VIAVI Solutions Inc. (NASDAQ: VIAV) announced the launch of the µPNT GDO-1000, a GNSS-disciplined oscillator designed for precision timing applications in space and power-constrained systems.

The device measures 22mm x 42mm and weighs under 4 grams, built in the M.2 B-key form factor. The company positions the product for defense and airborne platforms, unmanned systems, data center cards and communications equipment where traditional timing modules may be too large or power-intensive.

The GDO-1000 features dual-frequency L1/L5 GNSS reception with microsecond-class 24-hour holdover capability. The device draws approximately half a watt and uses a MEMS-based oscillator rather than traditional quartz Oven Controlled Crystal Oscillators.

"Until now, customers needing reliable timing in compact systems have had to choose between two suboptimal options," said Doug Russell, Senior Vice President and General Manager, Aerospace & Defense at VIAVI. "CSACs are expensive and supply-constrained. Full-size OCXO-based timing solutions are too large and power-hungry for many modern platforms."

The oscillator includes AI and machine learning algorithms developed by Jackson Labs, which VIAVI acquired, to predict and compensate for oscillator behavior across environmental conditions. The device accepts external 1PPS input and provides multiple 1PPS and 10MHz outputs for system integration.

VIAVI will display the GDO-1000 at the 2026 Joint Navigation Conference from June 1-4 at the Northern Kentucky Convention Center. The product launch follows growing demand for compact precision timing solutions amid concerns about GNSS interference in defense applications.
