Protocol analyzer and simulator for navigation messages
Protocol analyzer and simulator for navigation messages

qmtseamen test of navigation units which allow to estimate the position relative to the starting point, as well as other data such as speed, roll, pitch, heading, ...

Information from the navigation center is broadcast in the form of messages for use by other vehicle systems. qmtseamen controls and analyzes the distribution of these messages which must meet very strict criteria of encoding, transmission periodicity, values contained, transmission latency, etc.

qmtseamen has been specifically developed to test naval navigation systems in two real-time operating modes. The analysis mode makes it possible to check the quality of the messages broadcast very precisely, while the simulation mode makes it possible to replace navigation equipment, by broadcasting the messages as in real conditions.

The strengths of QMTSeaMen
  • A high performance deterministic system based on a real-time and FPGA architecture
  • An analyzer mode designed to facilitate the control and use of data
  • A simulator mode that allows you to recreate the recorded or scripted conditions
  • User interfaces designed to facilitate analysis

Acquisition and processing of signals with software, hardware, acquisition hardware and sensors

Autonomous, they are dedicated to measurement for control by sampling in production and for the laboratory

Completely automatic from the feeding of the parts to the control: any non-conforming part is thus ejected and therefore the quality control is 100% guaranteed

Embedded and distributed systems

They operate autonomously with acquisition, processing and control to supervise and automate
