JIYI Flight Controllers, Radars and Spray Automation for Agriculture Drones in India
Bharat Skytech supplies genuine JIYI flight control systems, navigation equipment and spraying drone sensors across India. A spraying drone is only as good as its decisions.
The frame holds the payload, the motors lift it and the ground station connects the pilot. The flight controller determines how the aircraft maintains its line over uneven fields, manages routes, responds to obstacles, follows terrain and controls spraying operations. JIYI builds this critical control layer specifically for agriculture drones, combining flight control, route planning and spray automation with the navigation, sensing and metering hardware required for precision spraying.
For Indian operators working across terraced fields, around tree lines and near powerlines, reliable flight control and sensing can directly affect application quality, operational efficiency and aircraft safety.
Bharat Skytech supplies the JIYI range across India, including the K++ V2 and K-3A Pro flight controller kits, GPS modules, CAN hubs, flow meters, and obstacle avoidance and terrain-following radar systems. We stock these alongside Hobbywing motors and propellers, EFT drone frames and spare parts and SIYI ground stations, allowing flight control to be specified as part of a complete agriculture drone build.

About JIYI
JIYI is a Chinese manufacturer of flight control systems built specifically for agricultural and industrial unmanned aircraft. Where general-purpose autopilots come from the hobby and research world and are adapted to farm work, JIYI’s agriculture controllers are designed around the job from the start – route and boundary planning for field work, spray rate control tied to ground speed, terrain following over sloping land, and obstacle sensing for the tree lines, poles and wires that define a real Indian field boundary.
The practical consequence is integration rather than assembly. A JIYI agriculture flight control kit arrives as a system – controller, GPS module, power supply unit and status LED – configured to work together, with a defined path for adding radars, a flow meter and CAN-connected accessories. An operator or integrator is configuring a system rather than building an autopilot from parts and writing their own spray logic.
The second consequence is spray-aware control. On a general-purpose autopilot, the spray system is something you bolt on and control separately. On a JIYI agriculture controller, spray rate, flow monitoring and mission progress are part of the same system, which is what makes consistent per-acre application achievable.
The JIYI range at Bharat Skytech
Flight control systems
- JIYI K++ V2 Flight Controller Kit – the agriculture drone flight control kit, supplied with GPS, remote LED and PSU. The core system for a spraying platform, and the base that the radars, flow meter and CAN hub build onto.
- JIYI K-3A Pro Flight Controller Kit – JIYI’s agriculture flight controller kit, an alternative platform for spraying drone builds.
Navigation and connectivity
- JIYI GPS Module for K++ V2 – the navigation module, available separately as a replacement or spare. Worth stocking as a spare on any commercial fleet, since GPS modules are exposed and take impact damage in field operations.
- JIYI CAN Hub (12 Module) – the CAN bus expansion hub for K++ flight controllers, allowing multiple CAN accessories – radars, metering and peripherals – to be connected to one controller cleanly.
Obstacle sensing and terrain following
- JIYI Obstacle Avoidance Radar Front (UAV-R21-F) – forward-facing radar for detecting obstacles ahead of the aircraft during a spraying run.
- JIYI Obstacle Avoidance Radar Rear (UAV-R21-B) – rear-facing radar, covering the reverse leg of a spraying pattern where the pilot’s visual reference is weakest.
- JIYI Terrain Simulating Following Radar – terrain following radar that allows the aircraft to maintain a consistent height above ground over sloping, terraced or uneven land rather than a fixed altitude above the take-off point.
Spray metering
- JIYI Flow Meter and Flow Meter Sensor – measures actual liquid flow through the spray system, which allows the controller to regulate application rate and to alert the operator when the tank is empty or the flow has stopped.
Applications and Use Cases
Pesticide and plant protection spraying. The primary application. Route planning, boundary definition and flow-controlled application are what make per-acre spraying commercially repeatable rather than a matter of pilot skill on the day.
Spraying over sloping and terraced land. Terrain following radar keeps the aircraft at a consistent height above the crop as the ground rises and falls. Without it, a fixed-altitude mission over a slope either flies too high – wasting chemical to drift – or too low, with obvious consequences.
Operations near tree lines, poles and powerlines. Front and rear obstacle avoidance radar addresses the single largest cause of agriculture drone losses in Indian fields. Most incidents are not motor failures – they are contact with something the pilot did not see in time.
Fertiliser and granule spreading. The same flight control and navigation layer applies with a spreader unit in place of the liquid tank.
Fleet operations by drone service providers. Standardising a fleet on one flight control platform means one configuration process, one training path, one set of spares and consistent application quality across every pilot on the team.
Drone assembly and system integration. Integrators building agriculture platforms use JIYI because the spray logic, route planning and sensing integration are already solved, which shortens time to a working aircraft considerably.
Training organisations and RPTOs. Trainee pilots benefit from terrain following and obstacle sensing while they are learning, and institutions benefit from fewer damaged airframes.
Why Buy JIYI from Bharat Skytech
We stock the sensing range, not just the controllers. Most Indian sellers list the K++ and stop there. We carry the front and rear obstacle avoidance radars, the terrain following radar, the flow meter, the CAN hub and the GPS module as separate items. If you want to add terrain following to an existing K++ platform, we can supply the part.
We supply the whole aircraft. JIYI flight control sits alongside Hobbywing motors and propellers, EFT frames and spare parts, SIYI ground stations and camera payloads, and Evercell Make in India batteries and chargers. A complete agriculture drone can be specified and sourced from one supplier, with compatibility confirmed across the whole system rather than component by component.
Compatibility confirmed before you order. Radar and CAN accessory integration depends on your controller version and configuration. Tell us what you are running and we will confirm what will work before you buy.
Spares availability for fleets. GPS modules and CAN accessories are exposed components that take damage. We stock them individually so a damaged module does not ground an aircraft mid-season.
Genuine product supply with documentation. Flight control is the component where counterfeit hardware carries the highest consequence. A failed controller does not degrade performance – it loses the aircraft and whatever is underneath it. We supply through our regular sourcing channels with proper invoicing.
Technical support in India, in your time zone. Configuration, calibration and integration questions answered by people who have set these systems up on working aircraft.
GST invoicing and B2B terms. As a B2B supplier backed by Thakral Corporation, we issue proper tax invoices and offer volume pricing for integrators, service providers, institutions and training organisations.
Pan-India dispatch, including to the agricultural districts where spraying operators are based.
How to Choose the Right JIYI System
Step 1 – Start with the flight controller kit, not the accessories. The controller defines what you can add later. Order the complete kit – controller, GPS, PSU and LED – rather than assembling it from separate parts, unless you are replacing a specific damaged item on an existing aircraft.
Step 2 – Choose between the K++ V2 and the K-3A Pro. Both are agriculture flight control kits. The right choice depends on your airframe, your intended accessory set and whether you are matching an existing fleet. If you already run one platform across several aircraft, there is a strong case for staying consistent – one configuration process, one training path, one set of spares. If you are building fresh, tell us your airframe and mission profile and we will recommend.
Step 3 – Decide on terrain following by looking at your land. If your fields are flat, a fixed-altitude mission works and terrain following radar is an optional upgrade. If you spray over slopes, terraces, undulating land or crops of varying height, terrain following changes application quality substantially. This is the accessory that pays for itself fastest in hill and mixed terrain districts.
Step 4 – Decide on obstacle avoidance by looking at your field boundaries. Open fields with clear boundaries are lower risk. Fields bordered by tree lines, poles, powerlines or structures are where most losses happen. Front radar covers the forward leg of a spraying pattern. Rear radar covers the reverse leg, where the pilot’s visual reference is weakest and where a surprising share of incidents occur. For commercial operations in typical Indian field conditions, both are worth specifying.
Step 5 – Add the flow meter if you are spraying commercially. If you bill per acre or need to demonstrate consistent application, flow metering moves you from estimated application to measured application. It also tells you immediately when flow has stopped – a blocked nozzle or an empty tank – rather than after you have flown a pass with nothing coming out.
Step 6 – Add the CAN hub when you add accessories. If you are connecting multiple CAN accessories to one controller, the CAN hub keeps the wiring manageable and serviceable. On a build with radars and metering, plan for it from the start rather than retrofitting.
Step 7 – Specify flight control alongside propulsion and airframe. All-up weight, arm configuration and power budget interact with the flight control setup. Sizing the controller after the aircraft is built usually means compromises. Our guidance on choosing the right ESC for 10L, 16L and 20L agriculture drones covers the power side of the same decision.
Step 8 – Check regulatory requirements. Drone operations in India are governed by DGCA rules, and requirements around equipment, registration and pilot certification vary by aircraft category and mission type. Confirm the current position for your use case with DGCA or a certified RPTO.

Frequently Asked Questions
Does Bharat Skytech supply JIYI products in India?
Yes. We supply JIYI flight control systems and accessories across India, including the K++ V2 and K-3A Pro flight controller kits, GPS modules, CAN hubs, flow meters, and the front, rear and terrain following radar range, with GST invoicing.
What is the difference between JIYI and SIYI?
They are different companies making different things, and the similar names cause genuine confusion. JIYI makes flight control systems – the autopilot that flies the aircraft, plans the route and manages the spray. SIYI makes the pilot’s ground station equipment – the handheld remote controller, the video link and camera payloads. A complete agriculture drone typically uses both: a JIYI flight controller on the aircraft and a SIYI ground station in the pilot’s hands. We stock both.
What is the JIYI K++ V2 flight controller?
It is JIYI’s agriculture drone flight control system, supplied as a kit with GPS module, remote LED and power supply unit. It handles route planning, spray control and navigation for plant protection drones, and supports the addition of obstacle avoidance radar, terrain following radar and flow metering.
Which is better, the JIYI K++ V2 or the K-3A Pro?
Neither is simply better. Both are agriculture flight control kits and the right choice depends on your airframe, the accessory set you plan to add, and whether you are matching an existing fleet. Standardising across a fleet has real practical value in configuration, training and spares. Tell us what you are building and we will advise.
What does terrain following radar actually do?
It measures the height of the aircraft above the ground below it, rather than above the take-off point, and allows the controller to maintain a consistent spraying height as the terrain rises and falls. On sloping, terraced or uneven land this makes a significant difference to application uniformity, and it removes a category of low-flying accident on rising ground.
Do I need both the front and rear obstacle avoidance radars?
Not necessarily, but for commercial spraying in typical Indian field conditions both are worth having. A spraying pattern flies forward and backward along successive lines. Front radar covers the forward legs. Rear radar covers the reverse legs, where the pilot’s view of the aircraft’s direction of travel is weakest. If budget forces a choice, start with the front radar.
What does the JIYI flow meter do?
It measures actual liquid flow through the spray system. That allows the flight controller to regulate application rate against ground speed, and it alerts the operator when flow stops – an empty tank or a blocked line – rather than letting the aircraft complete a pass spraying nothing.
Do I need the CAN hub?
You need it when you are connecting multiple CAN accessories to one controller – for example radars plus metering. It keeps the wiring organised and serviceable. On a simple build with no CAN accessories, it is not required.
Can I add radars to a flight controller I already own?
In most cases yes, but it depends on your controller version and current configuration. Tell us what you are running and we will confirm compatibility before you order.
Can I use JIYI with an EFT frame, Hobbywing motors and a SIYI ground station?
How do I know I am buying genuine JIYI hardware?
Buy from a supplier who invoices the sale and supports it afterwards. Flight control is the component where counterfeit hardware carries the greatest risk, because a failure does not degrade performance gradually – it loses the aircraft. Bharat Skytech supplies through our regular sourcing channels with proper documentation.
