Tracking or searching for the existence of a human position in the forest or tourist attractions is an activity that is difficult for humans to do. Directional determination is necessary to reach the location of a destination. Because of an extensive area, many trees are tall, have human density, and have unknown paths. So that human visibility will be minimal. Based on this problem, a human tracking system is built in the forest using supporting devices from compass technology. It displays the user's directions and helps the user scan the Global Navigation Satellite System (GNSS) on device users with communication media components such as radio signals. The signal uses a Wearable Antenna, Arduino, Global Position System, Android Studio, and software applications to become a tracking tool that can provide location information. The user can view this location information through a smartphone with the application in real- time. So users can monitor their target location at all times quickly to save time, distance, and cost. The result and contribution of this location tracking tool research are that it can provide accurate location information. Besides, easy-to-use applications and hardware and software components can run well
