Q

How might an installer verify correct GPS sentence to marine DSC VHF radio?

🔍 Key Concepts

• Digital Selective Calling (DSC) radios use GPS input (usually NMEA0183 sentences) for position and time. • Installers need a way to confirm the radio is actually receiving valid GPS data, not just wired. • Most modern DSC radios provide a GPS status/confirmation indication separate from just showing a position.

💭 Think About

• What information does the radio itself provide to tell you that GPS data is being received and decoded correctly? • Is simply seeing numbers on a screen always proof that the correct GPS sentence is being used and understood by the radio? • Which option represents a built‑in, intentional feature for confirming GPS input rather than an operational or test transmission?

✅ Before You Answer

• Check which choice refers to an internal GPS status/confirmation feature of the radio. • Eliminate any option that would involve transmitting unnecessarily on VHF just to check wiring. • Distinguish between merely seeing a position display and a specific indication that valid GPS data/sentences are being received.
