When we talk about GPS satellites, what most people think about is how users use GPS positioning in a vehicle to navigate from one location to another. Many people are relying more and more on GPS, and driving basically depends on maps and GPS. If the interruption of GPS service will make people find no way for ordinary consumer users, then the GPS interruption is a disaster for the military, so a supplementary solution that can replace GPS equipment is needed.
Many different types of weapons used by the military rely on GPS signals to accurately guide and destroy enemy targets. If the GPS satellite system is out of service due to malfunctions or military strikes, then GPS missiles and bombs will fail. DARPA (U.S. Department of Defense Advanced Research Projects Agency) is also unable to resist the destruction of unprotected satellites in orbit that render military weapons ineffective.
So DARPA researchers are developing a thing called TIMU, the full name of Timing and InerTIal Measurement Unit (TIming and InerTIal Measurement Unit), this small chip can navigate around the world without relying on GPS satellites. This sensing device has a 6-axis inertial measurement unit, including 3 accelerators and 3 gyroscopes, and there is a high-precision master clock in this space of only 10mm.
DARPA said that using this chip allows the hardware to do relatively precise positioning. It can provide three key pieces of information that accurately guide to the target location, namely direction, acceleration and time. The chip is designed with 6 layers of silicon dioxide and has a thickness of 50 microns, which is only equivalent to the thickness of a hair. In addition, TIMU can also be used in non-military areas to provide indoor positioning for civilian GPS devices and those places that cannot be covered by GPS satellites.
