Agriculture is a complex system science and the knowledge of it is consisting of much concepts and relationships. Examinations in connection with site-specific farming have been carried out by our institute since 1998. Precision farming is a way of agricultural production, which takes into account the in-field variability, a technology where the application-seeding, nutrient replacement, sprayi...

At the Advanced Photon Source (APS), the desire to combine sample handling, sample positioning or goniometer functionality into one piece of equipment has provided the impetus for the development of a precision six degree-of-freedom robot with approximately 2 μm dynamic positioning uncertainty. This specification is driven by the need for a positioning uncertainty that should be 10 to 20 percen...

High precision positioning technology for a kind of high speed maglev train with an electromagnetic suspension (EMS) system is studied. At first, the basic structure and functions of the position sensor are introduced and some key techniques to enhance the positioning precision are designed. Then, in order to further improve the positioning signal quality and the fault-tolerant ability of the s...

The Chinese Gaofen-3 (GF-3) mission was launched in August 2016, equipped with a full polarimetric synthetic aperture radar (SAR) sensor in the C-band, with a resolution of up to 1 m. The absolute positioning accuracy of GF-3 is of great importance, and in-orbit geometric calibration is a key technology for improving absolute positioning accuracy. Conventional geometric calibration is used to a...

A real-time positioning technology that can operate indoors and outside anywhere in the world, with sub-cm accuracy, and at low cost, is the ultimate goal for many researchers. GPS can achieve cmlevel kinematic positioning accuracy, but with some major constraints. First and foremost the use of GPS signals for indoor positioning poses very difficult challenges, due to the very weak signal level...

DV-Hop positioning algorithm based on distance vector routing and GPS location was put forward. The paper presents a localization algorithm for sensor networks based on mobile beacon localization in wireless sensor networks. Wireless sensor network localization accuracy depends on the density of beacon node. In this paper, using the Monte Carlo localization algorithm to solve the problem of nod...
