Leptron RDASS™ Precision
Unmanned Quadcopter

The Rapidly Deployed Aerial Surveillance System (RDASS) Precision by Leptron UAS, Inc. is a vertical takeoff and landing multirotor platform used for stability, versatility and professional-grade remote sensing. The RDASS Precision model offers the same aerodynamic aircraft design as the RDASS HD, but it integrates a military-grade autopilot system with precision GPS and an advanced inertial navigation system. The RDASS is commanded from Leptron's Precision Ground Control Station (PGCS) that supports autonomous flight operations with the option of taking direct control at any time. The PGCS also offers the pilot superior situational awareness by displaying aircraft position on a moving map and real-time video from the aircraft's camera(s).

The RDASS camera mounting system accepts Leptron stabilized or fixed gimbal configurations. Each gimbal is perfectly balanced to minimize power consumption to optimize in-air performance. Additionally, the RDASS Precision can be equipped with navigation LEDs, red and blue strobe lights, and additional video viewing stations. With dozens of user defined system configurations available, the RDASS Precision is an ideal choice for public agencies and sensitive sites.

See what the RDASS™ can do

RDASS™ Overview:   The Leptron RDASS™ offers simplicity with a single case for the helicopter drone, video, spare batteries and charger. The system offers stunning HD video and the video is from an RDASS taking video of both an Avenger and an RDASS in the air.

Leptron Utility Flights:  The Leptron RDASS™ and Avenger™ are used to inspect utility lines. The systems offer both HD video and infrared camera systems. In addition, live view camera views allow ground personnel the ability to safely view potentially dangerous insulators and high tension power equipment.

RDASS™ Industrial Use:  The Leptron RDASS™ is used for industrial safety inspections, quarry blasting and topographic mapping. The system utilizes a full autopilot in high winds and extreme conditions with a live HD camera view.

RDASS™ Law Enforcement:   The Leptron RDASS™ offers simplicity and portability for law enforcement. The system can be hand launched or landed. The system offers up close views and the ability to offer views for SWAT, accident scene reconstruction, search and rescue among many.
