Field Application of Global Positioning System

337
The Global Positioning System (GPS) has become an indispensable tool in fieldwork, offering unparalleled precision and efficiency for surveying, navigation, and infrastructure development. By harnessing signals from a constellation of satellites, GPS receivers determine the location of objects with remarkable speed and accuracy, often completing calculations within a second.Advantages of Modern GPS TechnologyContemporary GPS receivers are designed to meet the practical demands of field...

Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device

422
Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...

Area of Science:

  • Computer Science
  • Network Engineering
  • Robotics

Background:

  • Wireless sensor networks (WSNs) face challenges in achieving efficient area coverage with randomly distributed mobile nodes.
  • The Virtual Force Algorithm (VFA) is a primary approach for WSN area coverage but has limitations.

Purpose of the Study:

  • To improve the Virtual Force Algorithm (VFA) for homogeneous WSNs.
  • To address limitations of VFA, including convergence, boundary handling in the Region of Interest (ROI), effective force distance, and energy efficiency.

Main Methods:

  • An improved Virtual Force Algorithm (VFA) was developed.
  • An exponential function was introduced to define the virtual force relationship for rapid convergence.
  • Simulations were conducted to evaluate performance.

Main Results:

  • The enhanced VFA achieved a better coverage rate compared to the original VFA.
  • The improved algorithm reduced energy consumption related to node movement.
  • Faster convergence was observed with the modified VFA.

Conclusions:

  • The proposed improvements to VFA significantly enhance area coverage performance in WSNs.
  • The modified VFA offers a more energy-efficient and faster solution for mobile WSN deployment.
