Portable Ground Station For SATCOM-on-the-move

NOMAD is a modern, digital solution replacing analog terrestrial SATCOM processing with portable ground station capability. NOMAD digitalizes wideband RF data at the system edge and virtualizes modem processing enabling flexible SATCOM operations. Digital architecture modernizes aging analog systems—operators access advanced processing and multi-constellation capability where legacy analog systems reach obsolescence.

NOMAD supports vehicle-mounted and semi-permanent installation form factors enabling deployment flexibility. Vehicle-mounted configuration enables SATCOM-on-the-move supporting mobile operations. Semi-permanent installation enables establishing ground stations at fixed locations. Flexible form factors enable deploying SATCOM capability matching operational requirements—operators select installation approach matching mission needs.

NOMAD performs high-speed digitization of wideband RF data at the system edge enabling processing modern satellite data rates. Legacy analog systems cannot efficiently digitize broadband RF limiting throughput. Digital digitization enables capturing full wideband signals—operators access complete signal information processing modern high-throughput SATCOM where analog systems limit bandwidth.

DIFI is an IEEE open standard for streaming digitized RF/IF samples and metadata over standard IP networks based on VITA 49.2 specification. DIFI standardizes how satellite ground stations share RF data enabling interoperability between different vendors and systems. Standard data format prevents vendor lock-in—operators share and process data across systems where proprietary formats create incompatibility.

NOMAD enables beyond-line-of-sight communications with LEO, MEO, and GEO constellations supporting multi-band, multi-constellation operations. Single-constellation platforms lock operators into one satellite network losing capability when access changes. Multi-constellation capability enables accessing diverse satellite systems—continuous operations where single-system platforms face service interruptions switching between networks.

NOMAD’s fully virtualized modems with advanced DSP enable flexible waveform processing and signal demodulation. Fixed modem hardware locks operators into single modulation schemes limiting signal processing options. Virtualized architecture enables switching modulation approaches and processing algorithms—operators adapt to different satellite networks and signal types where fixed modems limit flexibility.

NOMAD supports operations in denied, disrupted, intermittent, or low-bandwidth environments with portable form factors and hub-and-spoke BLOS data backhaul. Fixed terrestrial infrastructure cannot relocate to changing operational areas. Portable SATCOM capability enables forward deployments and dispersed operations—SATCOM-on-the-move supporting denied environment operations terrestrial systems cannot reach.

Hub-and-spoke architecture centralizes processing at a main ground station hub while remote sites connect via beyond-line-of-sight satellite backhaul. Traditional terrestrial networks require line-of-sight towers limiting coverage. Hub-and-spoke BLOS enables dispersed operations connecting remote locations through satellite—continuous network access where terrestrial infrastructure has coverage gaps.

NOMAD’s modular RF frontend with standard RF cabling enables mission-adaptable operations without hardware redesign. Fixed RF designs lock operators into single frequency bands preventing optimization for different satellite networks. Modular architecture enables adapting to different frequency requirements—operators configure RF matching mission needs where fixed designs prevent mission flexibility.

NOMAD supports military and commercial operators requiring portable, modern SATCOM ground stations. Military operators deploy NOMAD for field operations where terrestrial infrastructure is unavailable. Commercial operators leverage NOMAD for remote site connectivity and mobile SATCOM operations. Portable capability enables diverse missions where fixed ground stations cannot deploy.
