Q

In what frequency band does a search and rescue transponder operate?

🔍 Key Concepts

• Radar SART (Search and Rescue Transponder) vs EPIRB (Emergency Position Indicating Radio Beacon) – know which uses 406 MHz • Difference between X‑band and S‑band marine radar frequencies • Typical frequency range in GHz used by ship’s X‑band radar that interrogates a SART

💭 Think About

• Ask yourself: Is a SART designed to respond to satellite signals like COSPAS‑SARSAT, or to a ship’s radar pulses? • Which marine radar band (X‑band or S‑band) is commonly required to be able to detect and paint a SART on its display? • Look at the numeric values: which option is closest to the standard X‑band radar frequency range used on ships (about 9‑10 GHz)?

✅ Before You Answer

• Verify which device (SART or EPIRB) is associated with 406 MHz in GMDSS systems • Confirm that S‑band marine radar is around 3 GHz, and compare that to the answer choices • Identify which answer choice falls in the X‑band radar range used for SART operation (about 9.2–9.5 GHz) before you decide
