Example Use Case: Collision Avoidance and Safety in an Automotive Factory
In an automotive factory, workers and machines are equipped with UWB tags. These tags track locations with millimeter precision, minimizing the risk of collisions between workers and machinery or forklifts. When workers approach hazardous areas, the UWB system automatically issues a warning and activates the relevant safety protocols, ensuring both employee safety and minimizing disruptions in production.
UWB is a superior solution for areas requiring precision positioning, providing real-time and highly accurate tracking across industries such as manufacturing, healthcare, and logistics.
GPS (Global Positioning System)
GPS (Global Positioning System) is one of the most effective technologies for location tracking over wide areas. Operated via satellites, GPS provides position, speed, and direction information, making it the most reliable and widely used solution in open spaces, especially for applications in logistics, agriculture, and transportation. However, GPS signals can weaken or be blocked indoors, so it’s often used alongside other RTLS solutions in closed spaces.
Technical Features of GPS
- Accuracy (5-10 meters): GPS can provide approximately 5-10 meters of accuracy in open areas, with high precision in unconfined terrains. However, accuracy may decrease in areas with dense buildings or signal blockage.
- Speed and Direction Information: GPS offers not only location but also movement direction and speed, making it valuable in sectors like logistics and transportation where tracking moving assets is essential.
- Wide Coverage Area: GPS has extensive global coverage, ensuring seamless operation even in international logistics operations. The global satellite coverage makes GPS a reliable solution for cross-city and cross-country transportation.
- Low Power Consumption: GPS devices only consume energy while collecting data. This low power usage is ideal for long-term use in vehicles and portable devices, though external power sources may be required for continuous updates.
GPS Use Cases
- Logistics and Transportation: GPS tracks trucks, trailers, and other vehicles, optimizing the shipping process and monitoring delivery times.
- Agriculture: Agricultural machinery equipped with GPS can perform precision agriculture over large areas, facilitating efficient management of planting, irrigation, and harvesting.
Example Use Case: Vehicle Speed Tracking and Safety Management in Open Areas
In a large mining or industrial site, vehicles equipped with GPS are tracked in real-time to monitor speeds. Safety and efficiency require vehicles to stay below specific speed limits, so GPS constantly transmits speed and location data to the system. When vehicles exceed the speed limit, an automatic alert is triggered, notifying security personnel.
GPS’s speed tracking and safety management features provide an efficient solution for large businesses operating in expansive areas, enhancing security and reducing accidents. Additionally, monitoring speeds can optimize fuel consumption, contributing to lower operational costs.
