Information : Telemetry Processing Systems
Marshall Space Flight Center’s (MSFC’s) Huntsville Operations Support Center (HOSC) manages and processes telemetry data for payloads such as real-time operations of the International Space Station (ISS). Payloads typically consist of multiple experiments. The HOSC receives Ku-band and S-band telemetry data through the NASA Integrated Services Network, and sends commands, data loads, and file uplink data for the ISS payloads to the Space Station Control Center (SSCC). In return, the SSCC sends command responses, downlink files, and planning data/procedures to the HOSC. MSFC’s support center can also distribute encapsulated packet data to other payload telemetry sites (e.g., international partners, telescience support centers, remote facilities).
The HOSC is comprised of four systems: Payload Planning System Provides a unique payload operations and integration architecture subsystem with software capabilities to automate payload planning and scheduling activities.
Payload Data Services System Acquires, distributes, and stores ISS data for other payload telemetry sites.
Enhanced HOSC System Performs on-command and real-time telemetry processing for prelaunch integration/checkout, simulations, training, and flight operations.
Enhanced Mission Communications System
By processing telemetry data, the HOSC enables users to operate and control ISS payloads and experiments. All users can access the support center’s capabilities via a workstation as well as voice, video, and data network services. Remote users can access the HOSC by logging on with a password through X-windows and web services.
