4.1.1 High Precision Positioning

One of the most significant advantages of Compact Multi - System RTK Antennas is their ability to provide high - precision positioning. By receiving signals from multiple GNSS constellations, they can achieve centimeter - level accuracy in real - time. This is far superior to traditional single - system GPS antennas, which typically offer only meter - level accuracy. In applications such as surveying, where precise measurements are crucial, this high precision can save time and resources by reducing the need for repeated measurements.

4.1.2 Compact Size and Easy Integration

The compact size of these antennas makes them highly suitable for integration into a wide range of devices. In drones, for example, the small size of the antenna helps to reduce the overall weight and aerodynamic drag, improving the flight performance.
