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

434
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

406
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...

    Area of Science:

    • Sports Science and Biomechanics
    • Athlete Performance Analysis
    • Data Analytics in Sports

    Background:

    • Sprints and accelerations are key performance indicators in sports.
    • Athlete-tracking technology, particularly Global Positioning System (GPS), is widely used to quantify these efforts.
    • Variations in data processing methods can lead to inconsistent reporting of high-intensity efforts.

    Purpose of the Study:

    • To investigate the influence of different Global Positioning System (GPS) data filtering techniques and settings on the detection of high-intensity efforts.
    • To assess how variations in velocity filtering, acceleration derivation, and minimum effort duration affect the reported number of sprints and accelerations.

    Main Methods:

    • Collected 10-Hz GPS velocity and acceleration data from professional soccer players.
    • Applied different velocity filters (median, exponential) and derived acceleration data using varying time intervals (0.2s, 0.3s) and filtering.
    • Identified high-speed running (≥4.17 m/s²), sprint (≥7.00 m/s²), and acceleration (≥2.78 m/s²) efforts using minimum durations (0.1-0.9s).

    Main Results:

    • Velocity filtering methods showed small to moderate differences in sprint and high-speed running detection, especially with shorter minimum durations (<0.5s).
    • Acceleration detection exhibited small to very large differences across methods, particularly when minimum duration was less than 0.7s.
    • An exponential decrease in the total number of detected efforts was observed as minimum duration increased, with acceleration efforts showing the most significant decline.

    Conclusions:

    • The choice of filtering techniques and minimum duration settings significantly alters the quantification of high-speed running, sprint, and acceleration efforts from GPS data.
    • Inconsistencies in data processing methodologies can substantially affect reported performance metrics.
    • Standardized and consistent data processing protocols are essential for reliable and comparable athlete performance analysis.
