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

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

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...

Distance Measurements by Taping

Distance Measurements by Taping

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...

Background:

Global navigation satellite system (GNSS) and Global Positioning System (GPS) signals are frequently lost in challenging environments like urban canyons and tunnels.
Accurate pedestrian localization during these signal outages remains a significant technical challenge.

Purpose of the Study:

To propose and evaluate a novel location estimation method solely reliant on inertial measurements for pedestrian navigation.
To address the limitations of GPS-based localization in environments with signal obstruction.

Main Methods:

A deep network framework was developed for feature extraction and matching from inertial measurements.
Feature extraction and classification techniques were employed for mode partitioning.
Deep network models were analyzed and trained for different inertial measurement modes to derive localization information.

Main Results:

The proposed method demonstrated improved position estimation accuracy by utilizing appropriate deep networks tailored to different feature modes.
The approach effectively enhances pedestrian localization accuracy during GPS signal outages.

Conclusions:

Pedestrian localization using only inertial measurements is feasible and can achieve high accuracy.
Deep network models combined with feature mode matching offer a robust solution for navigation in GNSS-denied environments.
