DARPA created a chip for navigation without GPS

Of course, GPS is a great technology that allows you to navigate the terrain. But what to do when, for one reason or another, the signal from the satellites becomes unavailable? This will cause some inconvenience to the ordinary driver, but may also have disastrous consequences for military missions.

DARPA, an agency of advanced defense research projects, known for its high-tech projects , developed a microchip that allows navigation in the absence of a GPS signal.

The chip, called TIMU (“timing & inertial measurement unit”), is a set of 6 inertial measurement sensors (3 gyros and 3 accelerometers) as well as a high-precision clock generator (master clock). Such a set of devices provides all the necessary set of information sufficient to track movements from point A to point B during the time when the GPS signal is unavailable.
All this stuffing is packed into a tiny chip, with a volume of only 10 cubic millimeters:

This elegant design is made with the help of a new technological process, which allows you to create high-quality materials for multilayer packed inertial sensors and a clock generator - all this in a tiny package of 10 cubic millimeters. Each of the 6 microlayers of TIMU is only 50 microns thick, which roughly corresponds to the thickness of a human hair. Each layer has its own function, like a floor in a building.

It is not known whether this technology will ever go beyond military test sites, but I would like to see it in everyday household devices, such as, for example, smartphones.
