On which of the following does an automatic identification system (AIS) transponder transmit and receive information?
AI Explanation
You are correct, the correct answer is C) VHF maritime band.
AIS transponders operate on the VHF maritime band, specifically on the frequencies 161.975 MHz (AIS Channel 1) and 162.025 MHz (AIS Channel 2). This is in accordance with the International Maritime Organization (IMO) regulations for AIS, which specify the use of the VHF maritime band for AIS data transmission and reception.
The other options are incorrect because: A) AIS does not use 3 cm X-band radar, B) AIS does not use UHF L-band, and D) AIS does not use 10 cm S-band radar. AIS is a dedicated system that utilizes the VHF maritime band for its automatic identification and data exchange capabilities.
