Different types of Satellites
Satellites are artificial devices that orbit the Earth for various purposes. There are different types, each with specific functions and among the main ones are communication, navigation, Earth observation, scientific and military.
Communications satellites are used to transmit radio and television signals, as well as provide internet and telephony services.
Navigation satellites, such as GPS, are used to determine the location and trajectory of moving objects.
Earth observation satellites
They are designed to monitor the surface of the planet, collecting information about climate, oceans, agriculture, natural disasters, among others.
In turn, they are used to study the universe, collecting information about planets, stars and other celestial bodies.
They are employed for defense and national security purposes, monitoring the activities of other nations and detecting threats. Each type of satellite is essential for different areas, and its use has been increasingly widespread throughout the world.
What are the main satellites in the world?
As we have seen, many of the existing satellites are important for different areas, such as communications, Earth observation, science and technology. Below, I list some of the main satellites currently in orbit and their names:
- Brasilsat B
- Inmarsat 3
- Landsat 7
The Defense Support Program (DSP) is an early warning satellite system developed and operated by the United States to detect and track ballistic missiles around the world. The system comprises a constellation of satellites in geostationary orbit equipped with infrared sensors to detect the heat emitted by missile engines during launch.
It is a crucial part of the US missile defense system and provides early warning of potential enemy attacks, allowing the armed forces to respond quickly and effectively. The DSP program began in the 1960s and continues to be refined and updated to meet the national security needs of the United States.
The Global Positioning System (GPS) is a satellite navigation system developed by the United States to provide accurate positioning and navigation anywhere in the world. It consists of a network of more than 30 satellites in orbit, plus ground stations and GPS receivers in mobile devices, vehicles and aircraft.
It also provides accurate location, speed and direction information and is widely used in various applications such as marine and air navigation, transportation systems, emergency services, vehicle monitoring and general geopositioning. The satellite is maintained by the United States government, but can be used by anyone around the world who has a GPS receiver.
Terra is an Earth observation satellite launched by NASA in 1999. It is part of the Earth Observing System (EOS) program and is designed to collect information about the planet’s climate, atmosphere, land surface, geology, and biology. The satellite orbits the planet every 99 minutes and has five instruments on board that capture high-resolution images, as well as data on temperature, humidity, vegetation and other environmental parameters.
The information collected by Terra is used to improve understanding of the planet and help in decision-making on environmental issues such as climate change, natural disasters and biodiversity conservation. It is an important tool for scientists studying the globe and its environment, providing critical information for researching and monitoring global environmental issues.
Brasilsat B is a Brazilian communication satellite, developed by the Brazilian Space Agency (AEB) in partnership with Telebras and launched in 1985. It was the second satellite in the Brasilsat series and was designed to provide telecommunications services to Brazil and countries in South America. The satellite is equipped with 24 transponders in the C band and 12 transponders in the Ku band, allowing the transmission of voice, data, television and other communication services throughout Brazil and in some countries in the region.
The satellite operated successfully for over 20 years, being taken out of service in 2007 and was an important part of the Brazilian space program and helped to expand access to communications across the country and the South American region.
Inmarsat 3 is a series of geosynchronous communications satellites launched by Inmarsat, a British satellite communications company, between 1996 and 1999. They were designed to provide voice, data and fax communication services around the world, including remote regions. and maritime areas.
The Inmarsat 3 series satellites are equipped with high gain antennas that allow the transmission of signals to mobile devices and communication terminals in remote areas, in addition to providing global mobile telephone services and emergency communications.
This project was a major improvement over previous Inmarsat satellites, offering greater data and voice transmission capacity and helping to connect people around the world. Today, the satellite continues to operate and launch new satellites to offer communication services around the world.
Meteosat is a series of geostationary weather satellites operated by the European Space Agency (ESA) in partnership with the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT). The first satellite of this system was launched in 1977 and since then, several generations of satellites of the series have been launched.
The satellites in this system are designed to provide near real-time weather information for Europe, Africa and parts of South America and Asia. They are positioned in geostationary orbit at an altitude of 36,000 km and provide high-resolution images every 15 minutes. The images provided are used for weather forecasting, storm monitoring, natural disaster prevention and weather observation.
In addition, Meteosat also collects data on sea surface temperature, air humidity, winds, pollution and other meteorological parameters, helping to improve understanding of global climate and long-term weather forecasting. It is an important part of Europe’s Earth observation system and has been instrumental in weather forecasting and climate monitoring around the world.
Landsat 7 is an Earth observation satellite operated by NASA and launched in 1999. It is the successor to Landsat 6 and is part of the Landsat series, one of the oldest and most reliable sources of Earth observation data in the world. It orbits Earth at an altitude of 705 km and takes about 16 days to complete an orbit.
This satellite is equipped with an onboard image sensor known as the Enhanced Thematic Mapper Plus (ETM+), which is capable of capturing high-resolution images of the Earth’s surface in various spectral ranges, including visible, infrared and thermal. The captured images are used to monitor land use, vegetation, water, atmosphere and climate change.
It is an important tool for scientists studying the Earth and its environment, providing critical information for researching and monitoring global environmental issues. Unfortunately, in 2003, the satellite suffered a technical problem that affected the quality of the images, but it still remains an important source of data for observing the planet.
Earth’s most important satellite
It is not possible to define a single satellite as the most important on Earth, as there are many satellites that are essential for different areas such as communications, Earth observation, navigation and science. Therefore, each one is perfectly useful and functional within its area of operation.
