Agritech - Drones and Satellite

Drones and satellites are being used in Agritech to provide real-time data, making it easy for farmers to monitor and manage their fields effectively. The drone offers a bird's-eye view and provides real-time data to monitor crop health, apply fertilizers, and manage irrigation while satellites provide information about weather patterns, soil moisture, and crop conditions. It helps farmers in improving crop yield, at the same time reducing input costs.

Types of Agricultural Drones

• Fixed-Wing Drones: These drones are used for large-scale monitoring, designed for longer flights and cover larger areas.
• Multi-Rotor Drones: These drones are used for spraying pesticides, seeding, and targeted crop inspections. It provides better control and stability.
• Hybrid Drones: These drones use the benefits of both fixed-wing and multi-rotor drones i.e. longer flights and better stability.

Key Features of Agricultural Drones

• Sensors: Drones are equipped with cameras and sensors to get data of crop health, moisture, and plant stress.
• Real-Time Data Transmission: Drones are used to transmit real-time data to farmers, making it easy for them to take quick actions based on field conditions.
• Autonomous Flight Capabilities: Modern drones are pre-programmed over designated routes for autonomous flights reducing the need of manual operation.

Types of Satellites Used in Agritech

• Earth Observation Satellites: These satellites are used for monitoring large-scale agricultural areas by capturing Earth's surface images at various resolutions.
• Geostationary Satellites: These are used for providing constant data for weather monitoring and forecasting. It remains constant at one fixed position.
• Remote Sensing Satellites: These satellites gather information on soil, crops, and environmental conditions.

Types of Data Provided by Satellites

• Optical Imagery: These are high-resolution images to observe crop conditions, detect pests, or measure growth patterns.
• Radar Imagery: These images are helpful in cloudy or low-light conditions, for monitoring soil moisture.
• Thermal Imagery: It captures heat data from fields to monitor crop stress, water usage, and temperature variations.
• Multispectral and Hyperspectral Imagery: It uses light wavelengths to provide detailed information about crop health, nutrient levels, and the environment.

Applications of Drones & Satellites

• Field Mapping: Drones are used for creating detailed maps of the field helping farmers to analyze crop growth and resources needed.
• Crop Monitoring: Satellites provide insight into entire regions for efficient monitoring of crops across large areas. This helps farmers to identify the targeted regions that need attention.
• Crop Spraying and Pest Control: Drones are now used for spraying fertilizer, insecticides, and pesticides. It optimizes the use of fertilizer and pesticides as it sprays only to regions where it is required rather than the entire field.
• Planting: Drones are also used for planting seeds with accuracy having an even distance between adjacent seeds.
• Weather Forecasting: Satellites monitor weather patterns to provide accurate climate data which is critical for irrigation, planting schedules, and harvesting.
• Drought and Flood Detection: Satellites can detect extreme weather conditions like droughts or floods. It offers early warnings to minimize crop damage.

Limitations of Drones & Satellites

• Regulatory Challenges: Some countries have strict laws for using drones. It requires permission to operate drones. Countries that have drone regulations are Bhutan and Morocco.
• Data Security: Collecting data through drones raises privacy and security concerns.
• High Initial Costs: The cost of buying drones, sensors, and using satellite data can be high for small-scale farmers.
• Lack of Technical Knowledge: It requires proper training to use drones and technical knowledge to make use of satellite data.
