In the movie, First Man (2018), Neil Armstrong is getting into Gemini 8 space craft. He overhears capcom voice:

CARNARVON CAPCOM: Guaymas, read you loud and clear. We have S band track. We have just locked up on T.M.

What is the meaning of "T.M"?

  • $\begingroup$ It won't help for Gemini-specific questions, but the annotated Apollo flight journals explain a lot of the jargon of the period. You might enjoy them. $\endgroup$ – Russell Borogove Feb 18 at 22:14

Most likely Telemetry.

Although usually TLM is used.

The "locking" terminology is explained here : What is carrier lock and bit lock?
