JCY-1800 AIS Transponder
JRC JCY-1800 AIS Transponder — Navigation & Bridge Equipment. The supplied category identifies the equipment as AIS Transponder (Class A), and it is normally installed on the bridge with VHF and GNSS antenna arrangements and interfaces to heading, speed and position sensors. In that listed role, its primary purpose is to transmit and receive structured vessel identity, position, course, speed and voyage information. Unlike radar, AIS relies on cooperative radio transmissions from equipped stations and on correct own-ship data and sensor inputs. Within the supplied list, neighbouring variants are distinguished by their model designations and naming, while the source does not state further model-specific hardware differences. No additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
