Northrop Grumman 8103FL01106036LH1A VoyageMaster II S-VDR Playback & Analysis Software

The Northrop Grumman Sperry Marine 8103FL01106036LH1A VoyageMaster II Simplified Voyage Data Recorder (S-VDR) Playback Software is an industrial-grade, type-approved diagnostic and incident analysis software suite. Engineered specifically for commercial vessel operators, accident investigators, and marine superintendent teams, this software suite parses, synchronizes, and plays back raw sensor feeds captured by the VoyageMaster II S-VDR Data Acquisition Unit (DAU).

By decoding proprietary binary streams extracted from the S-VDR’s protective data capsule or removable hard drive, the software reconstructs the vessel’s bridge telemetry in real time or accelerated speed. It provides synchronized visual and audio reconstruction of bridge communications, dual-channel radar/ECDIS video feeds, NMEA 0183 (IEC 61162-1/2) sensor data, and discrete contact closures.

Model Details

• Manufacturer: Northrop Grumman Sperry Marine
• Exact Manufacturer Part Number (MPN): 8103FL01106036LH1A
• Software Version/Series: VoyageMaster II S-VDR Playback & Extraction Utility
• Core Functionality: Multi-channel audio decoding, NMEA data stream telemetry reconstruction, radar/ECDIS frame rendering, and incident log extraction.

Key Technical Features

1. Synchronized Multi-Stream Playback: Reconstructs 4x bridge microphone feeds, 1x VHF radio channel, dual radar/ECDIS video frames, and NMEA navigational sentences on a single time-locked master clock.
2. Real-Time & Off-line Incident Analysis: Allows shore-side superintendents and onboard officers to perform live data monitoring via shipboard LAN or post-incident analysis from extracted storage media.
3. Customizable Conning & Data Displays: Enables custom display layouts for vessel position (GPS), speed log (STW/SOG), gyro heading, depth below keel, engine orders/responses, and rudder feedback.
4. Cryptographic Data Security & Access Controls: Implements password-protected administrative tiers and cryptographic hash verification to ensure evidentiary data integrity during incident reporting.

System Applications

• Incident & Casualty Investigation: Detailed forensic playback of bridge conversations, rudder/engine movements, and radar targets leading up to collision or grounding events.
• Navigational Training & Auditing: Replaying actual voyage logs to evaluate bridge resource management (BRM) practices and train deck officers.
• SOLAS Annual Performance Testing (APT): Used by certified radio/VDR survey engineers during annual survey inspections to verify proper data recording across all interfaced sensor channels.
• Fleet Performance Monitoring: Analysis of propulsion response, hull stress alarms, and weather conditions during specific passage legs.

Field Installation & Data Extraction

• When connecting a laptop directly to the VoyageMaster II Data Acquisition Unit (DAU) on the bridge:
• Ensure your static IP configuration matches the VoyageMaster LAN subnet (typically 192.168.0.x).
• Always verify that audio driver codecs (PCM/G.711) are properly registered in Windows before initiating playback; missing audio codecs can cause playback timeline desynchronization with the radar video stream.

Frequently Asked Questions

What hardware is required to run the VoyageMaster II playback software?

A standard Windows PC or laptop with an Intel Core processor, 4 GB RAM, an RJ45 Ethernet port, and a minimum screen resolution of 1024×768 is required.

Can I extract S-VDR data remotely over the ship’s satellite network?

While small NMEA text logs can be extracted over LAN/satellite connections, high-bandwidth radar image streams and raw multi-channel audio are best extracted via direct physical LAN connection or from the removable hard drive bay.

What should I do if audio channels fail to play back while radar video works?

This usually indicates a missing audio codec on the host PC or an incorrect sound device output assignment within the software configuration menu. Ensure the host system audio drivers are fully updated.

Is this software legally compliant for accident investigation reports?

Yes, the playback software generates time-stamped, unalterable data streams compliant with IMO MSC.163(78) and IEC 61996 standards for official maritime casualty investigations.
