What Does PMF Stand For?

PMF stands for Perigee Motor Firing

PMF, or Perigee Motor Firing, refers to the precise ignition of propulsion systems at a spacecraft's perigee, which is the point in its orbit closest to Earth. This maneuver is critical for optimizing orbital insertion, increasing velocity, or adjusting trajectory. By executing PMF, spacecraft achieve targeted orbital adjustments efficiently, leveraging the gravitational pull of the Earth to enhance propulsion effectiveness.
