How often are the time signals broadcast by WWV and WWVH transmitted?

🔍 Key Concepts

• WWV and WWVH are U.S. standard time and frequency stations operated by NIST • These stations provide continuous time and frequency information over HF (high frequency) radio • Consider whether mariners need time info only occasionally or on an ongoing basis

💭 Think About

• Think about how often accurate time is needed for navigation, celestial sights, and radio operations—would short, infrequent bursts be enough? • Ask yourself whether these stations work more like a regular scheduled broadcast, or more like a reference signal you can tune to at any moment. • Compare each option to how a "standard time reference" is most useful to ships and other users worldwide.

✅ Before You Answer

• Confirm whether standard time stations are designed so users can tune in at any time and immediately get usable signals. • Consider if a 15, 30, or 60 minute schedule would make mariners wait too long for a signal when they need accurate time now. • Recall from your study materials how WWV/WWVH are described: "time and frequency signals are ..." and note whether the phrase suggests continuous or periodic transmission.
