Doppler Speed Log DSL-200
Raytheon Anschütz Doppler Speed Log DSL-200 is identified in the source list as a speed log. It is installed on the bridge and at the associated sensor location, with outputs distributed to connected navigation equipment as required. Its purpose is to provide the vessel navigation parameter indicated by the category for bridge use and connected systems. The source record provides no additional model-specific operating figure beyond the listed designation and category. Sensor principle, correction methods, interfaces and redundancy depend on the exact model and vessel installation. The exact model designation distinguishes sensing technology, interfaces and accuracy class from neighboring instruments; refer to the manufacturer documentation for the exact figure.

Service & Maintenance
Compare the indicated value with independent references and investigate persistent disagreement rather than applying unrecorded corrections. Inspect sensors, cabling, power supplies, repeaters and network interfaces applicable to the installed equipment. Verify alarms and data outputs to radar, ECDIS, autopilot and voyage-data systems where connected. Keep calibration or configuration records current as appropriate to the sensor type. Protect exposed sensors from paint, deposits and water ingress. Refer to the manufacturer documentation for the exact figure for test, calibration and alignment procedures.
