For many years, MEMS inertial technology has been known for its consumer and industrial grade performance. However, recent developments have proven that the capabilities of MEMS sensors go beyond these expectations, demonstrating tactical performance levels that can disrupt the market.
When users switch to high-performance MEMS sensors, they are often pleasantly surprised by the results. These sensors not only outperform their expectations but also displace fiber optics and other competing technologies. They have proven to perform exceptionally well in various environments.
MEMS technology has not reached its limits yet. It holds immense potential in terms of capabilities and performance, enabling the industry to overcome its challenges. Companies like Silicon Sensing are working to unlock the full potential of MEMS technology.
One of the significant advantages of MEMS inertial sensors is their robustness and reliability. Unlike other technologies, MEMS sensors have no moving parts, allowing them to maintain performance even in harsh environments. This, along with their smaller size, lighter weight, lower power consumption, and cost-effectiveness, makes MEMS a preferable choice.
Compared to other technologies like mechanical gyros, ring laser gyros (RLG), and fiber optic gyros (FOG), MEMS offers distinct advantages. Mechanical gyros require more maintenance and are not as robust as MEMS sensors. RLG provides precision performance but at a higher cost. FOG offers excellent performance but also comes with a higher price tag.
Thanks to continuous advancements, MEMS inertial sensors are now capable of meeting the stability and precision requirements of navigation-grade applications. They are becoming a viable and affordable option even for applications that demand tactical grade performance.
To achieve navigation grade performance, continuous improvements are being made in areas such as bias, drift, noise, scale factors, and angle random walk. The focus is on achieving significant stepwise improvement that will disrupt the market for higher-end technologies. Silicon Sensing and other companies are working towards reducing the cost, size, weight, and power consumption of navigation-grade inertial sensors.
The ultimate goal is to enable users to gyrocompass in intense and dynamic environments and provide aided navigation in GNSS-denied environments. MEMS sensors are capable of gyrocompassing without external aiding and being less susceptible to local interference. Achieving sub-one degree an hour for residual bias is crucial for gyro-compassing, while navigation-grade performance requires even lower levels of bias. Additionally, improving noise and scale factor are priorities.
With continuous advancements, MEMS inertial technology is poised to disrupt the market, providing high-performance sensors with reduced cost and improved capabilities. This technology has the potential to revolutionize various industries by offering reliable and precise inertial solutions.
