Integrating GNSS Technology for Precision Timing Solutions
Aerospace and defense applications are increasingly relying on Position, Navigation, and Timing (PNT) technology to ensure mission-critical accuracy and reliability. However, incorporating PNT into designs often requires specialized knowledge. To streamline this process, Microchip Technology (Nasdaq: MCHP) has introduced a range of GNSS Disciplined Oscillator (GNSSDO) Modules that combine their advanced embedded atomic clock technologies with precision oscillator solutions.
The Functionality of GNSSDO Modules
The GNSSDO modules cleverly process reference signals from GNSS or alternative clock sources, allowing them to discipline on-board oscillators according to the reference signals. This capability guarantees precise timing, exceptional stability, and holdover performance tailored to meet specific application requirements. Their use spans vital military and defense sectors, including radar, satellite communications, and communication systems operating in GNSS-denied environments.
Versatility and Customization
Not only does a GNSSDO module function effectively as a PNT subsystem within a more extensive design, but it can also operate as a standalone system. Providing accurate timing is essential for any high-performance system. Microchip manufactures the local oscillators used in these modules, ensuring reliable products. Additionally, customers benefit from versatile components such as 32-bit microcontrollers and SmartFusion® 2 FPGAs.
Introducing Innovative GNSSDO Modules
Microchip’s newly launched GNSSDO modules provide tailored solutions to diverse application environments:
- The MD-013 ULTRA CLEAN module represents Microchip's top-tier offering, supporting multiple GNSS constellations like GPS, Galileo, BeiDou, and NavIC. Designed for high-performance, this module includes an exceptional OCXO, delivering ultra-low phase noise and remarkable short-term frequency stability. Its specifications indicate a phase noise performance of -119 dBc/Hz at a 1 Hz offset and a noise floor of -165 dBc/Hz. Users can generate various outputs, including 1 PPS TTL, 10 MHz sine wave, and square wave disciplines, configured to an embedded 72-channel single-band GNSS receiver that can upgrade for advanced applications.
- The MD-300 module is tailor-made for rugged environments, compactly designed with a size of 1.5 × 2.5 inches. It features an embedded MEMS OCXO or TCXO for low g-sensitivity, high shock, and vibration resistance. With its Size, Weight, and Power (SWaP) performance, it is ideal for platforms like drones and portable communications systems, providing high-performance output signals.
- For Low Earth Orbit (LEO) applications, the LM-010 PPS disciplined module offers precise timing coupled with the necessary radiation tolerance. This standard platform module generates both 1 PPS TTL and 10 MHz sinewave outputs, making it adaptable for various external references.
Enhancing User Experience
“Microchip’s knowledge in PNT systems supports our customers’ seamless integration of GNSSDO modules into their designs,” mentions Randy Brudzinski, corporate vice president of Microchip’s frequency and timing systems business unit. Their products are customizable to meet specific requirements through bespoke solutions or standard product adjustments, providing comprehensive end-to-end development solutions.
