For what SmallSats lack in size, they more than make up for in quantity and breadth of coverage, and that goes beyond just their physical dimensions. Along with unmanned aerial systems (UASs or drones), SmallSats (which have several related subsets such as cubesats, nanosats, microsats and others) seem to dominate headlines and conversations in Earth-observation industries and media.
The popularity is understandable, as SmallSats provide several key discussion points:
- They're interesting”SmallSats come in many different shapes and sizes, and some are so small (10 centimeters per side) to seem incapable of collecting and relaying useful data about Earth (but they can).
- They're accessible”Commercial SmallSats can cost a fraction of large satellites, and new companies are regularly emerging to try and raise capital to put their devices into space. And organizations such as NASA sponsor initiatives that allow universities, high schools and even elementary schools to build SmallSats that actually are placed into Earth orbit.
- They're a real market”Market-research company Euroconsult estimated in a 2015 report that the SmallSat market would reach $7.4 billion in five years. A report the company recently released in 2016 upped that estimate to $22 billion over the next 10 years.
SmallSats have a trajectory similar to UASs. Both have been around longer than people think”the first Small Satellite Conference, hosted by Utah State University, was held 30 years ago, and various governmental and private space companies have dabbled in smaller satellites for at least that long.
But the commercial explosion happened when the electronics, sensors and cameras required to make Earth observation useful became so small and cheap that they could be pieced together off the shelf into inexpensive devices. The aforementioned Euroconsult report, Prospects for the Small Satellite Market, estimates that 3,600 SmallSats will be launched in the next 10 years, and the market will grow by 76 percent over the previous decade's output.
Four companies plan to launch more than 1,400 satellites during this period alone: Planet [the recently shortened name of Planet Labs], Spire Global, BlackSky and Satellogic, notes Adam Keith, managing director of Euroconsult Canada and editor of the report. Â
All these satellites will need a means to get into space, leading to more growth in the launch-services market. Those who scoffed at private companies such as SpaceX getting into the rocket business are finding their skepticism unfounded, as launch companies currently have more customers than they can handle lining up to use their services.
And if you can get your SmallSat to the International Space Station, NanoRacks has deployed more than 100 cubesats into Earth orbit through its CubeSat Deployer via the JAXA KIBO airlock. Their customers include Planet, NanoAvionics, Spire, Southern Stars, NASA, Lithuanian Space Association, Kaunas University of Technology, MIT, Booz-Allen Hamilton, Planetary Resources, GOMspace, Aalborg University, University of Colorado and University of Michigan, among others.
Meetings and Groups
Although the first SmallSat event started 30 years ago (with kudos to Utah State for pioneering), the last couple years have seen several new events sprout up, hoping to take advantage of surging SmallSat popularity.
The inaugural 2016 SmallSat Symposium (smallsatshow.com) was sold out in Silicon Valley, which has become the hub for recent SmallSat development and investment, and the February 2017 event will return there. The Utah State event will be held in Logan, Utah, in August 2016 (smallsat.org), and the 2016 Canadian SmallSat Symposium was such a success that the 2017 version is already booked for fall 2017 in Toronto (smallsat.ca).
Many other organizations and universities have formed committees, groups or regular forums to keep tabs on the SmallSat revolution. For starters, NASA developed the Small Spacecraft Technology Program (which allowed the aforementioned universities and schools to get their vehicles into space), one of the nine programs in its Space Technology Mission Directorate, with three primary objectives: Â
- Identify and support the development of new subsystem technologies to enhance or expand the capabilities of small spacecraft.
- Support flight demonstrations of new technologies, capabilities and applications for small spacecraft.
- Use small spacecraft as platforms for testing and demonstrating technologies and capabilities that might have more general applications in larger-scale spacecraft and systems.
As an example in academia, the University of Georgia founded a SmallSat Research Laboratory in 2016 (smallsat.uga.edu), with plans to build its own cubesat (many universities have launched similar programs). And bridging public and private sectors, the U.S. Geospatial Foundation formed its Small Satellite Working Group in 2014 (for more information, see Building the SmallSat Community, below).
When discussing the future of SmallSats, it's difficult to avoid the obvious cliches: The sky is the limit, it's blasting off or even boldly going where no man has gone before want to type themselves. But in the case of SmallSats (and once again, UASs), the hyperbole likely is quite accurate.
SmallSats are one of the key ingredients in the NewSpace startup technology boom, which also includes the private space-launch companies such as SpaceX, private satellite communication companies (also making SmallSats, just for different purposes) and some interesting space-exploration companies making waves in equity-funding headlines. (Did you know that Planetary Resources is attracting heavy investment in its business model of asteroid mining? It's true!)
It seems that getting into space is the most-limiting factor for SmallSats. If that capability can be improved, look for several thousand more satellites to be launched in the coming decades. News reports and concerns of growing space junk are starting to trickle in, but, as of yet, scientists insist that the space around Earth is still massively open, and there is little concern for safety and investment for now.
As this is a rapidly evolving industry segment, the best bet for keeping up to date is at the Earth Imaging Journal Website (eijournal.com), starting with its SmallSat Company and Sensor Guide and refreshing its news feeds. The eyes in the skies are shrinking, and, as with most consumer technology, smaller can certainly be better.

USGIF Working Group Fosters Collaboration and Education
A paradigm shift is occurring in the commercial remote-sensing world as small satellites (SmallSats) mature to offer more agility, affordability and resiliency. The U.S. Geospatial Intelligence Foundation (USGIF), a nonprofit educational organization, is informing the GEOINT Community on the user needs for”and technical capabilities of”SmallSats and associated tasking, processing, exploitation and dissemination systems through its Small Satellite Working Group.
The USGIF Small Satellite Working Group has helped the government better understand emerging capabilities and helped systems developers gain a deeper appreciation of customer needs, says Rob Zitz, co-chair of the working group.
The working group meets on the fourth Wednesday of every month at USGIF headquarters in Herndon, Va., and helps with the planning of related USGIF events, including the Small Satellite Workshop the foundation hosted in November 2015 at the National Geospatial-Intelligence Agency (NGA) in Springfield, Va.
In May 2016, the Small Satellite Working Group hosted two panel discussions at USGIF's GEOINT 2016 Symposium in Orlando, Fla. The first, Filling the Gaps: Nuclear Activity and Small Satellites, discussed the role SmallSats play in answering intelligence questions concerning nuclear power. The second, Small Satellites and Open-Source Analytics: Technology and Tradecraft, was a conversation about how near-persistent commercial satellite data are coupling with open sources to provide decision makers timely, actionable information.
The working group leverages key conferences to spread the word about the new generation of small, low-cost and highly capable systems, notes Zitz.
