Introduction• Vector-borne diseases (VBD) are
human illnesses caused by parasites,
viruses, and bacteria that aretransmitted by vectors.
• Malaria, dengue, chikungunya, yellow
fever, plague and Zika.

Fig.1. Vector-Borne Pathogens• VBD causes more than 700.000 deaths every year.

• 80% of the world's population are at risk of one or more of them [1].
4Introduction
Primary aim of the project isearly detection and predictionof VBDs by using:• Remote Sensing• Geographical Information System• Artificial Intelligence5THE NEED• Climate directly impacts the transmission of VBDs

7Mission Objectives
Primary Objective-Near-real-time data for detecting VBDs
-Creating a risk map of VBD

Secondary Objective-Backup for heavy rainfall or dense cloud coverage.
-Demonstrating SAR within a 6U CubeSat
Fig.4. RAINCUBE Demonstration [2]Third Objective-Enhanced data processing and interpretation using AI-Gathering data despite spatial and temporal constraints.

Concept of Operations
Why are active and passive sensors separated?

• Observation of the Earth’s surface andatmosphere.
• Operates in dark conditions• Can penetrate clouds, generate 3D images• Global observations of the Earth and it’satmosphere• Requires less power• For identifying land cover, mappingvegetation, detecting atmospheric gases
