چکیده

Increasing availability of mobile devices with GPS receiver gives users the possibility to record and share a variety of location-based data, including GPS tracks. We describe a complete real-time system for acquisition, storage, querying, retrieval and visualization of GPS tracks. The main problems faced are how to store the data, how to access and how to visualize large amount of data. We propose to reduce the quantity of the data to be visualized, without affecting visualization quality. In order to achieve this, our system uses a fast polygonal approximation algorithm for different map scales along with a bounding box solution.

Real-Time Interference Detection in Tracking Loop of GPS Receiver

Global Positioning System (GPS) spoofing could pose a major threat for GPS navigation ‎systems, so the GPS users have to gain a better understanding of the broader implications of ‎GPS.‎ In this paper, a plenary anti-spoofing approach based on correlation is proposed to distinguish spoofing effects. The suggested ‎method can be easily implemented in tracking loop of GPS receiver...

Applications of Mathematical Models of Road Cycling

This contribution discusses several use cases of mathematical models for road cycling. A mechanical model for the pedaling forces is the basis for an accurate indoor ergometer simulation of road cycling on real-world tracks. Together with a simple physiological model for the exertion of the athlete as a function of his/her accumulated power output, an optimal riding strategy for time trials on ...

A Real-Time GPS Civilian L1/L2 Software Receiver

A dual-frequency civilian GPS receiver has been developed that runs 10 tracking channels in real time using a software correlator. This work is part of an effort to develop a flexible receiver that can use the new GPS L2C CM/CL signals as they become available on L2 without the need for new correlator hardware. The receiver consists of an RF front end, a system of shift registers, a digital dat...

CrowdPath: A Framework for Next Generation Routing Services Using Volunteered Geographic Information

Our proposed system CrowdPath is based on the hypothesis that people know their commute area better than conventional routing services that use traditional digital roadmaps and shortest path algorithms. The knowledge and experiences of drivers reflected in volunteered commute routes may provide better routes. By leveraging such available volunteered geographic information (VGI), our goal is to ...

Advanced interferometric synthetic aperture radar (InSAR) time series analysis using interferograms of multipleorbit tracks: A case study on Miyakejima

[1] InSAR time series analysis is an effective tool for detecting spatially and temporally complicated volcanic deformation. To obtain details of such deformation, we developed an advanced InSAR time series analysis using interferograms of multiple-orbit tracks. Considering only right(or only left-) looking SAR observations, incidence directions for different orbit tracks are mostly included in...
