In summary, satellites are given a tangential velocity through a combination of vertical launch and horizontal acceleration, which allows them to achieve and maintain orbit in space. This process is often referred to as "rocket science" and can be explained in more detail through various resources, such as the link provided.

I guess the short answer is "that's rocket science"!
Basically the satellite is launched vertically to get through the lower part of the atmosphere, but then accelerates horizontally to achieve the necessary tangential velocity.
There's a good explanation here, for example:

FAQ: What gives satellites their tangential velocity?
What is tangential velocity?
Tangential velocity is the velocity of an object moving along a circular path, perpendicular to the radius of the circle at any given point.
How is tangential velocity related to satellites?
Tangential velocity is essential for satellites to maintain their orbit around Earth. It is the speed at which a satellite moves horizontally in its orbit.
What gives satellites their tangential velocity?
The tangential velocity of satellites is primarily determined by the gravitational pull of Earth. As the satellite orbits around Earth, it is constantly pulled towards the center of the planet, causing it to accelerate and maintain its tangential velocity.
How is tangential velocity different from orbital velocity?
Tangential velocity is a component of orbital velocity. Orbital velocity is the total velocity of a satellite, which includes both tangential velocity and the velocity towards or away from Earth, known as radial velocity.
Can satellites change their tangential velocity?
Yes, satellites can change their tangential velocity by using thrusters or engines to adjust their speed and direction. This is often necessary for satellites to maintain their orbit or to change their orbit for a specific purpose.
