Subcategory SPA Hardware
Version v1
Name TT SpaS 10
Description Table Top SPA, or TT-SPA for short, has been developed to enable the wider aerospace community to develop SPA-compatible solutions at their home sites. TT-SPA utilizes COTS versions of the core infrastructure components and integrated software utilities to offer the same development capabilities that were resident at the Responsive Space Testbed in Albuquerque through the course of PnPSat development, Integration and Test. TT-SPA houses a PowerHub and SpaceWire router with 10 SPA-S endpoints. Adding a PCIe SPA-S integrated card and interconnecting cabling provides an integrated development capability. TT-SPA also provides support for Test Bypass Interface. Each exposed port can be connected to a SPA-S compliant device (e.g. ASIM). This can include sensors, actuators, processing nodes, or additional TT-SPA’s to extend the SPA-S network to support a greater number of devices. The SPA-S PCIe card bridges SPA data messaging from the external SpaceWire network into a test workstation so that PnP devices may be integrated with development and test tools such as Star Technology Corporation’s SDT Data Browser. SPA software modules may also be run on the host PC or SPA-S Processing Node– interacting with simulation-resident device models or with real hardware residing on the TT-SPA physical network. Using the SPA Test Bypass protocol, the simulation may be used to supply test data to each attached device so that coordinated “day-in-the-life” style testing may be conducted.
