Advanced mission simulation and analysis tool
The Orbit Determination Toolbox (ODTBX) is developed by the Navigation & Mission Design branch at NASA Goddard Space Flight Center as an advanced mission simulation and analysis tool used for concept exploration, proposal, early design phase, and/or rapid design center environments. ODTBX functions and utilities are combined in a flexible architecture that allows for modular development of navigation algorithms and simulations. The core ODTBX functionality is realized through a set of estimation commands that incorporate Monte Carlo data simulation, linear covariance analysis, and measurement processing at a generic level.
VALARI is a Virtual Announced Launch And Recovery Informant for Mac OSX for GPS & Telemetry tracking of modern high power rocketry. Eventually we might port this to other OSes.
