<h1 class="wp-block-heading" id="h-pakistan-s-eo-1-and-eo-2-earth-observation-satellites">Pakistan’s EO-1 and EO-2 Earth-Observation Satellites</h1>



<p><strong>A Scientific but Easy-to-Understand Overview</strong> <strong>By Dr Shakir Ullah</strong></p>



<p>Pakistan Space agency has been steadily developing its space capability through Earth-observation satellites built under the supervision of Pakistan Space agency named as <strong>SUPARCO</strong>.<br>The <strong>EO-1</strong> and <strong>EO-2</strong> (The complete and easy introduction is below in the article) satellites are designed not for communication or broadcasting, but for <em><strong>scientifically studying the Earth</strong></em> to support<strong> agriculture, disaster management, environmental monitoring, and national planning.</strong></p>



<p>These satellites represent an important shift:<strong> from relying on foreign data to producing accurate national data independently.</strong></p>

<p>An Earth-observation satellite is a spacecraft that circles the planet and measures how sunlight interacts with<strong> land, water, vegetation, and atmosphere.</strong></p>

<p>Instead of “taking ordinary pictures,” it performs <strong>remote sensing</strong>, which means:</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow">
<p>Measuring reflected energy from Earth’s surface and converting it into scientific data.</p>
</blockquote>



<p>Every surface reflects light differently. By studying these differences, scientists can identify crops, soil condition, water levels, pollution, and land changes.</p>

<h2 class="wp-block-heading" id="h-scientific-working-principle">Scientific Working Principle</h2>



<p>EO-1 observes Earth using <strong>multispectral imaging</strong>, which means it measures several bands of light:</p>



<ul class="wp-block-list">
<li>Visible light (what human eyes see)</li>



<li>Near-infrared light (useful for vegetation analysis)</li>



<li>Reflected radiation from soil and water</li>
</ul>



<p>Different materials produce different spectral signatures:</p>



<figure class="wp-block-table"><table class="has-fixed-layout"><thead><tr><th>Surface Type</th><th>How It Reflects Light</th><th>What Scientists Learn</th></tr></thead><tbody><tr><td>Healthy vegetation</td><td>Strong infrared reflection</td><td>Crop health</td></tr><tr><td>Dry soil</td><td>Weak reflection</td><td>Drought detection</td></tr><tr><td>Water bodies</td><td>Absorb light</td><td>Flood mapping</td></tr><tr><td>Urban structures</td><td>Reflect heat differently</td><td>City expansion</td></tr></tbody></table></figure>



<p>So EO-1 converts light into measurable environmental intelligence.</p>
