From Frustration
to First Contact
We stripped away the noise and kept what works. Ground communication should be straightforward, dependable, and ready when you need it most.
Overcoming Throughput & Precision Issues
As missions mature, the "bottleneck" shifts. It’s no longer just about talking to the satellite (S-Band); it’s about the massive amount of data coming back (X-Band). We address the two biggest technical hurdles: bandwidth limits and the extreme difficulty of tracking narrow X-Band beams.
Integrated Dual-Band Engineering
Instead of forcing you to synchronize two different antennas or complex third-party modems, we’ve built the S and X feeds into one "Plug & Play" unit. The addition of Monopulse Tracking is the "secret sauce"—it uses the signal itself to steer the dish, ensuring you never lose a drop of data.
Operational Mastery
The ultimate goal is peace of mind. By using a vertically integrated Groundcom station, you get a single interface (API/GUI) that handles everything from basic commands to heavy payload downloads. You save months of engineering time and get a professional-grade gateway that "just works."
Frequent questions
What frequency bands do your ground stations support?
Our systems are fully configurable for VHF (137-139MHz, 144-148MHz) and UHF (395-403 MHz, 430-450 MHz). You can choose a VHF-only, UHF-only, or a combined VHF+UHF configuration depending on your mission requirements.
Which modulations and protocols are supported?
Groundcom stations support a wide range of standard modulations including GMSK, AFSK, QPSK, BPSK, and FSK. We also support industry-standard protocols like AX25 and AX100 to ensure compatibility with most off-the-shelf satellite radios.
How accurate is the satellite tracking?
Our stations feature fully autonomous tracking based on public or custom TLEs. The system achieves a tracking accuracy of <1 degree with high-speed movement capability and a wide range of motion (-90° to +450° Azimuth; 0° to 180° Elevation).
Can I use my own data processing pipeline?
Absolutely. We designed our system to be flexible. You can choose to have the station process the entire signal and provide clean data content to your Mission Control, or you can receive raw IQ data directly for your own specific external processing.
Is it possible to integrate the station with my existing software?
Yes. While we provide a user-friendly Web-based GUI for manual control and real-time spectrum viewing, the entire system is also controllable via a powerful API interface for seamless integration into your automated workflows.
If You've Made It This Far, the Answer Is Yes
You're operating or planning a CubeSat or small satellite mission and you need ground infrastructure that won't become a multi-month project. The Groundcom VHF/UHF line was designed for exactly this profile.
