Ground Station as a Service

Every antenna you own, run as one network.

Plan passes across all your stations, track and record at each antenna, and deliver data to every customer under their own account. Antenna time you do not use becomes time you can sell.

Cost

Add a module, not a rack unit.

Today a station is built antenna by antenna. Each dish or Yagi feeds its own rack of modems and receivers, the most expensive equipment in the station, and every unit carries its own paid licences. Operators set the equipment up for each pass by hand.

€107,000one S-band TT&C modem, per antenna

$2,387a USRP B210 software-defined radio, for the receive side

It doesn't have to be like this.

With TytoSpace each antenna needs only a software-defined radio and a small edge node. One GPU server processes every antenna, passes are planned and run automatically, and a new mission is a software module, not a licence upgrade.

Maintenance assumed at $15k to $30k a year for each of the two large units, from NASA maintenance renewals for a receive system. Ettus list prices; GPU server estimated from component list prices. The X410 gives X-band headroom; a 15 Msym/s link like NOAA-20, which TytoSpace decodes, runs on a B210. Receive side only: the TT&C modems also transmit and range, which is left out here, and the TytoSpace licence and the small edge computer beside each SDR are not included.

Plan, AI-powered

Every pass is planned before it rises.

TytoSpace Plan computes every pass over every antenna from current orbital elements, gives each one a quality score and books the antenna, the band and the processing in one step. Two bookings can never hold the same antenna, and the plan is sent to each edge node as a signed bundle, so a station keeps working offline.

When something changes, the plan is rebuilt and pushed to the edge. For larger networks, a learned planner, delivered per project, predicts which contacts will deliver data from orbit geometry, weather and space weather.

Pass detail

Open any pass before you book it.

Each pass shows its track across the sky, elevation, azimuth and Doppler over time, and every transmitter the satellite carries, with the ones that have a ready decoder marked.

Pass detail for the ISS in the TytoSpace console: upcoming passes over Piotrowo, the ground track on a map, elevation over the pass and the sky plot. — The ISS over Piotrowo on UHF, 7 November 2026, in the TytoSpace console: 14 upcoming passes, the ground track, and the elevation and sky plot of the selected pass.

More data

Two chances at every pass.

A standard decoder catches what it can while the satellite is overhead. TytoSpace keeps the raw recording and decodes it a second time, with methods a real-time receiver cannot afford.

266 archived recordings, two decoders

	Standard decoders	TytoSpace
CANVAS, FSK 9600	4,066 packetsDire Wolf and gr-satellites	6,220 packets53% more

Unique packets that pass their CRC, on 266 archived CANVAS recordings. The two passes drawn beside it: one CELESTA recording from the SatNOGS network (observation 6284801), where every TytoSpace frame passes CRC-16/X.25 and the 3 reference frames are among the 20, and one public Meteor-M2-2 recording, where every SatDump frame is retained. Beacon values are in engineering units, the time axis is the analysis window, and the IQ trace is drawn for illustration. Methods: timing and phase hypotheses on overlapping windows, a channel model learned from validated frames with a Viterbi sequence detector, soft-list decoding; a frame counts only when its own CRC passes. The limits of each result are on the Results page.

Modules

Build the chain you need.

Every stage of the receive chain is a module, and each one runs on the cheapest hardware that can do it. Ready-made modules cover 642 satellite profiles, so a mission on the list starts from a ready profile instead of new code. Your own module plugs in at any tier: on the FPGA, on the GPU or on the CPU.

Module list

Every module, listed and self-tested.

The console lists each demodulator and decoder module with its stage, the modulations it covers, the satellite profiles it serves and the result of its self-test.

Module list in the TytoSpace console: channelizer and demodulator modules for FSK, PSK, CPM, CW, DVB-S2, LoRa and SSTV, each with its stage, modulations, served profiles and a passed self-test. — The module list in the TytoSpace console, November 2026.

Identification

Unknown signal? TytoSpace works it out.

A traditional receiver is configured for the signal it expects. TytoSpace starts from the spectrum: it finds every carrier in the band, tests modulation, symbol rate and coding for each one in parallel, and names a signal only when it yields valid frames. That is how it locked onto PROBA-2 on 25 October 2026 without a prepared profile.

Inspect

See what went wrong, not just that it did.

Zoom into any stretch of the pass. The lab marks gaps, clipping, gain steps and spurs, traces the measured carrier, and explains each finding in plain words.

The marks along the right edge are the 103 decoded frames.

Frames

Every frame, down to the bit.

Decoded frames open as a packet view: a list with the CRC status of every frame, a tree of every field, and the hex, linked both ways and coloured by field.

CRC status for each frame: valid, repaired or doubtful
Pick a field to light up its bytes, or a byte to find its field

The source address is selected in the tree, and its bytes are outlined in the hex view.

Traffic

Benchmarks

Measured on the same samples.

Each comparison gives TytoSpace and the reference receiver identical input. A frame counts only when it passes its CRC or Reed-Solomon check. Every number below comes with its sample size and its limits.

958,134

X-band frames, one NOAA-20 pass

On the NOAA-20 pass of 25 October 2026, 11:26 UTC, received on the shared 4.5 m dish near Poznań, TytoSpace confirmed the link from the samples, QPSK at 15 Msym/s with convolutional and Reed-Solomon coding, and decoded 958,134 frames that pass their Reed-Solomon check. The NOAA-20 images on this site come from this pass.

One pass, decoded from the stored recording after the pass, not live. The count covers every virtual channel, 177,668 idle fill frames included. No frames between about 226 and 354 s of the recording, where the signal was weak.

+53%

Valid packets, 266 recordings

On 266 archived CANVAS recordings (FSK 9600), TytoSpace recovered 6,220 unique CRC-checked packets. Dire Wolf and gr-satellites together recovered 4,066. TytoSpace found at least one extra packet in 141 of the 266 recordings.

One mission, and a cohort we also used during development. TytoSpace uses much more compute than the reference receivers and missed 4 packets they found.

+16%

Image frames, Meteor-M2-2

On one public Meteor-M2-2 recording, TytoSpace decoded 3,700 frames where SatDump 1.2.2 decoded 3,198. Every SatDump frame is also in the TytoSpace output. Most of the extra frames come from the start of the pass, before SatDump produces its first output.

Meteor-M2-2 channel 1 decoded by SatDump: the first part of the pass is missing and shows as black.

One public recording from the SatNOGS network, not received by our station.

5.1 to 5.8 s

Unknown signal to first frame

With nothing configured for the satellite, TytoSpace identified the signal and handed it to a live decoder. On ALOS-4 and CHEOPS the first valid frame arrived 5.1 to 5.8 s after the signal appeared.

S-band recordings replayed in real time, not live passes.

86 to 240

SSTV image lines, ISS

From our own UHF receptions at Piotrowo, a single receiver had produced one fragment of 86 of 240 lines. TytoSpace's SSTV decoder corrected Doppler from the orbit and combined several receptions line by line, recovering complete slides.
