The HPA Ag Spray Drone is an autonomous system designed for broad acre spraying. Whilst drones are associated with small tanks and slow application rates, our advanced thrust vectoring VTOL technology solved this by enabling fixed-wing spraying at 120 km/h (74 mph) with a 7 m (23 ft) boom, whilst
simultaneously being capable of fully automated, ultra fast VTOL refills.


The result is an overall, refill-included single-aircraft rate of 150 acres/hr at 2 gpa and 100 acres/hr at 4 gpa, delivering performances comparable to
SP sprayers, with the benefits of aerial application, all at a significantly lower cost.


The HPA Ag Spray Drone wings are designed with an ultra high aspect ratio, winglets and laminar flow sections, reducing wing tip vortices and trailing edge turbulence, which minimizes flow-induced drift.

With rapid automatic refills and a 12 gal spray tank, higher water volumes and higher GPA (4 gpa) can be used without compromising productivity or coverage, minimizing drift from movement and evaporation associated with fine droplets.


Available on-board sensors and centimetre-grade GPS lets us perform our own crop scouting, giving you a complete picture of crop health before spraying. Scouting data can then be directly fed into the flight planner, letting us precisely target problematic areas with centimetre precision, giving you true, actionable precision agriculture.

Complete with a dynamic power system, this water resistant machine that is battery operated can either be flown autonomously by pilot phone with obstacle avoidance or in manual by ARC. It is made out of a carbon fiber material to embrace harsh operating environments harnessed with sensory intelligence.

There are four macro-molecule atomizing spray disks that are able to respond to commands such as stop or resume within 1 second avoiding over spraying or misses. The droplet size can range from 285 to 500 microns from each spray disk, The machine harbors a hover, return to home and emergency landing software in case of emergencies.  


The intelligent liquid tank is accurate and reliable autonomously sensing chemical density, temperature and volume allowing the machine to adjust chemical output whilst spraying depending on speed of the flight without interrupting flight mode preventing environmental pollution and chemical over spray.

The machine also supports virtual fencing and no fly zone functions, improving air space safety meeting national security requirements. It has the ability to trace all records of the flight such as operator, flight information and maintenance records. 

The chemical refilling station distances operators from chemicals as as it is accurately calculated based on route planning siphoning the chemical into the machine 

The XMission provides the flight control system with centimeter level navigation for a fully autonomous flight in various control schemes to meet specific demands for different application.

Made out of a carbon fiber and magnesium aluminium alloy the XMission is light weight and ideal for portability. 

Landscapes can be mapped accordingly to their terrain with the XMission as it can adjust itself between a standard pattern, linear pattern and a grid pattern for multiple scenarios. Target fields, adjust flight and imaging parameters all can be selected from the A2 controller.

The multi-spectrum camera can aid with fast information collection and decision making allowing images available to collate a 1:500 HD map which can than be applied directly into the spray drone for autonomous operation.

The XCam can ensure that 3D imagery is taken following the terrain of the landscape being mapped for complex environments insuring that distortion or blurring at high speed operation is not an issue.


If abnormalities are found the Xmission will perform a supplemental shooting at a lower altitude acting as a microscope whilst other areas are processing.


The agricultural intelligence mode can achieve a 'spray only where needs to be' goal through being picked up via infrared sensing. 


This automatic spreading machine designed for granular fertilisers or pesticides and seeding aids in terrain following as well as obstacle avoidance and directional sensing.

The jet seeder is made out of the same carbon fiber materials as the spray drone embracing harsh operating environments. 


Featured with high speed, focused air flow, granules or seeds are propelled by jets of air into the soil. The jet seeder is compatible with the spray drones therefore can work autonomously off the same A2 controller.  

The jet seeder can effectively disperse granules on up to 12 acres of land per hour. There are 8 electronic ducted fans generating high speed air flow of up to 18m/s. This ensures the operation is not effected by environmental winds.

The embedded rolling feeder ensures that the granules or seed are placed exactly where they are meant to be due to the flight controls center meter accuracy.


The jet seeder supports granules of 1mm up to 10mm in size and the dosage volume output can be compensated for according to flight speed.   


HPA utilize multiple methods to complete ground spraying tasks including quick spray reels and backpack spray units. HPA have a flat bottomed boat that is a handy tool to eliminate aquatic weeds in shallow watered areas. 

Stacked, compact and tough, the UTV Quick Reel spray system running off 12V power will eradicate weeds in the most difficult to access terrain. The spray tank holding 400L allows the ground applicator to cover a wide range of ground operating with a remote control 100m stainless steel hose reel that is programmed to the unit.
