Usability

Complete automation. End-to-end automatic operations.

Complete positioning system. IGDG handles all aspects of a complete real time global positioing system, including GPS orbit determination and simultaneous network positioing. Embedded, the software performs user positioining and orbit determination.

Highly portable. IGDG has already been ported to the following systems: VX Works, Linux, Unix, PowerPC, Windows NT

Versatile. Works with all types of geodetic receivers currently in IGS network: TurboRogue, Benchmark ACT, Ashtech Z12

Support available. Support is available in the form of manuals, online help, specialized training courses, and open-ended consultations.

Visual aids. Real time graphic display of performance using network monitoring tools and internal quality control.

Quality Factors

ANSI C for portability, maintainability.

Modularity. Highly modular code to support embedded as well as ground applications.

Reliability. Built for continuous, reliable commercial operations

Accuracy. All models are sub-cm accurate for the most demanding science applications.

Maintainability. Designed for operations by a third party and for team maintenance. Configuration control management.
