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

350
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...

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...

Tapes are essential in surveying for accurate, durable, and short-distance measurements. Made from lightweight, nylon-coated steel, they offer flexibility and strength for rugged outdoor use. The nylon coating protects against rust and wear, extending the tape's life. Standard lengths, around 30 meters, are marked in meters and millimeters for precision.Surveyors select tapes based on site conditions and accuracy needs. Lightweight, nylon-coated tapes are commonly used for ease of handling and...

Area of Science:

  • Biomechanics
  • Indoor Positioning Systems
  • Sensor Fusion

Background:

  • Global Positioning System (GPS) is unreliable indoors.
  • Smartphone-based Pedestrian Dead Reckoning (PDR) systems face heading drift challenges.
  • Heading drift causes inaccurate indoor path estimation, leading to "wall-crossing" issues.

Purpose of the Study:

  • To develop an accurate 2D and 3D indoor pedestrian positioning system using smartphones.
  • To mitigate the heading drift problem in smartphone-based PDR.
  • To enable floor transition detection for enhanced indoor navigation.

Main Methods:

  • Implemented a 2D PDR system using pocket-worn smartphone inertial sensors.
  • Introduced a map-matching algorithm with a particle filter to correct heading drift.
  • Integrated smartphone barometer data to measure vertical displacement for 3D positioning.

Main Results:

  • The particle filter-based map-matching algorithm effectively prevented the "wall-crossing" problem.
  • Accuracy of indoor PDR was significantly improved.
  • Barometer fusion enabled calculation of vertical displacement and floor transition information.

Conclusions:

  • Smartphone-based PDR enhanced with map-matching and barometer data offers a viable solution for accurate indoor positioning.
  • This technology has substantial potential for indoor location-based services (LBS) despite sensor noise and movement complexities.
  • The system effectively addresses key challenges in indoor navigation, providing reliable positioning and floor detection.
