One of the premier technological programs in the Air Force today is the Low Altitude Navigation and Targeting Infrared for Night (LANTIRN) system. This major program currently being fielded for our tactical forces represents advanced electronics technology not only in the weapon system itself but also in its sup-

We present a system to estimate the altitude and motion of an aerial vehicle using a stereo visual system. The system has been initially tested on a ground robot and the novelty lays on its application and robustness validation in an UAV, where vibrations and rapid environmental changes take place. The two main functionalities are height estimation and visual odometry. The system first detects ...

An extended Kalman filter is derived for estimating the relative position and attitude of a pair of uninhabited air vehicles, designated leader and follower. All leader states are assumed known, while the relative states are estimated using line-of-sight measurements between the vehicles along with angular rate and acceleration measurements of the follower. Noise is present on all measurements,...

Walking insects probably monitor leg movements to estimate how far they travel, whereas flying insects monitor optic flow.

It is obvious that in the 21st century electronic maps have the sophistication to replace paper. This happens even in aircraft avionics. A device called electronic flight bag (EFB) can display digital aeronautical charts and other necessary navigation data. This article briefly describes the EFB and its advantages and application in the Czech Air Force (CZAF). Digital aeronautical charts and na...

As air traffic continues to grow, the Global Navigation Satellite System (GNSS) plays an increasingly important role in enabling the air space to efficiently handle the increase load. In fact, it will be the primary and often the only system capable of supporting key capabilities for the future airspace. However, GNSS is vulnerable to radio frequency interference (RFI) and spoofing, so an alter...

Position of surface objects can be fixed in many ways. The most popular radionavigational systems, including satellite systems, make possible obtaining nearly continuous and very precise ship’s position. However, under the water application of radionavigational systems is impossible. Underwater navigation requires other tools and solutions then these encountered in surface and air navigation. I...

Safety culture is broadly recognized as important for Air Traffic Management and various studies have addressed its characterization and assessment. Nevertheless, relations between safety culture and formal and informal organizational structures and processes are yet not well understood. We aim to improve the understanding of these relations by agent-based organizational modeling and thus provi...

The goal of this work is to develop techniques and tools to enhance small-spacecraft in-orbit autonomy. The focus is on developing perception and control algorithms to enable autonomous proximity operations, and performing preliminary validation in a laboratory air-bearing testbed. To achieve this, we have developed cubesat engineering models equipped with a simple cold-gas propulsion system, o...
