Shown here is an outdoor drone arena using IndoTraq’s Weatherproof HSKT™ Technology.
This close up shows the anchors inside a plastic enclosure mounted on a pole. The plastic enclosure is not required because the anchors are weatherproof, but the added enclosure provides protection for the 5V power supply.
The HSKT™ batteryless tag weighs 7.1 grams and can easily be added to a drone for autonomous flight.
