Types of Global Positioning System Surveys

163
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...

Errors in Global Positioning System

167
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,...

Introduction to Global Positioning System

207
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,...

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...

Electronic Distance Measuring Instruments

192
Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over...

Area of Science:

  • Wireless communication
  • Indoor positioning systems
  • Signal processing

Background:

  • Wi-Fi round-trip timing (RTT) is used for indoor positioning.
  • RTT faces reception instability and multipath fading in non-line-of-sight (NLOS) environments, causing errors.
  • Existing received signal strength indicator (RSSI) methods also struggle with accuracy in obstructed areas.

Purpose of the Study:

  • To propose a high-precision RTT-based indoor positioning system.
  • To improve distance prediction accuracy and reception rates for RTT signals.
  • To enable real-time, accurate indoor localization despite environmental challenges.

Main Methods:

  • Utilizing a Convolutional Neural Network (CNN)-based RTT compensation distance network (RCDN) for stable distance prediction.
  • Employing a Recurrent Neural Network (RNN)-based region proposal network (RPN) for real-time positioning.
  • Implementing a scanning step to enhance the reception rate of time-of-flight (TOF)-based RTT.
  • Applying division processing to corrected RTT distances within the RPN for location determination.

Main Results:

  • The RCDN improves the accuracy and learning rate of predicted distances.
  • The RPN enables real-time positioning using corrected RTT data.
  • The integrated system achieves high-precision indoor positioning by addressing RTT instability.
  • The proposed method effectively mitigates errors caused by multipath fading in NLOS conditions.

Conclusions:

  • The proposed RTT-based indoor positioning system with RCDN and RPN significantly enhances accuracy.
  • This approach offers a robust solution for reliable real-time indoor localization.
  • The method effectively overcomes the limitations of traditional RTT and RSSI-based systems in challenging environments.
