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

430
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...

Types of Global Positioning System Surveys

399
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...

Introduction to Global Positioning System

639
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

374
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,...

Buoyancy and Stability for Submerged and Floating Bodies01:11

Buoyancy and Stability for Submerged and Floating Bodies

3.3K
In fluid mechanics, buoyancy and stability are key concepts for understanding the behavior of submerged and floating bodies. When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body known as the buoyant force. This force acts vertically upward through a point called the center of buoyancy, which is the center of the displaced fluid volume. According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid...

Area of Science:

  • Computer Science
  • Electrical Engineering
  • Ubiquitous Computing

Background:

  • Internet of Things (IoT) drives indoor navigation research.
  • Existing systems require extensive site surveys, increasing deployment time and cost.
  • Lack of systems adaptable to dynamic environments like shopping malls.

Purpose of the Study:

  • Introduce Canoe, an indoor navigation system for shopping malls.
  • Eliminate the need for prior knowledge like floor plans or access point configurations.
  • Enable navigation using only readily available Received Signal Strength (RSS) data.

Main Methods:

  • Canoe utilizes RSS values published by shop owners at entrances.
  • Consumer and shop locations are estimated via maximum likelihood estimation.
  • Navigation directions are computed by comparing observed RSS values and target shop locations.

Main Results:

  • Extensive simulations and real-world experiments were conducted.
  • Canoe achieved precise navigation within 30 seconds with an error rate below 9%.
  • Effective navigation was demonstrated even when only 50% of shops published RSS values.

Conclusions:

  • Canoe offers an efficient, low-overhead indoor navigation solution for shopping malls.
  • The system's reliance on published RSS values simplifies deployment and maintenance.
  • Demonstrates the feasibility of crowd-sourced data for effective indoor positioning.
