  • ★Stargaze koristi 10.000 Starlink satelita
  • ★30 milijuna mjerenja dnevno mijenja industriju
  • ★Besplatna usluga za operatere satelita

SpaceX je najavio Stargaze, novi servis za svemirsku situacijsku svijest (SSA) koji koristi podatke sa zvjezdanih trakera na gotovo 10.000 Starlink satelita u niskoj Zemljinoj orbiti. Svaki od tih satelita može generirati tisuće opažanja dnevno, što rezultira impresivnih 30 milijuna mjerenja objekata u svemiru svakih 24 sata.

Ta brojka nadmašuje sve postojeće komercijalne SSA sustave, koji se oslanjaju na tek nekoliko desetaka senzora na Zemlji ili u svemiru. Stargaze neće biti plaćena usluga.

Prema najavi SpaceX-a, podaci će biti dostupni drugim operatorima satelita besplatno, što stvara potpuno novi dinamički model u industriji. U okviru tradicionalnih SSA tvrtki poput LeoLabs ili ExoAnalytic Solutions, gdje se podaci prodaju po visokim cijenama, SpaceX-ov pristup mogao bi biti disruptivan.

Tehnička osnova Stargaze-a leži u zvjezdanim trakerima, kamerama koje su izvorno dizajnirane za navigaciju satelita praćenjem zvijezda. SpaceX je otkrio da ti senzori mogu detektirati i druge objekte u orbiti, uključujući satelite i svemirski otpad.

To otvara mogućnost praćenja desetinama tisuća objekata koji su trenutno teško uočljivi zemaljskim sustavima.

Međutim, kvaliteta podataka ostaje ključno pitanje. Zvjezdani trakeri nisu optimizirani za precizno praćenje objekata, za razliku od namenskih SSA senzora koji koriste radare ili optičke teleskope visokog razlučivanja.

Stručnjaci iz SSA zajednice ističu da su rane procjene učinkovitosti Stargaze-a ohrabrujuće, ali da je prerano donositi zaključke o pouzdanosti mjerenja. Osim tehničkih izazova, Stargaze ima potencijal da promijeni ekonomiju svemirske sigurnosti.

Ako se pokaže da su podaci dovoljno točni, tvrtke koje nude plaćene SSA usluge mogle bi biti prisiljene prilagoditi svoje modele poslovanja. SpaceX već ima prednost u broju senzora, a besplatnim pristupom podacima dodatno jača svoju poziciju na tržištu.

Za operatere satelita, ovo bi mogao biti značajan napredak. Trenutni SSA sustavi često pružaju samo nekoliko opažanja dnevno, dok Stargaze nudi kontinuirano praćenje.

To bi moglo smanjiti rizik od sudara i poboljšati upravljanje orbitalnim resursima, posebno u sve gušćim orbitalnim regijama poput LEO-a.

Ipak, industrijski igrači oprezno reagiraju. Neki ističu da će kvaliteta podataka biti odlučujuća, dok drugi upozoravaju na monopolističke tendencije SpaceX-a. Kako god bilo, Stargaze je korak koji bi mogao definirati budućnost SSA industrije. Ovo je samo početak nove ere u praćenju svemirskog otpada.
