Types of Air Satellites
Understanding the different types of air satellites is essential to grasp how they are deployed and their roles in monitoring the atmosphere. Each category of satellite operates on unique principles that enable them to serve specific purposes. The classification into Low Earth Orbit (LEO), Geostationary, and Polar Orbit satellites is primarily based on their operational altitudes and the geometric characteristics of their orbits.
These distinctions impact their coverage area, data collection capabilities, and operational latency.
Low Earth Orbit (LEO) Satellites
Low Earth Orbit satellites are positioned at altitudes typically ranging from 160 kilometers to 2,000 kilometers above the Earth's surface. This proximity allows for high-resolution imaging and real-time data transmission. Because they orbit much closer to Earth compared to other types, LEO satellites can achieve detailed observations of atmospheric phenomena such as storm systems and pollution levels.

However, LEO satellites generally cover smaller geographical areas and have a shorter operational lifespan than their higher-orbit counterparts. Their path needs to be tracked and recalibrated frequently to maintain coverage.
Geostationary Satellites
Geostationary satellites orbit at an altitude of approximately 35,786 kilometers above the equator. This positioning allows them to remain stationary relative to the Earth’s surface. As a result, these satellites consistently monitor the same areas, making them invaluable for applications like weather forecasting and telecommunications.
Some key characteristics of Geostationary satellites are:
- Constant Coverage: They provide continuous observation of a particular region, which is pivotal for real-time weather monitoring and alerts.
- Wide Area Coverage: A single geostationary satellite can cover approximately one-third of the Earth’s surface, making them efficient for broadcasting purposes.
Despite their advantages, they have limitations like lower resolution images compared to LEO satellites, and their high altitude can introduce a delay in data transmission.
Polar Orbit Satellites
Polar orbit satellites travel over the poles at altitudes between 700 kilometers and 800 kilometers. These satellites follow a north-south trajectory, allowing them to scan the entire terrestrial surface over time. This makes them ideal for applications like climate tracking and environmental monitoring, where a comprehensive view of Earth’s surface is needed.
Important aspects of Polar orbit satellites include:
- Global Coverage: Over time, they can cover the entire surface of the Earth, providing essential data for global climate modeling and environmental assessments.
