ACCURACY ENHANCEMENT OF A LOW COST INS/GPS INTEGRATION SYSTEM FOR LAND APPLICATIONS

Publikováno v: Science and Technology Development Journal. 12:30-38

In this paper, the design of the low cost INS/GPS integration system is addressed with good accuracy. The Strapdown INS (SINS) and Cascade Kalman filter have been tested to ensure that the system can be operated flexibly between feed forward and feed

Publikováno v: Physica B: Condensed Matter. 327:378-381

Some effects of Co additive on the magnetic and electrochemical properties of the alloy series La 0.8 Nd 0.2 Ni 4.9− x Co x Si 0.1 ( x =0.1, 0.5, 0.75, 1 and 1.5) have been studied. The results of magnetic measurements indicate that the susceptibil

Preparation and magneto-caloric effect of La1−xAgxMnO3 (x=0.10–0.30) perovskite compounds

Autor: Nguyen The Hien, Nguyen Phu Thuy

Publikováno v: Physica B: Condensed Matter. 319:168-173

Polycrystalline La 1− x Ag x MnO 3 perovskite compounds (with x =0.10–0.30) have been synthesised by both the conventional solid-state reaction and the sol–gel method. While all samples with Ag concentrations up to 0.20 consist of single-phase

Narrow-range angle sensor based on wiggles in angular dependence of pseudo-Hall effect

Autor: Phan Le Kim, Nguyen Phu Thuy, Dinh Hung Manh, P. LeMinh

Publikováno v: Sensors and actuators. A: Physical, 97-98, 308-317. Elsevier

In this paper, for the first time a new type of narrow-range angle sensor based on pseudo-Hall effect is introduced and studied. This sensor is designed to be sensitive to very small changes in angle with detected range is scaled down to about 0.5°.

Land Vehicle Navigation System Enhanced by Vibration Analysis

Autor: Tran Duc Tan, Huynh Huu Tue, Luu Manh Ha, Nguyen Phu Thuy

Publikováno v: Journal of Research and Development on Information and Communication Technology.

Recent demand on the navigation systems is very high in many applications such as transportation and environment control. The inertial navigation system (INS) is not only suffering from errors caused by inertial sensors but also the vehicle dynamic.
