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.

Precision Ground Control Station (PGCS)
Leptron's Precision Ground Control Station is designed for military and law enforcement use. The rugged touch screen display resists liquids, dust, and debris. Brightness controls are adjustable for day and night operations. Plan autonomous flights by simply dropping waypoints they specify for altitude, orientation, and aircraft speed. The rugged tablet screen displays aircraft flight data and live video simultaneously. An integrated on-screen check list provides the pilot peace of mind that the aircraft is prepared for flight.

  • Fully autonomous or manual touch screen
    flight command
  • Customizable waypoints
  • Autonomous take-off and landing
  • Built-in flight data controller
  • Minimum and maximum altitude settings
  • Preset speed control – slow, cruise, dash
  • Ability to modify flight plan mid-flight
  • Thousands of touch waypoints
  • Multiple automatic landing plans
  • Flight Simulator

RDASS Precision Controller
The RDASS Precision Controller provides fine-tuned navigation command and preprogrammed switchology putting the pilot in complete control. The ergonomic design makes aircraft operation simple and reduces fatigue.

  • Additional Video Out
    The Leptron Additional Video HDMI Out will securely streams video and flight data information from the RDASS to any HDMI compatible monitor that is within operating range of the aircraft.

  • Additional Video Ethernet Out
    The Leptron Additional Video Ethernet Out securely stream video and flight data to remote viewing monitors. Simply log-in to control and configure live video streams from any location with web access and a standard web browsing application.

  • Navigation Lighting
    Leptron designed the aircraft navigation light ring to assist with maintaining visual orientation and position of the RDASS during both day and night operations. The pilot can select between strobe or steady illumination. The LEDs are bright and low power consuming.
