The paper describes the development of a new integrated sensing system that provides real-time, georeferenced subsurface information for enhancing mining equipment operation. The system incorporates subsurface radar sensing, pose estimation, embedded computing, custom processing algorithms, wireless Ethernet, and advanced 3D visualization to provide a unique real-time sensing capability. Details on...
This paper presents a cost-effective approach to design an embedded autopilot system for a 4-rotor aerial vehicle. The system is targeted for autonomous control research, and it consists of an onboard system and a ground station. The onboard system interfaces with the vehicle and provides data link for sensor measurements and control data. The ground station provides a user-friendly interface for...
Quantification of exposure to psychosocial stressors and drug availability might assist in the prevention and treatment of substance-use problems. The core of such interventions lies in combining real-time self-report data (via Ecological Momentary Assessment, EMA) with real-time geolocation data (via GPS logging). Combining these types of data and linking the result with patients' clinical research...
This paper presents an intelligent on-line route guide system using leader-following concept in a fleet. In order to achieve the concept of a car leader leading other car members in a fleet, we establish their contact through the real-time GPS position data with a 3G wireless communication. Every car members can obtain the real-time positions of the leader car and other car members. Then, the corresponding...
In this paper we present the design and implementation of a telematic network to provide real-time location based services for tactical units which interconnects soldiers, weapons systems, fire control units, sensors, reconnaissance and surveillance radars, as well as unmanned aerial vehicles, with company-level command and control centers to the national center at the command level and the Defense...
The key technology of the fatigue reliability design and test evaluation of freight train is to establish freight train load spectrum based on operating conditions. Design a set of remote monitoring and control system for the establishment of loading spectrum's actual needs. The system uses GPS technology for vehicle location, speed and other information, through the GPRS technology to build car-side...
This paper elaborates on the Cybercars-2 Wireless Communication Framework for driverless city vehicles, which is used for Vehicle-to-Vehicle and Vehicle-to-Infrastructure communication. The developed framework improves the safety and efficiency of driverless city vehicles. Furthermore, this paper also elaborates on the vehicle control software architecture. On-road tests of both the communication...
In order to meet the need to POS for high accuracy real-time motion imaging in the high resolution earth observation system, an integrated navigation computer based on FPGA and DSP was designed. FPGA independently accomplished the synchronous sampling of GPS data and IMU multichannel pulse signals; the bidirectional communication between DSP and FPGA was in the interrupt mode by EMIF; the navigation...
In Power SCADA system, real-time database is regarded as the kernel of the whole architecture. Based on the features of current main products in this field, the paper prompt a new structure with setting up a real-time database on each network node and provide a communication mechanism for all databases synchronization, then appraise this new structure by comparing with other main products designs.
The paper deals with the real-time monitoring of the European Geostationary Navigation Overlay Service (EGNOS). Possible approaches to the monitoring are discussed at first. The rest of the paper presents the development of C++ software for real-time monitoring of EGNOS performance in the position domain. The software is intended to be used within the GNSS monitoring station run by the Department...
In this paper we present a software platform dedicated to the maneuverability assessment of naval units, both on surface and submerged. The suggested platform exhibits such characteristics as real-time processing of ship track and heading data, off-line processing of post-processed DGPS data for increased accuracy and real-time calculation and graphical presentation of maneuvering performance evaluation...
The tropospheric zenith delay of Great Wall station in Antarctic grouped with surrounding IGS stations is solved by GAMIT/GLOBK software using GPS observational data. In the process of solving, IGS final ephemeris and precision forecast ephemeris are used to solve the zenith delay in the software. The solutions are analyzed to draw some conclusions. The results show that the zenith delay of different...
Based on the background that vehicle monitoring system had urgent necessity recently, the paper put forward a overall scheme of vehicle monitoring system combining with global positioning system (GPS), global system for mobile communication (GSM) and geographical information system (GIS), introduced the key technologies of this monitoring center software, designed the function software of monitoring...
Inertial navigation generally involves inertial based acceleration and rotation rate, and GPS position and velocity measurements of a platform. Software algorithms are used to convert the readings to meaningful navigational information. A feasibility study was done on the implementation of an inertial navigation system on a single board computer operating under a open source real-time Linux distribution...
A real time network is introduced to the development of a test system of SINS/GPS (ship's inertial navigation system/Global Position System) integrated navigation system. Because only the three-axis angular motions can but the three-axis linear motions can't be emulated by three-axis revolving table, the complete navigation computing is accomplished by external compensation of linear motions. A navigation...
In this paper, a novel design of refining precision of pseudo-range is presented and ameliorates the pseudo-range degradation in a scheme of reducing local code replicas' adjustment for real time software GPS receiver. The code phase error corresponding to pseudo-range degradation is estimated and compensated by linear interpolation and curve fitting, according to the discriminator output in delay...
This paper describes how to carry out functions of RFID device, how to enhance RFID technology, and how to use Wi-Fi technology to follow real-time tracks so as to definite location. Also, this paper lists some produce newly developed using 802.11 technology. And after being inspired from this technology, we propose some ideas, which would be helpful to RFID technology in future.
