This paper focuses on the design of an integrated navigation and guidance system for unmanned helicopters. The integrated navigation system comprises two systems: the Flight Path Planning System (FPPS) and the Flight Control System (FCS). The FPPS finds the shortest flight path by the A-Star (A*) algorithm in an adaptive manner for different flight conditions, and the FPPS can add a forbidden z...

With the continuous development of the industrialization process, the countries all over the world gradually appeared lack of agricultural labor force and aging phenomenon, which was especially prominent in developed countries. However the agricultural robot with high operating efficiency, high qualities of work will play an increasingly important role in future agricultural production. Robot n...

In the paper a prototype of a system for automatic landing of aircrafts and helicopters is proposed. The key requirement is to develop a completely autonomous system that does not depend on any kind of infrastructure or equipment, located outside the aircraft (like GPS, ILS, etc.). The idea is to control and navigate the aircraft using images, acquired by the camera, installed on the aircraft. ...

This article would study batch and recursive methods that used in terrain navigation systems. Terrain navigation has a lot ofdisadvantages and so researchers have been studied on different method of aided navigation for many years. Therefore, more types of aided navigation systems were introduced with advantages and disadvantages in terms of practical and theoretical. One of the main ideas for ...

Inertial navigation systems and gravimeters are now routinely used to map the regional gravitational quantities from an aircraft with mGal accuracy and a spatial resolution of a few kilometers. However, airborne gravimeter of this kind is limited by the inaccuracy of the inertial sensor performance, the integrated navigation technique and the kinematic acceleration determination. As the GPS tec...

Global Navigation Satellite Systems (GNSS), such as the Global Positioning System (GPS), have been widely utilized and their applications are becoming popular, not only in military or commercial applications, but also for everyday life. Although GPS measurements are the essential information for currently developed land vehicle navigation systems (LVNS), GPS signals are often unavailable or unr...

The safety and efficacy of minimally invasive surgery relies on visual information. We aimed to develop an integrated image navigation system (RoboSurgeon System) that combines head-mounted displays (HMDs) with multiple image modalities, and assessed its feasibility in 5 prostate cancer patients who underwent gasless single-port endoscopic radical prostatectomy. A robotically manipulated transr...

In this paper, the authors describe the integration of an INS and the Locata system, that uses Locata’s position, velocity and attitude solutions to calibrate INS observations in order to achieve an accurate, robust and continuous indoor navigation solution. The multi-sensor experiment conducted at Locata’s Numerella Test Facility is described in the paper. The measurement data were collected a...

In a GPS/IMU tightly-coupled navigation system, the extended Kalman filter (EKF) is widely used to estimate the navigation states, due to its simpler implementation and lower computational load. However, the EKF is a first order approximation to the nonlinear system. When the nonlinearity of the system is high, the negligibility in higher order terms of the nonlinear system will degrade the est...
