Bridge the entire analog and digital boundary with our economical, scalable, unified space communications system. <\/strong>The Mission Link Modem High Rate (MLM-HR) represents the next generation of integrated solutions for ground systems. <\/p>\n\n\n\n The MLM is a space communications system that combines a proven software framework with state-of-the-art digital signal processing components to deliver a full range of user-configurable, uplink and downlink RF-to-IP transmission and data processing capabilities.<\/p>\n\n\n\n The MLM-HR utilizes the infrastructure and capabilities of the L\/S-Band MLM to implement a high-rate solution. The MLM-HR receives satellite IF transmission in a 720 MHz, 1.2GHzor 2.4 GHz signal. The MLM-HR demodulates and extracts the telemetry data from an IF signal. The Test Modulation Uplink allows the system to perform loopback testing to ensure data reliability and error correction decoding are operating within defined parameters. MLM provides a VITA-49 Radio Transport (VRT) network interface.<\/p>\n\n\n\n The frame synchronization subsystem processes extracted telemetry baseband data from the downlink signal. It performs frame synchronization and de-randomization utilizing the RS Forward Error Correction (FEC) decoding and correction for ensuring reliable delivery of data. The system makes a data quality determination and provides the relevant RS Flags to the system to request retransmission of data packets. The CCSDS VC Processor filters the data by Virtual Channel (VC) and Application ID (APID) unique to each spacecraft. The APID processing also has a reporting capability to provide operational statistics on total frames received, total uncorrectable frames, and VCID and APID frame and packet counts. <\/p>\n\n\n\n The MLM\u2019s flexibility allows for local or remote control from a highly flexible graphical user interface including, a full-featured remote interface API for remote control, scripting, and automation.<\/p><\/div>\n\n\n\n The MLM-HR is fully user-configurable to send real-time telemetry acting as a TCP\/IP server or client. Data can be selected by VC Data Unit (VCDU) for each port or connection. The MLM-HR also provide data playback by VC sending selected VCDUs to each client. <\/p>\n\n\n\n Based on a robust, enterprise-grade server architecture to provide component-level redundancy and continuous operational reliability, the MLM system is highly scalable and can be expanded to include additional interfaces and increased storage capacity.<\/p>\n\n\n\nWhat Is The Mission Link Modem (MLM) And How Does It Work?<\/h3>\n\n\n\n
