GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

Geoid and Ellipsoid01:28

Geoid and Ellipsoid

84
The Earth's shape is best described as an ellipsoid, a slightly flattened sphere created by rotating an ellipse around its minor axis. This flattening results in the polar axis being about 21 kilometers shorter than the equatorial axis. In contrast, the geoid represents the Earth's gravitational shape and aligns with the mean sea level (MSL). The geoid is an irregular equipotential surface where gravity is perpendicular at every point. Variations in Earth's mass distribution cause geoid...

Introduction to Global Positioning System

112
The Global Positioning System (GPS) revolutionized positioning on Earth, providing precise location data through satellite ranging. The GPS system was developed in 1978 by the U.S. Department of Defense  for military use, and it became available for civilian applications in 1983, transforming fields including navigation, fleet management, and time synchronization for telecommunications systems.GPS consists of satellites in medium Earth orbit, about 20,200 kilometers above the surface,...

Errors in Global Positioning System

82
Global Positioning System (GPS) technology has revolutionized navigation and positioning, but its accuracy is often compromised by various errors. These errors, stemming from environmental, satellite, and receiver-related factors, require careful mitigation to ensure reliable performance across applications.Atmospheric ErrorsGPS signals travel through the Earth’s ionosphere and troposphere, introducing delays which affect accuracy. The ionosphere is strongly influenced by charged particles,...

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

152
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
  • Wireless Communication

Background:

  • Wireless Sensor Networks (WSNs) face challenges in energy efficiency due to the nature of geocasting.
  • Geocasting, a location-based routing protocol, requires efficient path construction to conserve limited battery capacity of sensor nodes.
  • Existing geocasting schemes like FERMA, FERMA-QL, and GEAR have limitations in energy consumption.

Purpose of the Study:

  • To propose an efficient grid-based geocasting scheme (GB-FERMA) for WSNs.
  • To leverage Fermat points for optimal relay node selection in a grid structure.
  • To enhance energy efficiency and prolong the operational lifetime of WSNs.

Main Methods:

  • Developed a grid-based geocasting scheme (GB-FERMA) utilizing the Fermat point theorem.
  • Identified specific nodes as Fermat points within a grid-based WSN.
  • Selected optimal relay nodes (gateways) in the grid structure for energy-aware forwarding.

Main Results:

  • GB-FERMA demonstrated significant energy savings compared to existing schemes.
  • With 0.25 J initial power, GB-FERMA consumed 53% less energy than FERMA-QL, 37% less than FERMA, and 23% less than GEAR.
  • With 0.5 J initial power, GB-FERMA consumed 77% less energy than FERMA-QL, 65% less than FERMA, and 43% less than GEAR.

Conclusions:

  • The proposed GB-FERMA scheme effectively reduces energy consumption in WSN geocasting.
  • GB-FERMA's energy-aware forwarding strategy prolongs the overall lifetime of wireless sensor networks.
  • Grid-based Fermat point utilization offers a promising approach for efficient WSN routing.
