The GPS-free navigation

The GPS-system is playing a vital role in everyday life. That system is required in many everyday applications. But in the military area, the GPS is even more important than people even imagine. The GPS-guided bombs allow the aircraft can close their target freely from any direction.

The recon satellite must only locate the target from any point of Earth. And then it must just deliver that point to the attack systems. And then the GPS-guided system will fly the aircraft to the target.

The GPS makes also possible to locate own ground troops very accurate. And then the attack plane can attack the enemy with pinpoint accuracy. And this is the reason why the GPS satellites are the primary targets for the ASAT (Anti-Satellite) weapons. And that is the reason why GPS-free navigation is under development.

One of the simplest versions of the GPS-free navigation that can operate without GPS is the inertial navigation system. If the inertial navigation systems are operating as series the autopilot can fly the aircraft by using quite complicated routes. If the aircraft can use pre-planned speed, altitude, and turning directions. The GPS that operates by using a series of waypoints can be useful. When the aircraft's speed is known the distance or the length of the vector that it travels is easy to calculate. When the aircraft is reaching the turning point, the system turns it by using the pre-ordered angle.

Smart weapons can use the inertial navigation system connected to TERCOM-navigation. Engineers created that system originally for cruise missiles. But it can use in regular aircraft and drones.

The TERCOM system uses the images for traveling to the target. The satellites or other recon systems would take the images of the route that the missile or aircraft should use. And then the system compares the images stored in its memory with the data that its camera and lidar scanners bring to the system.

The inertial and image homing systems can use to aim weapons in cases that the GPS is unable to operate. The system must just need photographs of the target. And then the weapon would deliver at the flight range. Then the imaging seeker locates the target and the system selects the right attack angle and other parameters that are made precisely to a certain type of target. The hardened target requires 90 degrees of the hit.

If the robot operates on another planet the GPS that records the movements is enough. In the case, that the robot will go to the place where it cannot drive through it must only retake the same movements that it made in the opposite order. This kind of system can use in deserts and other planets. But the GPS-free navigation is required also in robots that are working in everyday life.

If the navigation and communication between the robot and control center are jammed in the places like tunnels the robot car must not drive backward when that thing is happening. It must drive independently and safely to the area. Where it can reconnect itself to the network.

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft. Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things. In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion. If we th

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful. Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down. The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

"NASA’s OSIRIS-APEX spacecraft successfully completed its closest solar pass, protected by innovative engineering solutions and showing improvements in onboard instruments. Credit: NASA’s Goddard Space Flight Center/CI Lab" (ScitechDaily, Innovative Engineering Shields NASA’s OSIRIS-APEX During Close Encounter With the Sun) The OSIRIS-APEX probe travels close to the sun. The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts. The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
