and lead-time pressure.

The µPNT GDO-1000 addresses these challenges through a unique combination of capabilities:

• Dual-frequency L1/L5 GNSS reception with microsecond-class 24-hour holdover, enabling precise, resilient timing in compromised conditions
• The M.2 B-key form factor drops into modern compute platforms, time appliance cards and embedded systems without custom mechanical design, all while drawing approximately half a watt
• Patented AI and ML algorithms developed by the Jackson Labs team, now part of VIAVI, predict and compensate for oscillator behavior across environmental conditions
• The Micro-Electro-Mechanical Systems (MEMS) oscillator delivers better thermal stability across the full military temperature range than traditional quartz Oven Controlled Crystal Oscillators (OCXOs), with sustained phase noise and Allan Deviation performance under vibration and shock
• Accepts an external 1PPS input, allowing it to be disciplined by M-Code GPS, alternative navigation sources, or other external references without hardware modification
• Multiple 1PPS and low-phase-noise 10MHz coaxial inputs and outputs for system integration flexibility, despite its miniature size

"Until now, customers needing reliable timing in compact systems have had to choose between two suboptimal options. CSACs are expensive and supply-constrained. Full-size OCXO-based timing solutions are too large and power-hungry for many modern platforms," said Doug Russell, Senior Vice President and General Manager, Aerospace & Defense, VIAVI. "The GDO-1000 offers a new path that doesn't force customers to compromise. Its holdover performance approaches what customers expect from atomic-class clocks, in a module that fits on a standard M.2 slot and draws approximately half a watt."

The GDO-1000 will be on display at VIAVI Booth 407 at the 2026 Joint Navigation Conference from June 1-4 at the Northern Kentucky Convention Center. As part of the event technical program, Lisa Perdue and Nino De Falcis of VIAVI will speak about a New Cesium-Less ePRTC Solution to Provide Timing for Homeland Critical Infrastructure.
