The Replicator

The Replicator would be your best choice for advanced GNSS R&D All civil GNSS signals with full control over the signals, NAVDATA, signal propagation models. Various models and variants are available to satisfy various needs for research, development and testing. Reference Station Receiver Data Generator allows to generate raw data and then RF signals for up to four locations with spatially correlated models

Overview

Some of the advantages
  • User defined models with ANSI C Model API.
  • User defined additional signals with ANSI C Signal API.
  • GNSS signal analysis

Components:

  • Replicator? 19 inch rack mount hardware ,
  • ReGen? control software ,
  • Optional ARAMIS? software receiver for signal analysis.

The Replicator? is a result of our 7-year work for and collaboration with the Japan Aerospace Exploration Agency (JAXA).

Software

The ReGen? is a control center software for multi-frequency, multi-system GNSS simulator. It is intended for advanced R&D, equipment testing and education.

Options

  • Comprehensive simulation models including atmosphere, multipath etc.(see ReGen data sheet)
  • Signal analysis.
  • Simulated signals can be stored in digitized format , analysed by a MATLAB software receiver and played back as RF at any time.

Reference Station Receiver Data Generator allows to generate raw data and then RF signals for up to four locations with spatially correlated models. The signals can be played back as RF signals. This option is useful for RTK, VRS or LAAS simulation.
