Satellite imagery and radio frequency data from Sfera Technologies
Sfera Technologies sells imagery and data from commercial satellite operators. Its catalogue lists 24 satellite systems with six sensor types. 59 satellites in these systems are available for new acquisitions over a chosen area (tasking). Three optical systems are offered as archive imagery only. 16 of the 24 systems are available via API. The table lists typical applications for each data type.
| Data type | Typical use | Systems | Resolution |
|---|---|---|---|
| Optical (multispectral) | Crop health, urban development, object counting, change detection | 15 systems, listed below the table | 0.3 m to 4.75 m in black and white (panchromatic); the colour bands are coarser |
| SAR (radar) | Imaging at night and through cloud, defence and OSINT, urban development | Acadia (Capella Space), PAZ, KOMPSAT-5 and OSE Hawkview, all X-band | 0.25 m to 40 m, depending on the system and imaging mode |
| Thermal | Heat sources: industrial activity, gas flares, urban heat, wildfires, soil temperature | HOTSAT (SatVu), mid-wave infrared; Hydra, long-wave infrared | HOTSAT 3.5 m; Hydra 30 m or 100 m |
| Hyperspectral | Telling plant species, soils and materials apart | Dragonette (Wyvern), 31 spectral bands; OSE-HS01/02 | Dragonette 5.3 m; OSE-HS01/02 5 m |
| Radio frequency (RF) | Locating radio emitters, such as ships that do not report their position | BRO, X-band, tasking only | No pixel resolution; geolocation accuracy is not published |
Optical systems for tasking and archive: Beijing-3N, Beijing-3A/C, Superview Neo-1, Superview Neo-3, OSE-GF01, THEOS-2, GÖKTÜRK-1A, KOMPSAT-3A, KOMPSAT-3, OL-1, Wuhan-1 and BlueBon. Optical systems as archive only: TripleSat, KOMPSAT-2 and Superview-1. Stereo and tri-stereo acquisitions are available from Beijing-3N and Beijing-3A/C.
SAR Stripmap images from Capella Space can be tasked directly on app.sfera.earth and via API. The Wyvern archive on app.sfera.earth holds more than 2,500 images. SatVu archive data can be ordered by email. Portfolio as of the Sfera Technologies satellite data catalogue, October 2026.

Alternatively, you may request an API key to search the archive or task satellites directly. Some data can be ordered online through the platform: SAR Stripmap tasking and the Wyvern hyperspectral archive are on app.sfera.earth. If you are not sure which data fits your project, you can book a free consultation.
Sfera Technologies ground station network
Sfera Technologies sells access to the Sfera Network, a network of satellite ground stations for satellites in low Earth orbit. Satellite operators use it as their main ground station network, or to add contact time to their own antennas. The network supports uplink and downlink. Satellite passes (contacts) are booked per minute through a REST API. Only the minutes used are invoiced.
The frequency bands vary by site. The website lists UHF, VHF, S-band and X-band for Moravia. It lists UHF and S-band for Quito. For the other active sites it lists S-band and X-band.
| Status | Sites |
|---|---|
| Active (12) | Moravia (Czech Republic), Muonio (Finland), Dublin (Ireland), Stockholm (Sweden), Baku (Azerbaijan), Bahrain, Seoul (South Korea), Mingenew (Australia), Cape Town (South Africa), Quito (Ecuador), Columbus (USA), Seattle (USA) |
| Planned additions (7) | Tampere (Finland), Sofia (Bulgaria), Singapore, Punta Arenas (Chile), Kinshasa (DR Congo), Yellowknife (Canada), Reykjavik (Iceland) |
Service types and the setup process are on the ground stations page. Sites as of October 2026.
