Operationally Responsive Space (ORS) Office’s Website

Design Net Engineering is developing the command and data handling (C&DH) system and core software as well as the power management and distribution system (PMAD) for the Operationally Responsive Space (ORS) T2E spacecraft as a subcontractor to Northrop Grumman. The MSV ORS T2E spacecraft bus is the first spacecraft of its kind to fly the Space Plug & Play Avionics (SPA) open architecture components and network.

Design Net is developing the Command and Data Handling (C&DH) subsystem consisting of nine flight Applique Sensor Interface Module (ASIM) and one SPA Spacewire Network router with flight software integrated with a BroadReach processor for delivery in first quarter 2013. Each ASIM integrates with one or more spacecraft heritage hardware component such as a star tracker or sun sensor. The Power Management and Distribution (PMAD ) subsystem provides a bus switching unit, configurable charge control module, configurable array bus controller and a subsystem processor and is SPA based to fit seamlessly into the MSV T2E spacecraft.

Air Force Research Laboratory Website

Design Net developed for the Air Force Research Laboratory (AFRL) the Intelligent Data Handling (IDS), Solar Array Controller, Energy Management Subsystem and Plug and Play (PnP) Flight Software. All components were developed for the AFRL modular reusable PnP demonstration spacecraft bus. When the flight mission was canceled the components were used to create a FlatSat for PnP demonstrations.

Floating Potential Probe – NASA

Design Net developed for Glenn Research Center a small spacecraft called the Floating Potential Probe (FPP) to measure electrical potential between the International Space Station (ISS) and the surrounding plasma before new solar panels were installed. The FPP was astronaut and EVA rated and was installed as a fixed probe on the ISS by astronauts.

  • Astronaut and EVA Rated
  • Holds Record for Delivery of ISS Man Rated Hardware
  • Completed in 5 Months
