G/T
G/T (Gain over Temperature) is an important measure used in satellite communications that shows how well a satellite system can receive signals. Think of it like a radio's ability to pick up stations clearly - the higher the G/T number, the better the system is at receiving weak signals from space. When reviewing resumes or job descriptions, you might see this term used when candidates talk about designing, testing, or improving satellite communication systems. It's similar to discussing the reception quality on a cell phone, but for space communications.
