Expanding its footprint in precision timing, Microchip Technology Inc. (Nasdaq: MCHP) has unveiled a suite of GNSS Disciplined Oscillator (GNSSDO) modules. By merging its oscillator expertise with embedded atomic clock technology, the company is offering aerospace and defense customers ready-to-deploy Position, Navigation and Timing (PNT) solutions with improved resilience and flexibility.
The new GNSSDO modules are engineered to simplify the integration of highly accurate synchronization across mission-critical systems. Designed as plug-and-play solutions, the modules deliver assured PNT capabilities in applications where timing accuracy is central to performance, including secure communications, radar, guidance, navigation, and surveillance.
Unlike traditional GNSS receivers that are vulnerable to jamming or spoofing, Microchip’s GNSSDO modules combine Global Navigation Satellite System signals with advanced oscillator and atomic clock holdover capabilities. This ensures stable timing even in environments where satellite connectivity is intermittent or deliberately disrupted.
“Reliable timing is the backbone of modern aerospace and defense systems,” said Randy Brudzinski, Vice President of Microchip’s Frequency and Timing Systems business unit. “Our GNSSDO modules provide customers with an integrated, standards-based solution that reduces design complexity while ensuring the precision and resilience demanded in today’s operational environments.”
Microchip’s portfolio of GNSSDO modules leverages its heritage in timing and frequency control, spanning quartz oscillators, atomic clocks, and high-reliability system integration. The new family is available in a range of form factors and performance classes, giving developers flexibility to choose solutions that best fit platform requirements without the need for extensive customization.
Industry experts see demand for PNT resilience accelerating as defense programs seek alternatives to sole reliance on satellite-based timing. Governments worldwide are investing in backup and redundant PNT solutions amid concerns about growing electronic warfare and cyber threats. Microchip’s launch aligns with this push, offering ready-made building blocks for next-generation aerospace and defense platforms.
The company noted that the modules are designed to support long holdover durations, low phase noise, and robust frequency stability. Combined with its modular design, the portfolio enables seamless deployment across diverse environments, from airborne systems to ground-based infrastructure.
