JAVAD Giodis

Full-featured office post-processing software for high-precision geodetic and surveying applications with convenient user interface.

Solves a wide range of practical surveying tasks using advanced scientific approach.

Advanced post-processing

  • Baseline and session processing of zero-differenced GNSS data.
  • Automatic removal of trivial baselines.
  • Direct estimation of ionosphere, troposphere, and satellite/receiver clocks.
  • Uses global meteorological dataset to improve processing.
  • Uses ITRF control points to make processing more robust.
  • Calculates baselines up to 2000 km at the centimeter level of accuracy.

Network adjustment

  • Minimally constrained network adjustment of baselines and/or session subnets.
  • Fully constrained 1D, 2D and 3D network adjustment with vertical and/or horizontal control.
  • Allows merging control points and processed session subnets from different projects for their common adjustment.

Quality control for each step of data processing

  • Quality statistics for satellites and receivers.
  • Graphical analysis of phase and pseudorange data residuals.
  • Performs statistical tests to reject data outliers and get realistic accuracy estimate.

Internet download-manager

  • Unattended and explicit downloading of IGS and CORS data for over 7000 worldly distributed stations.

Coordinate systems

  • Extendable database with over 3000 global, national, and local coordinate system definitions, including transformation parameters and geoids.
  • Coordinate system editor for editing and adding new ECEF, horizontal and vertical systems.
  • Calculator to transform coordinates between two arbitrary coordinate systems.

Reference points catalogs

  • Storing and editing control point coordinates.
  • Obtaining high-accurate coordinates for permanent reference stations by given region from Scripps Epoch Coordinate Tool and Online Resource.

Antenna library

  • Extendable antenna library that includes IGS and NGS absolute and relative antenna calibration parameters, phase center variations, and physical dimensions.

Background maps

  • Detailed background maps covering the entire United States from the national level down to detailed street networks (TIGER data).
  • World maps of any location on Earth with common geographic features.

Mission Planning

  • GPS, Glonass, Galileo and SBAS satellite availability.

Reporting

  • Editable report generation (Excel document) for all steps of working on a project.
  • Support project notes and processing/adjustment logging.

Modern user interface

  • Uploading and processing data with minimal interaction.
  • Advanced user can manage internal data flow by explicit request.
  • High-quality visualization, reporting, and printing.
  • Multilingual support: English, Russian, and Spanish.

Data protection

  • Projects and point catalogs can be encrypted to protect business data.

Typical applications

  • High accuracy static and fast static surveys.
  • Creating local control networks.
  • Monitoring of permanent networks.
  • Easy and precise ties to high-accuracy ITRF frame (IGS/CORS stations).
