Some disadvantages of active satellites include the risk of collision with other space objects, vulnerability to space debris, the possibility of signal interference, and the challenge of managing and maintaining the satellite's operational life.
Disadvantages of satellites include high costs for manufacturing and launching, vulnerability to space debris and damage from solar radiation, limited lifespan due to fuel constraints, and potential for signal interference.
Russia has 1,324 the united states has only 658.
There are more than 800 active satellites currently in orbit. They represent four percent of the total number of objects currently cataloged by the U.S. space surveillance network; the rest includes abandoned satellites, spent rocket boosters, and other debris. The United States owns more than 400 active satellites, just over 50 percent of all satellites. Russia and China have the second and third highest number of space assets, owning 89 and 35 satellites, respectively. Civilian satellites, which perform tasks for the commercial, scientific, and government sectors, make up the majority of U.S. satellites. Russia's space assets are split nearly evenly between military and civil missions, though there are not separate military and civilian space programs. Only a very small percentage of other countries' satellites are military in nature. www.ucsusa.org/nuclear_weapons_and_global_security/space_weapons/technical_issues/satellites-types-orbits.html
As of 2021, there are around 80 countries with active satellites in orbit around Earth. These satellites serve various purposes including communication, weather monitoring, Earth observation, and scientific research.
Satellites cannot orbit the US; they orbit the Earth, and there are several thousand of them.

What are the advantages and disadvantages of active immunisation?
The names of the active satellites on the A Train constellation are GCOM-W1, Aqua, CloudSat, Calipso and Aura. They are Earth observation satellites in sun synchronous orbit.

There are thousands of satellites in Earth's orbit, with estimates ranging from 2,200 to over 3,000 active satellites. Additionally, there are many more inactive or defunct satellites and debris in orbit.
Disadvantages of satellites include high costs for manufacturing and launching, vulnerability to space debris and damage from solar radiation, limited lifespan due to fuel constraints, and potential for signal interference.
active satellites are receives the transmitted signal from earth ,amplify the signal and transmit it. it is also called as transponders. but passive satellites just receive and transmit the signal.itac as the reflector
The advantages of Active Server Pages are that they provide a powerful scripting language and it is compatible with HTML. The disadvantages of Active Server Pages are that the coding is complex and the connections are stateless.
