RF means Radio Frequency. This did mean broadcast radio/TV or at least some high powered transmitter in the past, but today could apply to many lower powered applications, down to WiFi and Bluetooth.
What is rf transmitter
It's a encoder for RF transmitter
depends on frequency and power
An rf link transmitter is used to connect different repeaters together in a wireless network. A repeater is used to strengthen a wireless signal and provide better coverage.
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
No, TV remotes use IR light and/or RF transmitter.
exciter is a component in a electrical generator and or the low power rf stages of a radio transmitter
RF direction finders use antennas to receive radio frequency signals from a transmitter. By comparing signal strength or phase differences at multiple antenna locations, the direction to the transmitter can be determined. This information helps locate the source of a radio signal.

I'm assuming you are talking about GPS when you say "satellite." RF tracking can be directional. It takes three RF receiver stations to triangulate the position of an RF transmitter and is usually less accurate than GPS. RF is also more limited by range, so the RF tracking stations are usually required to be mobile depending on the strength of the transmission signal.
RF = Radio Frequency
AF modulator. Audio signals produced by the microphone get amplified enough with the power to modulate the RF carrier wave generated by a RF oscillator.
