Abstract: Strapdown Inertial Navigation Systems (SINS) displays position errors which grow with time in an unbounded manner. This degradation is due to the errors in the initialization of the inertial measurement unit, and inertial sensor imperfections such as accelerometer biases and gyroscope drifts. Improvement to this unbounded growth in errors can be made by updating the inertial navigation system solutions periodically with external position fixes, velocity fixes, attitude fixes or any combination of these fixes. The increased accuracy is obtained through external measurements updating inertial navigation system using Kalman filter algorithm. It is the basic requirement that the inertial data and data from the external aids be combined in an optimal and efficient manner. In this paper an efficient method for integration of Strapdown Inertial Navigation System (SINS), Global Positioning System (GPS) is presented using a centralized linear Kalman filter.

Abstract: Program critical, high cost and delicate space hardware like satellite built with pressurized tanks, sensitive optics, delicate electronics and hazardous chemicals need protection from various environmental hazards during transportation. These environmental hazards include shock, vibration and handling loads and climatic hazards such as temperature, humidity, rain, dust due to harsh ambient atmospheric conditions etc. The Satellite Transportation System (STS) is equipped with adequate protection and monitoring system. The environmental data acquisition system is used to monitor the environmental conditions of satellite during transportation. This paper describes the data acquisition system used for quantitative validation of shock and vibration attenuation system and temperature and humidity control system. The acquired data are processed and interpreted to express the environmental conditions during various phases of development such as road survey analysis, performance validation and refinement of design for the shock and vibration isolation system of trucks and STS. Further, these data are used for the post-transportation health assessment of satellite that are vital to minimize post transportation tests on satellite.

Abstract: One of the major ecological and environmental problems confronting the Niger Delta region of Nigeria today is degradation and hazard arising from oil spill. Spillage occurs in this region either from vandalisation or sabotage by ethnic militants, youths who are jobless and therefore deliberately break open crude oil transport pipelines to scoop fuel for sale in the black market to earn a living or rupture of pipes due to ageing and mechanical malfunction. In most spillages, farmlands are lost, aquatic and wildlife is affected, and people are in many cases displaced from their homes. In extreme cases as occurred in Jesse, lives were lost. This paper examines the use of Geoinformation technology in oil spill response modelling and management. The use Global Positioning System (GPS) derived data for the creation of a management database is discussed. Data generated from the Jesse spill and fire site covering these areas were used to generate case study scenario for oil spill response modelling and clean up management operation.

Abstract: A GPS tracking system utilizing the license-free RF communication is proposed as viable alternative to using the available GSM network for low-cost maintenance. The proposed system is designed based on the popular 8-bit embedded system. It consists of a monitoring unit and a remote unit. Each unit is equipped with, among others, a GPS receiver and an RF transceiver as main components. While there is a need for the remote unit to be small and compact, the monitoring unit is also designed as a portable device. Prototypes are built for design verification. Initial functionality test shows that the system is capable of tracking mobile object not only in outdoor but also in indoor environment.

Abstract: The paper presents an extensive theoretical background related to the travel time and the studies that were conducted during the recent years on the subject. As a concept, travel time is related to the period of time spent in travelling between two different points in space. The analysis focuses on several aspects related to the travel time concept such as its usefulness, its influencing factors, and data collection methods for its determination. In order to also provide a practical outcome, the main interurban road connection between Cluj-Napoca and Tîrgu-Mureş was studied. The road trespasses both urban and rural localities in the North-Western of Romania. For the data collection process, a GPS-based equipment was placed on a test vehicle to run the route for multiple times, at different days and hours. The collected data were studied by means of statistical analysis in order to establish the most relevant aspects of the travel time. The research goal of the paper was to evaluate the influence exerted by demographics and type of locality on travel time by means of eventual delays. The main findings were employed to analyze the traffic conditions as well as the parameters that have a major impact on them. According to the results of the analysis, the traffic flow on the interurban route is best described by the travel time and consequently the delays registered due to multiple obstructive elements such as railway level crossings, pedestrian crossings within the localities, and level intersections between different roads category. However, according to the study, it can also be concluded that travel time and therefore the eventual delays are not influenced to a great extent by neither the type of transited localities - urban or rural, nor the demographics.

Abstract: In order to improve the information management of the modern digital agriculture, combined several modern digital agriculture technologies, namely wireless sensor network (WSN), global positioning system (GPS), geographic information system (GIS) and general packet radio service (GPRS), and applied them to the information collection and intelligent control process of the modern digital agriculture. Combining the advantage of the local multi-channel information collection and the low-power wireless transmission of WSN, the stable and low cost long-distance communication and data transmission ability of GPRS, the high-precision positioning technology of the DGPS positioning and the large-scale field information layer-management technology of GIS, such a hybrid technology combination is applied to the large-scale field information and intelligent management. In this study, wireless sensor network routing nodes are disposed in the sub-area of field. These nodes have GPS receiver modules and the electric control mechanism, and are relative positioned by GPS. They can real-time monitor the field information and control the equipment for the field application. When the GPS position information and other collected field information are measured, the information can be remotely transmitted to PC by GPRS. Then PC can upload the information to the GIS management software. All the field information can be classified into different layers in GIS and shown on the GIS map based on their GPS position. Moreover, we have developed remote control software based on GIS. It can send the control commands through GPRS to the nodes which have control modules; and then we can real-time manage and control the field application. In conclusion, the unattended automatic wireless intelligent technology for the field information collection and control can effectively utilize hardware resources, improve the field information intelligent management and reduce the information and intelligent cost.
