Customized RTUs can be composed of a variety of available functional modules, in units comprising from three up to 16 modules.  \nDue to its modularity and low mass and volume compared to the high degree of functionality, the concept allows a customization of a distributed RTU concept that can provide the following features:  \n• Significant reduction of harness in large spacecraft systems  \n• Functional segregation at satellite level  \n• Increased satellite integration efficiency  \nThe selected configuration can adapt to any bus voltage between 20V and 100V. Dual MIL-STD-1553 RTI provides access to functional commanding, measurement reading and housekeeping telemetry of all important parameters. Optionally, CAN Bus can be implemented in the RTU concept on customer request.  \nFull redundancy can be obtained by a dual set of modules, either build in one unit integrated into the same backplane module or build as two separate units that can be operated in cold or hot redundancy.  \nTo optimize failure robustness and functional segregation, each module provides to the extent possible an autonomous function itself that shares only a few transparent interfaces distributed along the integrated modules via a backplane module.  \nTechnology  \nTerma has developed a unique implementation technology that provides superior cost, mass, and volume versus performance ratio for remote terminal units compared to competitors. Each module has its own mechanical structure that ensures sufficient unit mechanical strength when integrated, to sustain the mission mechanical load profile. A direct module thermal contact area to satellite structure ensures thermal segregation and proper temperature balance in the unit during all electrical load combinations.  \nThe concept provides a great flexibility during spacecraft integration, that allows to add, remove, or replace modules without unit dismounting during integration phase. High ESD tolerance on all external interfaces (>4 kV) ensures robustness to the integration phase.  \nModule functions  \nTo cover the need of interfaces for commanding, measuring and other interaction functions, Terma has developed a variety of module functions targeted to classical satellite needs. New module functions can be added if non existing specific interface functions are needed.  \nBackground  \nTerma has participated in European space missions for more than four decades and has pioneered several power system electronics technology and mission specific electronics developments. Based on these technologies and competences Terma has, in close corporation with satellite integrator OHB System, developed a new generation of Remote Terminal Units (RTU) applied in ESA missions and military satellites:  \nMission Launch Equipment Features Status  \n\n| Classified | 2023 | 2 x 3 x RTU | 28V MB, 1553, AC, HPC, OC, SDI, TA, VD | Flying in-orbit |\n| --- | --- | --- | --- | --- |\n| H2SAT | 2023 | 1 x 9 x RTU | 50V MB, 1553, AC, HPC, OC, TA, TSW, VD | Flying in-orbit |\n| Electra | 202? | 1 x 10 x RTU | 100V MB, 1553, HPC, TA, TSW, VD | Delivered for integration |\n| NAOS | 2024 | 1 x 2 x RTU | 28V MB, 1553, AC, HPC, OC, TA, VD | Delivered for integration |\n| Classified | 2025 | 3 x 2 x RTU | 28V MB, 1553, AC, HPC, OC, SDI, TA, VD | Delivered for integration |\n| HERA | 2024 | 1 x 2 x RTU | 28V MB, 1553, AC, HPC, OC, TA, VD | Flying in-orbit |\n| CO2M | 2025 | 2 x 3 x RTU | 28V MB, 1553, AC, HPC, OC, SDI, TA, VD | Delivered for integration |\n| Comet-I | 2029 | 1 x 2 x RTU | 28V MB, 1553, AC, HPC, OC, TA | In production |\n| ExoMars | 2028 | 1 x 4 x RTU | 28V MB, 1553, HPC, SDI, TA | In production |\n| Harmony | 2029 | 2 x 3 x RTU | 28V MB, 1553, AC, HPC, OC, S","cbCaimthJX962YJu","https://ap.wps.com/l/cbCaimthJX962YJu","pdf",1173352,"English","# Remote Terminal Units\n## RTU Function and Key Features\n## Technology\n## Module Functions\n## Background\n## Mission Launch Equipment Features and Status\n## Core Module and Interface Modules\n## Attitude Control Module (ACM)\n## Heater Distribution Module (HDM)\n## Orbit Control Module","[{\"question\":\"What interface and interaction functions do the remote terminal units provide?\",\"answer\":\"They provide interfaces for commanding, measurement reading, and housekeeping telemetry, covering classical satellite interaction needs.\"},{\"question\":\"How many functional modules can be combined in a customized RTU configuration?\",\"answer\":\"Customized RTUs can be composed into units comprising from three up to 16 modules.\"},{\"question\":\"What redundancy options are supported by the RTU concept?\",\"answer\":\"Full redundancy can be obtained by a dual set of modules, either integrated into one unit with the same backplane module or built as two separate units operating in cold or hot redundancy.\"}]","Remote Terminal Units - For All Types of Satellites | PDF",15]
