Focus

Software instead of hardware

The examples show pure software development: parsers, interfaces, data models, dashboards, analysis and integrations.

Billing

Hourly basis

Projects are not sold as rigid products, but planned, implemented and extended individually on an hourly basis.

Use cases

B2B and special cases

Suitable for shipyards, installers, fleet operators, maritime startups and software companies that need protocol and integration expertise.

Selected examples

Realistic project types that occur in practice

The following case studies are written as representative project examples. They show what kinds of tasks Upwind Engineering can take on without disclosing specific customer data.

NMEA 0183 01

NMEA data stream for an existing web application

Typical customer: Maritime software company

An existing system needed to process position, course and sensor data from NMEA 0183 without rebuilding the existing architecture.

3

Data sources

24/7

Planned operation

JSON

Target format

Initial situation

The data came from multiple serial sources, was sometimes incomplete and had to be made available to a web application in real time.

Implementation

Development of a stable parser with validation, timestamps, error handling and JSON output through an internal API.

Result

The application was able to display and store live maritime data reliably. Invalid records were logged without interrupting the data flow.

Services used

NMEA parser JSON API Error handling Backend integration
AIS / GPS 02

Preparing AIS and GPS data for fleet overview

Typical customer: Small fleet operator

Position and movement data from several workboats had to be stored in a structured way and made usable for internal analysis.

AIS

Data source

SQL

Storage

CSV

Export

Initial situation

AIS and GPS data existed in different formats. The data had to be normalized, filtered and stored for later analysis.

Implementation

Development of a position data pipeline with plausibility checks, database storage and export options for reporting and analysis.

Result

The customer received a clean technical foundation for route analysis, operational reports and future dashboard extensions.

Services used

AIS processing GPS data SQL database CSV export
Signal K 03

Signal K integration for custom monitoring

Typical customer: Refit project

In an existing setup, maritime data needed to be processed through Signal K and connected to a custom monitoring interface.

Live

Data mode

WebSocket

Interface

Modular

Architecture

Initial situation

The data was already available, but not usable for the customer in the required form. A clean interface between Signal K and a custom frontend was needed.

Implementation

Connection to Signal K, selection of relevant data paths, transformation of the data structure and delivery through WebSocket for a custom frontend.

Result

The monitoring interface was able to display live data such as speed, course, depth and system states in a clear way.

Services used

Signal K WebSocket Live data Frontend integration
Data analysis 04

Analysis of faulty NMEA log files

Typical customer: Marine electronics installer

An installer needed support analyzing log data in order to narrow down sporadic failures and faulty data records.

Logs

Input data

Report

Output

Script

Implementation

Initial situation

The errors did not occur continuously. Manually reviewing the log files was too time-consuming and did not provide a clear overview.

Implementation

Development of an analysis script to detect invalid checksums, missing fields, outliers and temporal gaps in the data stream.

Result

Troubleshooting was significantly accelerated. The installer was able to explain to the end customer which data was suspicious in a clear and traceable way.

Services used

Log analysis Checksum validation Diagnostic report Automation
APIs 05

Providing maritime data through a REST API

Typical customer: B2B software provider

A software provider wanted to integrate maritime device data into an existing platform without building internal NMEA expertise.

REST

API type

B2B

Use case

Docs

Handover

Initial situation

The platform worked with REST APIs, while the maritime data came from NMEA-like raw data streams.

Implementation

Design and implementation of a middleware layer that processes, normalizes and exposes maritime raw data through documented REST endpoints.

Result

The customer’s development team was able to use the data like any other internal API. Maritime protocol details remained encapsulated.

Services used

REST API Data model Backend Documentation
Dashboard 06

Custom dashboard for maritime operational data

Typical customer: Technical project team

An internal project required a web-based dashboard that presents selected maritime data in an understandable way.

Web

Interface

UX

Focus

API

Integration

Initial situation

The data was technically available, but difficult to interpret for project stakeholders without protocol knowledge.

Implementation

Development of a clearly structured web interface with status cards, time series, data quality indicators and API integration.

Result

Technical and non-technical stakeholders were able to understand the system state more quickly and make decisions based on the data.

Services used

Web dashboard UX API integration Data visualization
