SSAS-100

JRC (Japan Radio Co) SSAS-100 — Navigation & Bridge Equipment. The supplied category identifies the equipment as AIS Transponder, 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.

Common failures & inspection points

GNSS, heading or speed-input failure causes invalid dynamic data and sensor alarms
VHF antenna or feeder faults reduce transmit and receive range and may trigger built-in-test warnings
Incorrect static or voyage data results in wrong vessel information being transmitted
Power-supply or network faults cause unit resets, blank displays or loss of target data to bridge systems
Internal transceiver or timing faults cause transmission alarms or missing nearby targets

Service & Maintenance

Verify own-ship static and voyage data, sensor inputs, antenna condition, alarms and target reception. Compare transmitted information with approved vessel particulars. Check interfaces to ECDIS, radar and pilot connections where fitted. Refer to the manufacturer documentation for the exact figure for radio-performance and service criteria.
