How LeoStella uses software to track spacecraft hardware

TUKWILA, Wash. — LeoStella’s satellite tv for pc manufacturing unit has tons of hardware unfold out over 22,000 sq. toes of house, however the secret ingredient for its manufacturing course of might be the software program.

“What you see right here is the bodily format,” Brian Rider, LeoStella’s chief expertise officer, advised us throughout a tour of the satellite tv for pc enterprise’s headquarters in Tukwila, simply south of Seattle. “However what’s just a little bit more durable to see is the digital course of behind it.”

LeoStella, a three way partnership co-owned by BlackSky Holdings and Thales Alenia Space, depends on a workflow administration system that tracks satellite tv for pc parts throughout design and manufacturing. Workers use a digital dashboard to guarantee that each half is in its correct place on the correct time.

“It’s really not only a paperless course of, nevertheless it’s a digital, clever manufacturing strategy,” Rider defined. “We will report all of our manufacturing particulars. We will do statistical course of management and perceive the place we’ve got areas the place we will make our methods much less restrictive, or extra restrictive to enhance product high quality.”

The power itself is designed to maximise effectivity for turning out as much as 40 satellites per 12 months, together with two satellites monthly for BlackSky’s Earth-observation constellation. The inside of a standard-issue constructing in a suburban enterprise park was extensively reworked when LeoStella took over the house in 2018.

“Not many corporations have the prospect to take a step again and begin from a clear sheet of paper, and actually take into consideration all of the facets that make satellite tv for pc manufacturing attainable and environment friendly and inexpensive,” Rider mentioned. “That’s what we did at LeoStella.”

Two of the 120-pound (55-kilogram) satellites that LeoStella constructed for BlackSky had been misplaced per week in the past when a Rocket Lab launch failed, however extra are on the best way. One in every of BlackSky’s satellites was sitting on the manufacturing unit ground throughout our tour, able to be packed up and shipped to its launch location.

In the meantime, employees on the opposite aspect of the clear room had been testing considered one of Loft Orbital’s satellites, which is able to ultimately accommodate payloads from a number of prospects together with the Pentagon’s Protection Superior Analysis Tasks Company. Nonetheless different satellites had been in varied levels of meeting.

LeoStella can adapt its customary satellite tv for pc design to tackle a variety of orbital duties. Every satellite tv for pc sometimes consists of 4 decks, analogous to the decks of a ship. The propulsion deck is on the backside, with the avionics deck, the payload deck and the antenna deck layered on high of one another.

Every spacecraft is assembled on a dealing with fixture that may be wheeled right into a bay for ending up the connections and testing its built-in efficiency. There’s additionally a room-sized vibration chamber the place satellites may be rattled round on three axes to verify they will climate the stresses of launch and deployment.

Avionics software program will get checked out on “flat sat” workbenches which might be strewn with electronics. And in one other nook of the constructing, a thermal testing chamber can topic parts to tons of of levels of warmth, or chill them all the way down to the frosty situations they might face in house.

LeoStella’s job isn’t completed when the satellites are launched. As a result of it has such an in depth company relationship with BlackSky, the efficiency information from BlackSky’s satellites may be fed again to Tukwila for evaluation.

“We do an unlimited quantity of on-orbit validation, the place we take on-orbit conduct and take a look at information and correlate them to our predictions to guarantee that we’re appropriately modeling the efficiency and the conduct of the satellites,” Rider mentioned. “It’s all interconnected to that digital spine that we created.”

Rider mentioned LeoStella can fine-tune the manufacturing course of in midstream.

“We’ll construct a sure variety of satellites, and if there’s a chance to enhance the expertise — perhaps an enchancment within the provide chain, or new capabilities — we’re in a position to insert these into our manufacturing line in a strategic trend to consistently evolve that functionality,” he mentioned. “That additionally applies to our flight software program.”

Talking of evolution, LeoStella expects to evolve its capabilities as nicely. Rider mentioned the corporate’s workforce at present quantities to just a little greater than 40 staff — and most of them have been in a position to work remotely through the COVID-19 pandemic, due to the corporate’s digital platform.

Now LeoStella is waiting for new packages, together with the event of a third-generation BlackSky satellite tv for pc that’s anticipated to play a key position within the U.S. Military’s Tactical Geospatial Intelligence prototype program, or TACGEO.

“We’re planning to rent one other 5 – 6 by means of the top of this 12 months, and probably extra as our enterprise evolves,” Rider mentioned.

Sometime, a 22,000-square-foot satellite tv for pc manufacturing unit won’t be sufficiently big. However LeoStella has a plan for that.

“That’s a part of the explanation why we picked this industrial park right here,” Rider mentioned. “There are two massive buildings, and every constructing is just a little bit greater than 80,000 sq. toes. So there’s lots of alternative for us to scale.”
