 The new technology can replace the GPS. 

The new quantum photonic chips that act based on Weak Value Amplification (WVA) technology can replace GPS. The problem with the GPS is that it sometimes loses its contact with satellites in tunnels and cases where it's jammed. 

If a drone operates over open ground-area. It can use DSMAC (Digital Scene-Matching Area Correlation). In that case, there is a satellite or aerial image of the route that the drone should follow on its computer. Then the system compiles those images with images, that the CCD camera takes. 

And if images match the drone is on the right route. In some cases the DSMAC uses Lidar but the problem is that especially in war zone things like houses can be destroyed and the land area might be turned different than it just were because of the use of fire. In cases where a drone must go to caves, it must use some other navigation tools than just GPS. The systems that replace the GPS must also be in cases where drones research things like Titan Moon or operate under the ice or highly radioactive areas.

The same systems that developers used in drones. Can operate in cell phones and nanomachines. The new photonic microchips or their nano-size successors can give nanomachines the ability to navigate in the human body without outside control. 

In those cases, the regular systems use gyroscopic navigation. But the problem with gyroscopes is moving parts and the size. The photonic microchip uses nano-lasers or photons. That is trapped between 100% reflecting mirrors. Those photonic microchips are more resistant to mechanical stress than gyroscopes. 

The idea is that in the quantum system select begin and end values that are not parallel. 

The new photonic chip measures how the kinetic energy interacts with trapped photons. And that thing can replace the gyroscopes. Those kinds of photonic microchips are smaller than gyroscopes. That means that those systems can also be in nanomachines. The nanomachines use similar networked, cloud-based data-processing architecture as bigger drones. 

But those small systems are smaller. There are a lot of expectations for that kind of system. But they require many new tools like new navigation systems. The nano-size robot drones can search the possible anomalies in machines and other systems. 

As I wrote earlier photonic microchips can give nanorobots the ability to navigate independently in the human body. And that thing is the new era for nanomachines and next-generation medicines. The small-size systems require small-size devices.
