GNSS Signal Architect Product Suite

The NAVSYS GNSS Signal Architect suite of products provides GNSS simulation and test capability at very competitive prices. The GNSS Signal Architect Simulator Software allows users to specify a trajectory and complete set of simulation parameters to create an IQ data file at baseband or IF. The data file can be used for subsequent analysis with our GNSS Signal Architect Toolbox or can be used with a GNU Radio capable Software Defined Radio (SDR) platform to create a signal suitable for playback into a GPS or GLONASS receiver.

GNSS Signal Architect Simulator Software:

Create GPS or GLONASS Scenario Simulations
A software tool that creates simulations of GPS or GLONASS based on static or dynamic scenarios. Users can specify a complete set of simulation parameters, including receiver/satellite profiles and delay/noise error modeling. Playing back the simulation as an RF signal provides accurate and repeatable signals for GNSS receiver testing.


Record and Playback GPS or GLONASS Signals
GNSS Signal Architect allows you to choose the Software Defined Radio (SDR) platform that fits your needs and budget. The software provides the right tools to integrate with GNU Radio for customizing the platform to your project requirements.

Armed with the capability to expand to multiple radios and full frequency spectrum, GNSS Signal Architect puts GNSS testing and simulation under your control.



GNSS Signal Architect Toolbox:
GPS and GLONASS Data Analysis and Signal Processing

Signal Architect
  • Signal Simulation Tools: Simulates the effect of GPS and GLONASS satellite signals on a conventional receiver’s code and carrier tracking loops.
  • Geographical Tools: Facilitates the transformation of data between the various coordinate systems commonly used in GPS research.
  • Satellite Geometry Tools: Reads GPS and GLONASS almanacs and ephemerides and computes coordinates and line-of sight vectors to GNSS satellites, DOP values, and predicted satellite visibility.
  • Receiver Design and Analysis Tools: Models different receiver architectures and simulates different error scenarios such as urban environments, multi-path, and high-dynamic situations.
