IMUs have been available for years, as part of the inertial guidance systems of everything from ships to spacecraft to missiles. However, by incorporating cheap MEMS sensors, instead of expensive ring-laser gyros, TRX and other OEMs are bringing down the price of location tracking for a variety of applications, from finding people to protecting important assets.

The ADIS16407 is hardly inexpensive, especially when compared to some of the more commercial IMUs, which are only slightly less accurate.

According to TRX, commercial grade IMUs won't cut it when lives are at stake. Also, the uniforms that firemen, hazmat and soliders will have this IMU sewn into are in the same ballpark of cost.

This is a great use of technology. I don't see a problem with cost when you can help to protect our brave men on the front lines.

What is the incremental cost of this new IMU technology on top of a supporting GPS? It would be interesting to see where else it could be used. As a 23 mm cube = 1 square inch, it sounds like it is still too large (or was there an error in the dimensions in the article) to incorporate into a mobile phone. How much might the pricing come down with high volume production? If affordable (and small enough), it would be a natural replacement for any GPS system to improve accuracy when out of range of the satellites.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
