📡 TIDEMARK-1 Health Check | SignalRange Tutorial

Your first day at North Atlantic Teleport Services — a commercial satellite ground station in rural Vermont. Senior operator Charlie Brooks has three new hires to train before he transfers to Europe, and not much time to do it. Today you watch, he explains.

TIDEMARK-1 is already online at 53°W, serving maritime broadband traffic for SeaLink Global Communications. This scenario walks you through a complete ground station health check — the routine every operator runs at the start of every shift.
What You'll Learn:

GPSDO (GPS Disciplined Oscillator) — the timing heartbeat of the entire rack
LNB noise temperature — why lower Kelvin means better receive sensitivity
HPA states and safe operating conditions
Antenna tracking modes (program-track vs step-track)
Polarization alignment and why cross-pol kills your signal
Reading a spectrum analyzer — finding the beacon in the noise
Receiver modem C/N ratios — what "good margin" actually looks like
I&Q constellation diagrams — visual health of your demodulated signal
Dashboard alarm management

Duration: 25-35 minutes
Difficulty: Beginner
Prerequisites: None — this is where everyone starts

No pressure, no live transmissions, no customer calls. Just observation and familiarization. Learn what "normal" looks like before anything goes wrong.
