Introducing the GYPRO®4300: A Cutting-Edge MEMS Rate Gyroscope
The GYPRO®4300, developed by Tronics microsystems, is a tactical-grade MEMS rate gyroscope that merges a compact digital design with low size, weight, and power (SWaP) characteristics, ensuring exceptional stability and precision.
This gyroscope features a closed-loop system that provides a wide input measurement range of ±300 °/s, a bandwidth of 200 Hz, and a latency of just 1 ms, making it perfect for dynamic applications that require dependable navigation, positioning, and stabilization.
Thanks to its closed-loop design, the GYPRO4300 delivers outstanding linearity and stability, guaranteeing accurate readings even in demanding conditions.
Key Features of the GYPRO4300
The GYPRO4300 is equipped with a 24-bit digital SPI interface, simplifying integration into various platforms such as UAVs (unmanned aerial vehicles), UGVs (unmanned ground vehicles), and USVs (uncrewed surface vessels).
Encased in a hermetically sealed ceramic surface-mount device (SMD) package, this gyroscope is designed to endure harsh environments, boasting impressive vibration rejection and a Mean Time Between Failures (MTBF) that exceeds one million hours.
Available in three resonant frequency configurations, the GYPRO4300 minimizes mechanical cross-coupling, enhancing its performance in multi-axis applications. Its bias instability is rated at 0.4 °/h (typical) and 2 °/h (maximum), while the angular random walk is measured at 0.07 °/√h,providing users with highly stable and low-drift readings essential for accurate dead-reckoning.
Applications of the GYPRO4300
With factory calibration across temperature ranges and an integrated self-test feature, the GYPRO4300 complies with REACH and RoHS regulations and is not subject to dual-use export controls, making it suitable for a wide range of high-precision applications.
Advanced Air Mobility
This sensor excels in GNSS-assisted navigation for advanced air mobility, where its high vibration rejection and minimal thermal drift are crucial for precise positioning in UAVs and eVTOL platforms.
Oil, Gas, and Mining industries
In sectors such as oil, gas, mining, and transportation, the GYPRO4300’s high MTBF and compact design make it ideal for survey instruments, Measurement While drilling (MWD) modules, and directional drilling applications.
Land transportation Solutions
For land transportation, the GYPRO4300 offers low bias drift and stable positioning for unmanned ground vehicles, while its robust design supports GNSS-assisted navigation and track geometry measurement in railway applications.
Marine and Subsea Operations
In marine and subsea environments,this gyroscope is well-suited for ship motion control,underwater vehicle navigation,and dynamic positioning,providing high stability and low bias drift.
The GYPRO4300 is tailored for designers of unmanned vehicles and navigation systems who need compact, precise sensors that deliver reliable performance in extreme conditions.
As a low-SWaP digital choice to conventional fiber optic gyros, the GYPRO4300 showcases high stability and low drift, ensuring accurate attitude determination even in challenging environments.
Highlights of the GYPRO4300:
- Bias instability: 0.4 °/h (typical)
- Angular Random Walk: 0.07 °/√h
- Closed-loop design for superior vibration rejection
- 24-bit SPI interface, housed in a ceramic SMD package
- Three frequency configurations to minimize cross-coupling
Tronics launched the GYPRO4300 as part of its third-generation tactical-grade MEMS gyro series, with production commencing in October 2023. This model pairs seamlessly with Tronics’ AXO®300 closed-loop accelerometer series,facilitating the development of multi-axis tactical-grade IMUs and INS.
An evaluation board, along with Tronics’ software, is available to expedite product assessment, enabling designers to harness the advanced features of this gyroscope. The GYPRO4300 series also lays the groundwork for future models like the GYPRO®4050,which will focus on north-seeking and precision heading applications.
