FAQ
Detailed Overview
This comprehensive product demonstration shows why Marvelmind's ultrasonic indoor positioning system outperforms traditional laser distance meters and RTK GPS for indoor and challenging environments. The video features live testing over 103-meter distances using Horn ultrasonic beacons connected to Super-Beacon infrastructure. Key technical details include optimal transmitter beacon frequencies of 19kHz and 25kHz for reliable signal propagation. Unlike laser meters that require direct line-of-sight and clear atmospheric conditions, this indoor positioning system functions reliably in fog, dust, bright sunlight, through vegetation, and in underground/GNSS-denied areas. The setup explanation demonstrates proper Horn beacon installation and connectivity procedures. This indoor tracking system delivers the precision of laser measurement technology with the environmental flexibility required for autonomous indoor robot navigation, forklift tracking, drone operations, and warehouse automation. Organizations implementing advanced material handling systems benefit from this alternative to RTK GPS, which eliminates the cost and infrastructure complexity of satellite-based positioning while maintaining centimeter-level accuracy indoors.
