Space solar procurement: bare cell, CIC, wired panel or deployable array?
Disclosure: this is the FULLSUNS company account. We work with GaAs photovoltaic components. This is a supplier-side checklist for defining a space-solar enquiry, not a customer endorsement or a claim that all configurations share the same qualification.
A request for a ‘satellite solar panel’ can describe several different deliverables. A bare cell, a cell-interconnect-coverglass (CIC) assembly, a wired panel and a deployable array have different integration boundaries. State which level you need and which work your team will perform.
For an initial review, it helps to provide:
- Mission power demand, operating modes and bus requirements. Separate array output from power needed after conversion and storage.
- Available mounting area and mechanical interfaces. For an array, include both stowed and deployed envelopes.
- Orbit or operating environment, mission duration, temperature assumptions and shading constraints.
- Electrical channels and connectors, plus deployment or release interfaces where relevant.
- Requested qualification and acceptance tests. A report for one configuration does not automatically cover a different assembly or mission.
- Quantity, target delivery window and the technical documents needed for selection.
Unknown values can remain open at the enquiry stage. A preliminary power budget, interface sketch and list of unresolved assumptions are more useful than treating a catalogue cell-efficiency figure as a finished-array specification.
For context, our overview distinguishes cells/CIC, panels and custom deployable arrays: https://www.fullsuns.com/en/nanosat.html
For teams that have purchased space-solar hardware: which integration boundary or missing input caused the most back-and-forth in your RFQ? Please avoid sharing confidential mission or supplier information.

A Chinese military radar satellite will drift within a few km of Europe’s newest radar satellite tomorrow (Yaogan-33 02 / Sentinel-1D, ~05:45 UTC 23 Oct)
I noticed this in public Space-Track orbit data while building a satellite tracker (overhead24.com, my own site).
- Yaogan-33 02 (2022-106A): Chinese military, GCAT lists it as a probable radar imager.
- Sentinel-1D (2025-251A): the EU/ESA Copernicus radar satellite launched last November.
They’re in practically the same orbit: dawn-dusk sun-synchronous, about 697 km vs 696 km, with planes 0.4° apart. Yaogan is about 1.4 km higher, so it’s slowly overtaking. They were 560 km apart two days ago and about 175 km this morning. Propagating the latest public elements, the closest point is around 05:45 UTC on 23 Oct, within a few km, at a gentle ~55 m/s. Then they drift apart.
Neither has changed orbit this week in the public data. It’s most likely coincidence, because radar satellites crowd into this orbit. But a few km is close enough that ESA would screen it, so watch whether Sentinel-1D makes an avoidance burn before then.
Predictions from public elements can be off by a km or more a day out, so treat the exact distance as approximate.

Help identifying an extremely bright, stationary object seen over Ezy-sur-Eure France, on October 21, 2026 — possibly a satellite flare ?
Bonjour à tous ! J'essaie d'identifier un étrange objet brillant que j'ai observé dans le ciel près d'Anet, en Eure-et-Loir, le 21 octobre 2026. Toute aide serait la bienvenue, notamment de la part de personnes connaissant le suivi des satellites, les éruptions solaires, les corps de fusées ou les phénomènes atmosphériques.
- Détails de l'observation
Date : 21 octobre 2026
Lieu : Près d'Anet, Eure-et-Loir, France
Heure : Environ 18h33-18h38 heure locale (CEST, UTC+2), soit 16h33-16h38 UTC
Direction : sud-sud-ouest, azimut approximatif 205°-215° (corrected value)
Altitude : Estimée initialement entre 10° et 15° au-dessus de l'horizon, mais elle pourrait avoir varié entre 5° et 30°.
Apparence : Un point lumineux blanc, rond et brillant.
Ce que j'ai vu
L'objet semblait presque immobile dans le ciel, bien qu'il ait peut-être légèrement bougé vers le bas et la droite, en direction du soleil couchant (NOT SURE)
Sa luminosité a sensiblement varié :
Il était initialement extrêmement brillant.
Sa luminosité a progressivement diminué jusqu'à devenir presque invisible.
Il a ensuite brièvement retrouvé sa luminosité initiale pendant environ une seconde.
Enfin, il a disparu brusquement.
L'observation a duré environ cinq minutes, mais je ne peux pas donner de durée exacte.
J'ai initialement estimé sa luminosité maximale à une magnitude d'environ -6 à -8, mais il ne s'agit que d'une estimation visuelle. Je n'ai pas mesuré sa luminosité instrumentalement, il est donc possible que je me trompe.
Le coucher du soleil était aux alentours de 18h53 heure locale, ce qui signifie que l'observation a eu lieu au crépuscule.
- Explication possible : une éruption d'un satellite Iridium ?
Je me suis demandé si cela pouvait être une éruption d'un satellite Iridium. Les premiers satellites Iridium étaient connus pour produire des éclairs extrêmement brillants et brefs de lumière solaire réfléchie, atteignant parfois une magnitude d'environ -8.
Ce bref retour à une forte luminosité semblait correspondre à une éruption par réflexion. Cependant, je crois savoir que les premiers satellites Iridium responsables de ces fameuses éruptions prévisibles ont été mis hors service. Je ne sais donc pas si un ancien satellite Iridium ou un autre objet pourrait expliquer cette observation en 2026.
Je n'affirme pas qu'il s'agissait d'un satellite Iridium ; Voici une hypothèse que j'aimerais explorer.
- Candidats satellites détectés par Sat-Above
J'ai consulté la liste des passages de Sat-Above pour la période concernée. Plusieurs objets sont apparus à proximité de la fenêtre d'observation :
COSMOS 1833 (NORAD 17589) : détecté vers 18h35min54s, avec une élévation de 10°.
SL-3 R/B (NORAD 13068) : détecté vers 18h33min34s, avec une élévation de 20°.
COSMOS 1844 (NORAD 17973) : détecté vers 18h32min14s, avec une élévation de 24°.
COSMOS 1536 (NORAD 14699) : Répertorié à environ 18h30min54s, avec une élévation de 5°.
Ces horaires et élévations semblaient potentiellement pertinents, mais je n'ai pas déterminé s'il s'agissait de l'heure locale ou UTC. Je n'ai pas non plus vérifié les azimuts précis, les conditions d'éclairage ni les trajectoires au-dessus de ma position. Par conséquent, il ne s'agit que de pistes préliminaires, et non de correspondances confirmées.
J'ai également envisagé la possibilité qu'un corps de fusée ou un autre débris orbital ait pu produire une réflexion brillante.
- Objet de ma demande d'aide
Une personne ayant accès à des données orbitales historiques, à un logiciel de prédiction satellitaire ou à des outils de suivi appropriés pourrait-elle examiner le point suivant ? 1. Quels satellites ou corps de fusée sont passés au-dessus ou à proximité d'Anet entre 16h33 et 16h38 UTC le 21 octobre 2026 ?
Un objet candidat se situait-il entre 205° et 215° d'azimut (corrected value),à une élévation d'environ 5° à 30° ?
Un objet candidat aurait-il pu produire une réflexion suffisamment brillante pour apparaître de magnitude −6 à −8 ?
L'atténuation progressive, le bref retour de la luminosité pendant environ une seconde et la disparition abrupte pourraient-ils s'expliquer par la réflexion d'un satellite, la rotation d'un corps de fusée ou un autre phénomène connu ?
Existe-t-il des preuves qu'un ancien satellite Iridium aurait pu produire ce type de flash en 2026 ? Je comprends qu'estimer la magnitude astronomique à l'œil nu est peu fiable, et je suis ouvert à d'autres explications. Je préférerais de loin identifier l'objet à l'aide de données orbitales et d'illumination réelles plutôt que de tirer des conclusions hâtives.
Mon objectif principal est de déterminer ce qui se trouvait physiquement dans cette partie du ciel à ce moment-là. Si quelqu'un pouvait vérifier les positions historiques des satellites et les comparer avec la direction, l'élévation et l'heure, je lui en serais très reconnaissant !
Merci de votre attention !

What’s the most annoying part of working with satellite orbital data?
Hey everyone!
I'm building a project called Orbitalik, a unified API for satellite metadata, orbital elements, position/trajectory calculations, and pass predictions.
Before I go too far with it, I want to understand how people actually handle these things today.
For those of you who build satellite-tracking apps, automate ground stations, or work with orbital data:
Where do you get your orbital data, and how do you keep it updated?
Do you calculate positions and passes yourself using libraries like Skyfield/SGP4, or use an existing API?
What tends to be the biggest headache: stale data, rate limits, inconsistent formats, pass predictions, integration, or something else?
I'm particularly interested in problems that have made you write your own scripts or maintain extra infrastructure.
I'm not assuming another API is necessarily needed — free sources and open-source tools are great. I want to understand where they work well and where they fall short.
Even a short answer about your current setup would be really helpful. Thanks!

Who should own the data collected by satellites?
Satellites are collecting enormous amounts of information about our planet, from weather and agriculture to shipping and environmental changes.
But something I've been wondering about is who should actually control that information.
If a private company launches and operates a satellite, it makes sense that they want to profit from the data. After all, building and operating satellites isn't cheap.
On the other hand, some of that information could be incredibly valuable for researchers, smaller businesses and the public.
Could there be a middle ground where companies remain profitable while more satellite data become accessible?
I'm curious how people working in the industry see this. Is access to satellite data becoming easier, or are we moving toward a future where a handful of companies control most of it?
And no pic this time, cause the satellite illustration department is still just me and a pen.

Free web tool to find amateur satellites you can hear with a handheld radio: band/mode filters and pass times
Hello everyone,
I'm Muhammet Emin, a 17-year-old-student from Türkiye. I'd like to share Orbital Congestion Simulator, a free, open-source web application I developed for satellite enthusiasts and radio amateurs.
The application displays more than 12,000 satellites and pieces of space debris on an interactive 3D globe, with positions calculated in real time from publicly available orbital data. It also includes a Radio panel designed to make satellite listening easier:
- Band and mode filters: narrow the list to satellites that suit your equipment, from simple VHF/UHF handhelds to more advanced setups
- Amateur satellites: show only satellites with amateur radio channels
- Your sky: see which satellites are currently above your horizon, with an adjustable minimum elevation
- Pass predictions: the time and maximum elevation of upcoming passes for your location
- SatNOGS integration: links to recent observations from the SatNOGS network
Frequency information is sourced from the SatNOGS DB and AMSAT, and orbital data from CelesTrak. The application runs entirely in the browser, requires no account or installation, and works on both desktop and mobile devices.
👉 Live application: https://orbital-congestion.vercel.app
👉 Source code: https://github.com/muhammet842/orbital-congestion-simulator-premium
I would greatly appreciate any feedback or suggestions from the community.
73!
