Satellites: Their Orbits, Tracking Systems, and Essential Uses

Satellites: Their Positions, Tracking, and Importance

Satellites have become an essential part of modern life, orbiting Earth and providing us with services ranging from communication and navigation to weather forecasting and space exploration. As of 2024, thousands of active satellites are circling our planet, each performing a specific role to enhance the quality of life on Earth. This article delves into the positioning of satellites, how they are tracked, what they track, and the significance of their roles.

Types of Satellite Orbits and Their Positions

Satellites are positioned in various orbits depending on their intended functions. These orbits determine how close the satellite is to Earth, how fast it moves, and what areas it covers.

Low Earth Orbit (LEO): Altitude: 180 km to 2,000 km Satellites in LEO include most Earth observation satellites, the International Space Station (ISS), and some communication satellites. These satellites are closer to the Earth, enabling them to capture high-resolution images. Functions: Used for imaging, remote sensing, and some communication purposes. Examples: ISS, Earth observation satellites like Landsat.

Medium Earth Orbit (MEO): Altitude: 2,000 km to 35,786 km Satellites in MEO are mainly used for navigation. This orbit offers a good balance between coverage and latency. Functions: GPS satellites and other global navigation systems. Examples: GPS, GLONASS, and Galileo satellites.

Geostationary Orbit (GEO): Altitude: 35,786 km above the equator Satellites in GEO move at the same rotational speed as Earth, meaning they stay fixed over one location on Earth. These are mostly communication and weather satellites. Functions: Used for television broadcasts, weather monitoring, and some types of communication. Examples: Weather satellites (GOES series), telecommunication satellites.

Highly Elliptical Orbit (HEO): Orbit shape: An elongated orbit with one point closer to Earth (perigee) and another point much farther away (apogee). Functions: Ideal for regions at high latitudes, providing prolonged coverage over areas like Russia and parts of Canada. Examples: Molniya satellites for communication in Russia.

How Satellites Are Tracked

The sheer number of satellites in space, combined with space debris, means tracking them is essential to avoid collisions and ensure their functionality. Ground stations and dedicated space agencies continuously monitor satellites. Several methods are used to track satellites:

Radar and Ground-Based Systems: Ground stations use radar to track satellites in LEO. These systems bounce radio waves off the satellite and measure the time it takes for the signal to return. By doing this repeatedly, they can track a satellite's location and speed.

Global Positioning System (GPS): Satellites in higher orbits like MEO or GEO are tracked using onboard GPS receivers. GPS helps calculate the satellite’s position and relay that data back to Earth.

Optical Tracking: Telescopes and cameras are used to visually observe satellites in higher orbits. This method is particularly useful for tracking objects that do not emit radio signals or need to be monitored for their physical characteristics.

Space Surveillance Networks: Agencies such as the U.S. Space Surveillance Network (SSN) and similar organizations in other countries continuously monitor satellites and space debris. They catalog objects and issue alerts for potential collisions.

What Satellites Track

Satellites are equipped with various sensors, cameras, and instruments to track a wide array of data on Earth, in space, and beyond:

Weather and Climate Data: Satellites such as NOAA’s GOES series monitor weather patterns, hurricanes, and long-term climate changes. They provide crucial data for meteorological services.

Earth Observation: Satellites like Landsat capture high-resolution images of Earth's surface. These images are used for mapping, agricultural planning, disaster response, and environmental monitoring.

Navigation Signals: GPS and other GNSS (Global Navigation Satellite Systems) satellites send signals that are used for navigation by smartphones, vehicles, ships, and airplanes worldwide.

Communication: Satellites facilitate global communication by relaying TV, radio, and internet signals across vast distances.

Space Exploration: Space telescopes like the Hubble Space Telescope track distant galaxies, nebulae, and black holes, helping scientists study the universe.

Military Surveillance: Many satellites are designed for defense purposes, tracking missile launches, military movements, or spying on potential threats.

Number of Satellites in Space

As of 2024, there are approximately 8,000 operational satellites orbiting Earth. The exact number fluctuates as new satellites are launched and old ones are decommissioned. Additionally, space agencies and private companies like SpaceX continue to launch large satellite constellations, such as Starlink, which alone has over 5,000 satellites in orbit for global internet coverage.

The Usefulness of Satellites

Satellites have become indispensable in modern life, serving a wide variety of purposes that impact everyday activities and critical global functions:

Key Functions of Satellites:

Communication: Satellites enable long-distance communication by transmitting data, television, and internet services. Without them, global broadcasting and real-time communication in remote areas would be impossible.

Navigation: Systems like GPS help millions of people navigate in real-time. They are also vital for the functioning of aviation, maritime travel, and even agricultural practices.

Earth Observation: Satellites provide high-resolution imagery of Earth, helping with disaster management, urban planning, agriculture, and environmental monitoring. For instance, they can track deforestation or observe glaciers' melting rates.

Weather Forecasting: Weather satellites provide the data needed for accurate predictions, storm tracking, and climate monitoring. This information is critical for preparing for natural disasters like hurricanes or floods.

Scientific Research and Exploration: Space telescopes and interplanetary satellites gather data on space phenomena, expanding our understanding of the universe. Satellites also conduct scientific experiments in the microgravity of space.

Defense and Security: Satellites are used for military surveillance, early-warning systems, and missile detection, playing a crucial role in national security.

Satellite Highlights in Brief:

Types of orbits: LEO, MEO, GEO, HEO, each serving different purposes.

Tracking methods: Radar, GPS, optical tracking, and space surveillance networks.

Data tracked by satellites: Weather, Earth observation, navigation signals, space exploration, and military surveillance.

Number of active satellites: Approximately 8,000.

Key roles: Communication, navigation, weather forecasting, Earth observation, scientific research, and defense.

In conclusion, satellites are essential tools for global communication, navigation, monitoring Earth's environment, and scientific discovery. As technology advances and the number of satellites continues to grow, their impact on our daily lives will only increase. Whether improving how we predict the weather, navigate through traffic, or explore the universe, satellites will continue to be a critical resource for humanity.

So you found a dead body in the woods

The worst thing you've worried about, going on hikes, happens. This happens often, in the grand scheme of things. It's always joggers and dogwalkers and hikers. My unlucky day came on October 24, 2022.

So what do you do when you find a dead body?

Look in the other direction and take a breath. Panic wont help you or them.

If you are comfortable, approach them and try to help. If not, it's okay. I was unwilling to approach (they looked real dead) and my 911 operator was 100% totally supportive and okay with that.

Walk a little ways away. There is no reason why you need to keep staring at them. It's okay. Seeing a dead person is really wack!

When you've caught your breath, call 911. My first thought was "Oh god, I don't want to talk to cops." and, good news, it's not cops! 911 responders are different people. They are trained to talk to you, to reassure you, and to help you. They are there for you. They understand you are freaking out. They are kind and patient.

Your new buddy, the 911 person, will help you figure out where you are, exactly. They have access to your location via cell-tower and GPS, but if, like me, you were off-trail (oops), they might need your help navigating to you. I offered to also send a photo, and he provided an email, which he received immediately. I deleted the photo I took right away.

Hang out on the phone with your dispatch friend. They're going to want to keep in touch with you as the paramedics approach. Are you freaking out by chattering too much? Are you freaking out by being dead silent? Both are okay! Apparently, my panic response is to become Super Midwestern Chatty. I was able to make him laugh, which I count as a win.

Holler to the paramedics. My paramedics came deep into the ravine-filled woods, about six men, steering a rolling bed thing. We shouted at each other until they made it to the body. It would have been funny, watching them fumble along, if it wasn't so serious.

Get out of there! The paramedics don't need anything from you. They're busy doing their job. They shooed me back to the trail and to the parking lot. I didn't have to go anywhere near the body.

Meet cops in the parking lot. In my situation, the cops didn't want anything from me. They were just picking their noses in the parking lot while the paramedics did the real work. The cops said thanks for helping, while covering their bodycams, because they're pigs.

Go eat donuts. Christ, that was a lot. Let yourself comedown and get some sugar to kickstart your system.

Feel good that you gave a family closure. Yeah, that sucked. Yeah, your therapist is going to hear about this. Yeah, next time you come to this location, you're going to need a friend with you. But you did the right thing. You'll never know their family, but know that you gave them closure.
