Geo++ GmbH is a German company with many years of experience in the field of satellite-based positioning and related applications (e.g. dedicated software products and complete systems). The scope of applications of Geo++ comprises all components for positioning with Global Navigation Satellite Systems (GNSS) with emphasis on precise geodesy and navigation. The most important competence of Geo++ is a rigorous modeling using undifferenced GNSS observables. Hardware issues (e.g. oscillator and atomic clocks, antenna reception), atmospheric propagation effects and orbit modeling must be precisely accounted for. Geo++ is a driving force in the development of several new software technologies in positioning and navigation on a local, regional and global scale.
