Integrated TM and TC Processing
Software Modem combining Telemetry receive and Telecommand transmit in one pipeline, with continuous and burst-mode operation.
Expedite
Software-defined TT&C modem for NewSpace missions
Expedite is a software TT&C modem that replaces dedicated ground hardware. You reconfigure it per mission, from CubeSats to deep-space probes, without touching the hardware. It is listed in NASA's 2026 State-of-the-Art Small Spacecraft Technology Report.
How Expedite is used.
Ideal Use Cases
Expedite is used by:
- SmallSat operators: ground communications for LEO missions on CubeSats and other small platforms.
- University and research missions: academic teams running space experiments, prototypes and testbeds.
- Ground Station as a Service (GSaaS): providers that need a modem they can run in the cloud and drive over an API.
- Short-timeline missions: demonstration missions that need a working ground link quickly.
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. Use whichever fits your 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 shows link state, antenna orientation and the global pass queue live. We designed it with operators running real missions, so what you need during a pass is on the screen without digging through menus.
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 in one console.
