Compact, high-performing inertial sensors and systems showcased at ION GNSS+ 2025
At ION GNSS+, from the 8th – 12th September 2025 in Baltimore, MD, Silicon Sensing will exhibit a new generation of robust, compact MEMS-based inertial technology offering critical performance gains in vital areas such as bias instability and angle random walk.
The company’s latest silicon micro electro-mechanical systems (MEMS) technology is redefining inertial boundaries, providing inertial performance comparable to larger, heavier, and more expensive FOG-based products while maintaining the small size, low weight, and power efficiency associated with MEMS-based sensors and systems. Consequently, precise, sustained inertial measurement is now available for many applications where this has been problematic, including the latest ultra-compact platforms, those with minimal available power, and those that operate over prolonged periods and in the most extreme environments.
Products on display at ION GNSS+ this year, will include:
