Errors in Global Positioning System01:26

Errors in Global Positioning System

245
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,...

Types of Global Positioning System Surveys

228
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

303
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,...

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

296
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...

Linear Approximation in Frequency Domain01:26

Linear Approximation in Frequency Domain

292
Linear systems are characterized by two main properties: superposition and homogeneity. Superposition allows the response to multiple inputs to be the sum of the responses to each individual input. Homogeneity ensures that scaling an input by a scalar results in the response being scaled by the same scalar.
In contrast, nonlinear systems do not inherently possess these properties. However, for small deviations around an operating point, a nonlinear system can often be approximated as linear....

Area of Science:

  • Geomatics Engineering
  • Satellite Navigation Systems
  • Robotics and Autonomous Systems

Background:

  • Global Navigation Satellite Systems (GNSS) are crucial for outdoor localization.
  • Real-Time Kinematic (RTK) offers accurate relative positioning but struggles with cycle slips, leading to low-accuracy float solutions.
  • Many applications require relative positioning rather than precise absolute coordinates.

Purpose of the Study:

  • To introduce a novel ambiguity-free relative GNSS tracking algorithm (Regtrack).
  • To improve the robustness and accuracy of relative positioning in outdoor environments.
  • To provide real-time, high-accuracy relative motion vector and baseline solutions.

Main Methods:

  • Developed the Relative GNSS Tracking Algorithm (Regtrack) for calculating relative baseline changes without ambiguity estimation.
  • Utilized a dead reckoning method for initial relative baseline solutions.
  • Implemented a parallel Extended Kalman Filter (EKF) for reinitiating the relative baseline upon validation failures.

Main Results:

  • Achieved millimeter-scale solutions for relative motion vectors between adjacent epochs.
  • Demonstrated sub-decimeter level relative baseline solutions, irrespective of base station static status.
  • Reported a tracking error of only 40 cm from ground truth after a 25-minute urban drive test.
  • Confirmed real-time performance with epoch calculation times under 80 ms (best results < 10 ms).

Conclusions:

  • The Regtrack algorithm provides a robust and accurate ambiguity-free tracking approach for outdoor applications.
  • The method significantly enhances relative positioning accuracy and reliability compared to traditional RTK under challenging conditions.
  • The real-time processing capability makes Regtrack suitable for dynamic and time-sensitive applications.
