    New Geodash intends to bring map-free, AI-driven precision spraying to industrial agriculture

    Joint venture between DroneDash and Geodnet targets oil palm, sugarcane and broad-acre operations across Southeast Asia, the United States and South America.

    DroneDash Technologies and Geonet are forming Geodash Aerosystems Pte. Ltd. — a Singapore-incorporated joint venture to develop a new class of agricultural spraying drone for large-scale, industrial farming operations. Commercial deployment is set for Q3 2026.

    Unlike conventional agriculture drones that require repeated manual pre-mapping before each deployment, Geodash Aerosystems’ platform uses real-time AI vision and centimeter-accurate RTK positioning to perceive, navigate, and adapt dynamically during flight. The result is faster deployment, lower operating costs, and continuous agronomic intelligence from the same system that does the spraying.

    Most agricultural spraying drones in operation were adapted from general-purpose UAV platforms. Before each deployment, operators must manually survey and map the field, generate static flight plans, and repeat the entire process whenever terrain, planting patterns, or canopy profiles change. In oil palm plantations and large-scale row-crop environments, this mapping overhead directly limits how many hectares a team can cover and how quickly they can respond to emerging crop conditions.

    The operational constraints are compounded the larger the estate. Manual pre-survey and field mapping is required before each deployment. Static flight plans must be recreated when terrain or canopy profiles change. Plans have limited adaptability to uneven terrain and mixed-age crops, when erosion or other changes occur.

    Geodash Aerosystems’ drone architecture removes pre-mapping from the deployment workflow entirely. Using DroneDash’s proprietary AI vision system, the aircraft performs real-time perception of plantation structure, canopy height, and terrain features during flight. Geodnet’s RTK correction network delivers centimeter-level positional accuracy throughout each mission.

    This combination enables:

    • deployment without pre-mapping or manual mission surveys
    • dynamic interpretation of rows, trees and operational zones
    • continuous altitude and spray-rate adjustment over variable terrain
    • rapid redeployment after replanting or field reconfiguration
    • tree-level and zone-specific variable-rate application.

    Situational awareness is generated dynamically during flight — not through a separate pre-deployment process. Each aircraft maintains geofencing controls, safety constraints, and full operational data logging for regulatory compliance and audit traceability.

    Agronomic Intelligence Layer

    Each GEODASH Aerosystems drone is integrated with DroneDash’s AI Smart Farming backend, which transforms every operational flight into a continuous data-collection activity. Spraying missions generate field data used to produce:

    • canopy density and uniformity analysis
    • crop stress and anomaly detection
    • zone-level health scoring
    • spray effectiveness validation
    • terrain and drainage profiling
    • historical trend analysis across blocks and seasons.

    Backend AI analytics then deliver actionable decision support to plantation managers and agronomy teams: early indicators of pest, disease, or nutrient stress; identification of underperforming zones; optimized spray timing and dosage; and data-informed planning for replanting and fertilization. The drone functions as a continuous aerial intelligence layer, not a standalone spraying machine.

    Geodash Aerosystems targets industrial agriculture markets where deployment speed, terrain adaptability, and precision matter most: oil palm plantations in Southeast Asia; sugarcane, soybean and corn operations in the United States; and palm, sugar and broad-acre estates in South America.

    Pilot deployments and system validation have been conducted throughout 2025 and into early 2026 in collaboration with plantation operators. Commercial deployment is targeted for Q3 2026, following completion of manufacturing readiness and regulatory approvals.

  • The rise of UAVs in agriculture, airports, more

    The rise of UAVs in agriculture, airports, more

    UAVs are finding places in the lives of more people than ever — farmers employing crop-spraying drones to counter a locust infestation in Pakistan, finding the way towards useful inspection tasks at an operating airport in the U.K., large airborne vehicles providing joy-rides around the U.S., and unfortunately showing up where they are not wanted so security staff have to use protection systems to deal with them.

    Crop Spraying

    New unmanned air vehicle (UAV) applications keep appearing. Once they do, they start to spread locally and even around the world. Crop management using UAVs has significantly progressed.

    The U.S. has used crop spraying to improve crop yield for many years, defending against insect infestation and plant diseases. GNSS guidance systems for crop-spraying aircraft was an early satnav equipment application that eventually became a standard for any fliers contacted by farmers to apply pesticides to protect their crops. Then companies began offering turn-key spraying, which was highly efficient and effective.

    UAVs are now entering this segment — they are capable of carrying higher capacity tanks, and autonomous/semi-autonomous navigation enables spraying with minimum supervision. This option is becoming more readily available to the farmer and costs less than using manned aircraft.

    Both Japan and China have used UAVs extensively for crop spraying; other countries turning to the solution are Africa, the U.S. and India. In China, more than a hundred different types of UAV are in use in agricultural applications.

    Farms around the mega-city of Karachi, Pakistan, have been infested by locusts, but the local government is short of the helicopters and ground applicators normally used for spraying pesticides. A recent graduate returning from his doctoral course in China brought with him knowledge of unmanned vehicle use in agriculture, and is urging rapid local adoption of UAV technologies to combat the locust infestation.

    Pakistani agriculture expert Shahzad Nahiyoon claims that UAVs are better suited to crop protection for small farms within difficult contours of the surrounding region. They are less expensive to operate than manned fixed-wing and rotary aircraft, may be operated locally from outside spray contamination zones, and can spray in confined areas. Equipped with a 20-liter tank, spraying one or two 20-meter-wide swaths, 6 to 10 hectares per hour can be treated.

    Drones at the airport

    Growing a little weary of drone incidents around airports, I was pleased to see a report I had overlooked from a year ago which indicated that trials at Manchester airport in UK had demonstrated airport and drone compatibility. This basically happened because an Air Traffic Control (ATC) system for unmanned aircraft or Unmanned Traffic Management (UTM) was shown to keep drones flying around the airport under full control while integrated with regular airport and drone operations.

    The trial — referred to as Operation Zenith — sponsored by the National Air Traffic Systems (NATS), made us of the GuardianUTM airspace management system, supplied by Altitude Angel, as the control system for eight trial drone missions at the airport. The drone UTM system was connected to the real-time Air Traffic Management (ATM) system which manages ground and air traffic at the airport, to ensure the control and safe separation of drones and aircraft. The UTM system also provided controllers with a real-time view of all operating drones.

    The trial demonstrated the efficient regulation of drone traffic within and around the extremely sensitive airport region. Everyone engaged in the trial made use of real-time electronic map displays driven by the UTM system, showing everything flying in and around the airport; aircraft and drones. Drone pilots used this information to ensure their operations remained safe while operating so close to commercial aircraft in the air and on the ground.

    NATS has now formed a strategic partnership with Altitude Angel to deliver this integrated UTM system at airports in the United Kingdom. The UTM system has successfully completed initial pilot trial and evaluation and now NATS intends to further demonstrate UAV management control at six U.K. airports later this year.

    Lift Aircraft unveiled its 18-rotor Hexa unmanned/manned aircraft more than a year ago — what’s new now is that 13,000 people have signed up to take one for a ride.

    The large drone weighs in at 432 pounds and can fly for 10-15 minutes with a single passenger.

    The Hexa is controlled by a single joystick, and an onboard iPad provides route guidance and manages take-off and landing. Classed as a powered ultralight air vehicle, it can be flown without a pilot’s license, so Lift announced that it will offer Hexa flights to anyone wanting to fly (in 25 selected U.S. cities) provided they physically fit into it and weigh less than 250 pounds.

    Lift intends to map each recreational flight area in 3D, and plug this map into the vehicle control system. The 13,000 people who signed up can expect to pay $125-250 for each joy ride. Lift has yet to announce the first location where the fun rides will take place.

    Counter-UAS system downs drones in Philippines

    The Southeast Asian Games were recently held in the Philippines with thousands of participants from eleven countries of Southeast Asia — the event was spread across 23 cities around the country. However, a number of uninvited drones showed up during the opening ceremonies on November 30th to take a look, but fortunately all were quickly dispatched.

    The DroneShield counter-UAS system had been deployed in advance for protection of the event, and the local security forces used the system to detect and disable the invaders. According to the company, security personnel found the drones using body worn RF detection devices, and the Dronegun was then used to disable them.

    Jamming the control link and GNSS L1 and L2 frequencies, UAVs are generally stopped in mid-flight when illuminated by the rifle-like device. DroneNode jammer in a suitcase was also used to provide blanket protection over a 1km circular area when the alarm was raised.

    In all, seven unauthorized drones were disabled, some of which were apparently flying near the intended flight path of the helicopter bringing President Rodrigo Duterte to the opening ceremony.

    Summary

    It might seem a little ridiculous that we’ve had to come up with systems to counter uninvited or malicious drones (C-UAS). Making provisions for protection is probably something most sensitive facilities will have to do. Its possible that governments may already be investing in such technology to protect many facilities. More drones available for useful, productive and even recreational applications means some can end up in the wrong hands.

    Nevertheless, good stuff comes out of drone applications, and the benefits seem to by far outweigh the need to protect ourselves against bad actors.
