The Curious Case of the Rogue 'SpaceBee' Satellites - The Atlantic,May 2018
"The SpaceBee is a prototype satellite from Swarm Technologies, a start-up founded in 2016 and based in Los Altos, California. There is little publicly available information about Swarm. According to Mark Harris, the reporter at IEEE Spectrum who first broke the story about the satellites’ unauthorized launch, the company is in stealth mode"

"As of April, there are 589 nanosatellites in orbit—satellites with masses between one kilogram and 10 kilograms (2.2 pounds to 22 pounds), according to a comprehensive database run by Erik Kulu, a spacecraft systems engineer in Glasgow"

"Lockheed Martin is currently building a radar system that would allow the Space Surveillance Network to track smaller objects than is possible now. The program is expected to be finished by the end of this year. "

NanoRacks to Launch 15 Cubesats for Nationwide Canadian Project - Via Satellite - April 2018
"April 18 launch of two South African-built nanosatellites onboard a United Launch Alliance (ULA) rocket from Cape Canaveral, Florida. NSight 1, designed and manufactured by Cape Town-based SCS Space, a member of the SCS Aerospace Group, and ZA-Aerosat, designed and manufactured by CubeSpace of the Stellenbosch University, will launch as part of a batch totaling 28 nanosatellites from 23 different countries."

"The satellites are part of the QB50 project funded by the European Union and managed by the von Karman Institute to conduct research in the lower thermosphere between 200km to 380km altitude. "

The FCC’s Big Problem with Small Satellites - IEEE Spectrum Apr 2018
"The FCC was worried about collisions in space, where even the smallest objects traveling at orbital velocities can inflict massive damage on satellites or, in a worst-case scenario, manned spacecraft. It thought Swarm’s SpaceBees satellites, measuring 10 by 10 by 2.5 cm, would be just too small to track."

"An investigation by IEEE Spectrum has revealed that the FCC licensed multiple satellites smaller than 10 cm over the past five years, including some as small as 3.5 by 3.5 by 0.2 cm. But the commission has also changed its mind from one application to the next, refusing launch permission for satellites that were virtually identical to ones previously authorized. This uncertainty has led to at least one satellite maker exporting his technology rather than risk being denied a license in the U.S."

"Launching a kilogram payload to low earth orbit (LEO) currently costs at least $3000. "

"Eventually, NASA adopted KickSat-2 as an official NASA mission. Due to a regulatory quirk, NASA’s own satellites are overseen by the National Telecommunications and Information Administration (NTIA) rather than the FCC. KickSat-2 is now slated for launch late this year or early next. "

"Last summer, the London-based Breakthrough launched six Sprites on a German satellite from an Indian launch vehicle, far outside the FCC’s jurisdiction. Germany has no minimum size regulations for satellites."

Satellite entrepreneurs looking for sky-high revenues from internet services in space | Financial Post, Feb 2018
Jeff Foust: "Kepler Communications, a Toronto company planning a constellation of 50 small satellites to provide communications for Internet of Things applications, launched its first satellite last month on a Chinese rocket. As a Canadian company, it faces fewer restrictions on its choice of launch vehicles than U.S. companies, one Canadian entrepreneur noted, allowing it to take advantage of low-cost Chinese launches."

"Another contributor to fast iteration is launch availability. That’s an area in which Canadian companies have an advantage, Slifierz says. “Kepler benefits from being a Canadian company because there are a lot fewer restrictions on where we can launch vehicles from. They were able to use a Chinese rocket. That would not have been possible (if it were a U.S. company).”"

Largest cubesat operators say 25-year deorbit guideline a priority - Feb 2018
Planet and Spire, operators of the two largest commercial cubesat constellations in orbit, say they manage their fleets to prevent retired spacecraft from lingering in space beyond internationally accepted guidelines.


Safyan suggested that the problem of smallsats-turned-space-debris in LEO will likely “be a self-correcting problem” as the launch industry brings to market vehicles and adaptors specialized for such spacecraft.

Speaking at the SmallSat Symposium here Feb. 7, officials from Planet and Spire said the companies have self-imposed rules to ensure their satellites burn up in Earth’s atmosphere within 25 years of shutting down, as suggested by the Inter-Agency Space Debris Coordination (IADC) committee.

International ground stations tricky for smallsat operators to license -
Small satellite operators wanting to build ground stations in multiple nations to connect with their satellites are finding it complicated dealing with different sets of regulations.

Those regulations vary to the point that trying to establish a ground station in one country might create disagreements between different nations over how those stations are controlled, industry representatives said Feb. 6 at the SmallSat Symposium here.

For NOAA’s licensing office for remote sensing satellites, the increasing globalization of the space industry means more countries are starting to regulate the same sector.

“If you have ground stations in another country, that country then wants to take jurisdiction and regulate you, and those regulations can contradict the way that the United States regulates,” said Tahara Dawkins, director of NOAA’s Commercial Remote Sensing Regulatory Affairs Office. “That’s a problem. That’s something that we are facing now with many of our companies with just something as simple as ground stations.”

2018 Could Be a Revolutionary Year for Smallsats - Via Satellite -Via Satellite Jan 2018
"2017 was a banner year for the satellite industry in many respects. 2018 could prove to be even more momentous, as the smallsat megaconstellations that have been under development for years finally emerge — along with the dedicated smallsat launch vehicles that will serve them. In an interview with Via Satellite, Northern Sky Research (NSR) analyst Carolyn Belle laid out her expectations for the year ahead"

"Overall, 2017 was a “very good year” for smallsat launch rates, Belle said, with the industry orbiting 329 smallsats (between 1 and 500 kg) in total. This is the highest number launched in one year to date, easily outstripping the mere 130 orbited in 2016."

Demand for Geosynchronous Earth Orbit (GEO) satellites have plummeted in recent years, culminating in just nine orders in 2017. “That was a more significant decline than anything we’ve seen before,” Belle said. “That was the lowest number in more than a decade. Global capacity pricing continues to sink like an anchor, making operators very cautious about their investments, Belle said.”

Spire Global is expanding cubesat constellation to offer persistent global view -
"Spire Global, the San Francisco-based company that operates 48 GPS radio occultation cubesats, could provide a persistent view of about 97 percent of Earth with a constellation of 150 satellites"

"A constellation of 100 to 200 radio occultation satellites, which provide detailed observations of atmospheric temperature and moisture, could be used in conjunction with geostationary weather satellites like NOAA’s Geostationary Operational Environmental Satellite-16 to dramatically improve the accuracy and spatial resolution of global weather prediction models, MacDonald said."

"Spire also is expanding its ground network. The company has 27 ground stations operating and is pushing to increase that number to 50 because the added ground stations will allow the firm to provide customers with data no more than 30 minutes old"

"In addition to using its spacecraft for meteorology, Spire’s cubesats carry Automatic Dependent Surveillance-Broadcast (ADS-B) payloads for aircraft tracking and Automatic Identification System (AIS) payloads for maritime tracking. “We collect about 10 million ship reports a day,” MacDonald said."
