Abstract: Method and systems for executing an interactive computer simulation of a simulated vehicle. A central repository comprises a synthetic natural environment database (SNEDB) that comprises data for a plurality of geographically-located terrain skin representations of a computer generated. A remote data management system maintains the remote repository comprising a subset of the SNEDB accessible to an interactive computer simulation station. The interactive computer simulation station sends, over the network, a data request for geographical locations from the SNEDB and allows users to interact in the interactive computer simulation for controlling the simulated vehicle. The remote data management system computes a plurality of expected geographical positions for the first simulation station and anticipatorily updates, via the network, the subset of the SNEDB stored in the remote repository with a supplemental subset of the SNEDB corresponding to one or more of the computed expected geographical positions.

Abstract: A drive wheel for a track system having an endless track that has first, second, and third drive wheel engagers is disclosed. The drive wheel has a hub, a body, a rim, a plurality of first, second and third track engagers radially disposed on the rim. Each of the plurality of second track engagers are operationally aligned with one of the plurality of first track engagers. The plurality of third track engagers are on at least one lateral side of the plurality of first track engagers. The plurality of first, second and third track engagers are configured to, respectively, driveably engage with a first, second, and third drive wheel engagers of the endless track. An endless track and a track system are also disclosed.

Abstract: Method and systems, for executing an interactive computer simulation of a simulated vehicle, comprising a remote data management system, a central repository, a remote repository and an interactive computer simulation station. The central repository comprises a synthetic natural environment database (SNEDB) that comprises data of a plurality of data types for geographically-located terrain skin representations. The remote data management system maintains the remote repository storing a subset of the SNEDB. The station comprises data consumers each requiring one or more data types and sends, over the network, a data request for geographical locations from the SNEDB. The station allows users to interact in the simulation for controlling the simulated vehicle. The remote data management system determines a set of data types considering requesting data consumers and updates the subset of the SNEDB for the geographical locations with data of only the set of data types.

Abstract: Method and systems for executing an interactive computer simulation of a simulated vehicle comprising a remote data management system, a central repository, a remote repository and an interactive computer simulation station. The central repository stores a synthetic natural environment database (SNEDB) that comprises data records for a plurality of geographically-located terrain skin representations of a computer generated environment. The remote data management system maintains the remote repository storing a subset of data records from the SNEDB. Each one of the subset of data records has a priority tag. The station sends a data request for geographical locations from the SNEDB and allows users to interact in the simulation for controlling the simulated vehicle.
