🔍 Key Concepts

• How antenna position (bearing) data is turned into an electrical signal for the display • The difference between synchros, resolvers, and encoders as angle‑sensing devices • What most marine RADAR/ARPA installations have historically used for antenna bearing transmission

💭 Think About

• Think about which of these devices can continuously transmit angular position over 360° with good accuracy and robustness in a marine environment. • Which option is most commonly associated with traditional marine RADAR and ARPA equipment you’d see on commercial ships? • Ask yourself whether the question is looking for a specific, standard method or saying that all listed methods are equally acceptable.

✅ Before You Answer

• Verify which devices are standard in older and conventional shipboard RADAR systems (hint: used for bearing repeaters and scanners). • Consider whether optical encoders are typically exposed to harsh weather at the scanner or are more often found in enclosed, clean environments. • Check if the exam you’re studying from tends to expect the traditional, regulatory/industry standard method rather than all possible modern technologies.
