GART-2000® navigation is a project-related, hardware-independent realtime and analysis software with a modular structure, which is especially suitable for dynamic applications. GART-2000® navigation primarily controls the multi-antenna systems from JAVAD GNSS and is open to the integration of further sensor systems. The relevant navigation data are visualized, archived, and available for subsequent processing. A link with an Inertial Measurement Unit (IMU) is also implemented, which enables the high-precision determination of position and location even under obstructions (e.g. beneath bridges).
