Abstract

Smartphone-based Global Navigation Satellite System (GNSS) positioning provides an accessible solution for location tracking in small-scale fishing activities, particularly for recording and retrieving the locations of fisherman’s traps. However, the position generated by smartphone GNSS may fluctuate over time due to receiver characteristics, signal conditions, environmental effects, and the frequency of location updates. This study experimentally evaluates the stability of smartphone GNSS positions for fisherman’s trap tracking under different location update intervals. An Android-based tracking application was developed using React Native CLI and tested on a Xiaomi Redmi Note 12. Three location update intervals, namely 5, 10, and 30 seconds, were evaluated under controlled outdoor conditions. The collected data consisted of latitude, longitude, timestamp, and GNSS accuracy information, while reference coordinates were used to assess positional deviation. Position stability was evaluated using Haversine distance, Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), standard deviation, positional variance, and error distribution. The analysis was designed to determine how changes in update intervals affect the consistency and dispersion of smartphone-derived GNSS positions. The results are expected to identify the update interval that provides the most stable positioning performance for fisherman’s trap tracking while maintaining an appropriate temporal resolution for field operation. The findings can provide an empirical basis for configuring location update intervals in Android-based tracking applications for small-scale maritime activities.
