About
TSD provides comprehensive Ground Segment solutions, encompassing Electrical Ground Support Equipment (EGSE) and Special Check-Out Equipment (SCOE), Command & Telemetry Ground Units, and the TSD I/F Bridge. The EGSEs and SCOEs are developed with architectures capable of testing flight items in a representative hardware environment, utilizing both commercial and custom components to accurately simulate flight operative conditions regarding timing, bit rate, and parallelism. Notable flight heritage includes EGSE for PRISMA Hyper-Spectral Earth Observation Satellite, SCOEs for SENTINEL-3 Program (OLCI Camera, OLCI Instrument, MIL-STD-1553B), EGSE for ISS EML Digital Video System, SCOEs for ACS I/F and HK boards of SAR-LUPE and ARGO Satellite Management Units, Ground Support & Test Equipment for FOTON 12, M1, M2, M3 Payload Data Handling System, EGSE for VIRTIS Instrument (Rosetta Spacecraft and Venus Express), SCOE for USV On-board Software Integration and Validation, and Ground Support & Test Equipment for experimental modules on TEXUS, MINITEXUS, MAXUS, MASER sounding rockets, and a Transportable Ground Station for a Stratospheric Balloon Telecommand System.
Command & Telemetry Ground Units feature a PC-based architecture with Windows OS, an FPGA-based PCI Board for hardware coding/decoding, a user-friendly HMI, wide configuration parameters, high integration, and enhanced performance. They interface with Modulators and Bit Synchronizers via RS422 Data + Clock. TM GSE functionalities include Viterbi Decoder, NRZ-M to NRZ-L Decoder, Pseudo De-Randomizer, Reed Solomon Decoder, Frame Synchronizer, CCSDS FRAME Decoder, and CCSDS TM source packets Reassembly. TC GSE functionalities include CCSDS TC Encoding, COP-1 Procedures, and TC Authentication Layer.
The TSD I/F Bridge is a general-purpose communication device designed for complete testing of flight units across development, pre-flight, and post-flight phases. It bridges on-board interfaces (e.g., SpaceWire, SerDes) with standard Ethernet. Key features include an open architecture customizable with various I/F circuits via internal expansion boards, a fully integrated solution with a user-friendly MMI, a standard 2U unit for desktop mount (optionally 19” rack-mountable), air cooling, and a standard 230Vac power input. The unit is based on a proprietary main board with a state-of-the-art FPGA and embedded microcontroller. Baseline interfaces like Ethernet, UART, SpaceWire, and CameraLink are on the main card, with controllers embedded in the FPGA for improved integration. Custom interfaces can be implemented on mezzanine cards, with expansion connectors routed directly to the main board FPGA.
