Integrated TM and TC Processing
Software Modem combining Telemetry receive and Telecommand transmit in one pipeline, with continuous and burst-mode operation.
Expedite
The Software-Defined Modem for the NewSpace Era
Featured in NASA's 2026 State-of-the-Art Small Spacecraft Technology Report, Expedite replaces rigid ground hardware with a reconfigurable software modem that adapts dynamically to every mission from CubeSats to deep-space probes. Built for performance, flexibility, and compatibility, Expedite helps satellite operators simplify ground operations, lower costs, and stay mission-ready at all times.
How Expedite is used.
Ideal Use Cases
Built for the new generation of space missions where adaptability and automation define success.
- SmallSat Operators: Efficient, reliable ground communications for LEO missions using CubeSats and small platforms.
- University & Research Missions: Easy-to-use modem for academic teams conducting space experiments, prototyping, or testbeds.
- Ground Station as a Service (GSaaS): Cloud-ready, API-driven modem for scalable Ground Station infrastructures.
- Agile Mission Deployments: Rapid setup for demonstration missions or short development timelines.
Engineered to integrate, not isolate.
Mission Scheduler
Pass planning with horizon up to 168 hours and ephemeris-driven automation across the full mission lifecycle.
Antenna Control Unit Support
Instrumentation and drive for supported ACUs; internal or external angle generation over TCP/IP or serial.
Doppler Pre-Compensation
Internal or external Doppler feed keeps the link locked through high-angular-velocity passes.
Half-Duplex RF Sequencer Control
Direct control packets for the Remos Sequencer and other external relay logic.
CCSDS-Compliant Stack
RS, CC, BCH, and short LDPC coding; CADU/CLTU framing; PLOP-1 and PLOP-2 procedures.
Host Integration APIs
TCP/IP, REST, WebSocket, ZeroMQ, and a web application — pick the integration model that fits the operator stack.
Mission Logging and Diagnostics
Telemetry, Doppler, antenna, IQ recording, BER/FER monitoring, TTC visualizer, and spectrum analyzer in one console.
Mission ops dashboard
Every link, every pass, on one screen.
The Expedite dashboard surfaces link state, antenna orientation, and the global pass queue in real time. Designed alongside operators running live missions — no submenus, no hunt-and-click. The signal is the UI.
Mission Control
Plan, queue, and prioritize missions across your entire satellite fleet.
Live mission ops
Real-time link state, Telemetry, and commanding the moment a pass opens.
Satellite tracking
Live AZ/EL pointing with mission elevation curves and doppler correction.
Full Ground Station control
Antenna, modem, sequencer, and scheduler — one console, every layer.
