Non-GEO Constellations: Surviving the Disruption - Northern Sky Research - May 2018
"The main industry segments most affected by Non-GEO constellations are HTS Communications, IoT and Earth Observation (EO). Each of these segments presents its own set of challenges and therefore different barriers to success. NSR’s Satellite Constellations: A Critical Assessment report investigates for the first time what guarantees success for LEO constellations within these three segments and the associated disruption on the industry."

"higher revenue requires a higher market share, which further requires low latency and higher coverage. That is the main value proposition of mega-constellations. However, the bigger the constellation, the higher the capital investment needed, and the higher the complexity of manufacturing with (because of their architecture) higher replenishment cost."

"The new Non-GEO constellations are expected to cause the biggest disruption in the HTS segment, conspicuously in Consumer Broadband and Backhaul/Enterprise verticals."

"these new LPWAN IoT constellations, despite offering the highest innovative disruption value, are not likely to have a significant impact on the overall satellite industry - financially, contributing just over 2% of overall NGEO revenues by 2027."

"A combination of low revenues and insufficient market capture will restrain at least one EO constellation from closing its business case."

Satellite operators, data analysts agree on need for speed - SpaceNews.com April 2018
"Geospatial data companies are focusing intently on quickly acquiring satellite imagery and delivering it to customers."

Jeff Foust's gloss: "executives from several companies said they're developing larger networks of ground stations, and turning to advanced technologies like laser communications, to quickly get images from their spacecraft to the ground and then on to customers. The longer it takes to deliver images, they argue, the less valuable it is to their customers"

"The focus on speed is essential because geospatial data is most valuable when its fresh."

Startup with SoftBank, Airbus investment planning video constellation with several hundred satellites - SpaceNews.com Apr 2018
"A satellite startup that today announced SoftBank, Airbus, Bill Gates and OneWeb founder Greg Wyler as investors says it has plans to field a constellation of hundreds of satellites to provide global video of the Earth, but provided few details on how it will accomplish that goal."

"EarthNow spun out of the business incubator Intellectual Ventures last year with a mission to record the planet and provide video in real time to users on the ground. Airbus is the company’s manufacturing partner, using production lines made to build thousands of telecom satellites for OneWeb in Toulouse, France and Exploration Park, Florida."

"EarthNow’s imaging payload will drive the cost slightly higher than that of a OneWeb telecom satellite, which is estimated at around $1 million each, he said."

"Hannigan said Airbus is building the satellites using an enhanced version of the OneWeb bus produced by OneWeb Satellites, the Airbus-OneWeb joint venture that is building OneWeb’s constellation."

"Hannigan wouldn’t describe the EarthNow ground system, which would likely require either numerous ground stations or inter-satellite links to ensure real time data delivery, saying only that “each satellite is connected to the ground at all times.”"

NASA authorization bill increases emphasis on commercial partnerships - SpaceNews.com April 2018
"A NASA authorization bill to be considered by the House next week would direct NASA to work more closely with commercial partners in areas ranging from Earth observation to deep space exploration.

The NASA Authorization Act of 2018, introduced by Rep. Brian Babin (R-Texas), chairman of the House space subcommittee, was released April 13. The legislation is scheduled to be marked up by the full House Science Committee on April 17."

"One part of the bill, titled “Commercial,” includes a number of sections directing NASA to make use of commercial capabilities in future exploration missions."

"The bill’s commercial language is not limited to space systems. The U.S., the bill states, “should foster the development of U.S. private sector remote sensing capabilities and analyses that can satisfy the public interest in long-term continuous collection of medium-resolution land remote sensing data.”"

Satellite images from highly oblique angles are pretty mindblowing | Ars Technica April 2018
So Simmon began fiddling with some of Planet's satellites, including its 13 SkySats orbiting at 450km above the Earth's surface that have a resolution of 80cm per pixel. Instead of taking overhead images, Simmon began to capture images from highly oblique angles—as much as a 60- or 70-percent difference from directly overhead images.

European Space Agency teams with ICEYE Finnish start-up - BBC News Mar 2018
"The European Space Agency is to work with Finnish start-up ICEYE on ways to exploit its novel radar satellites. ICEYE-X1 was launched in January - the first of multiple spacecraft that will go up in the coming years. About the size of a suitcase, these are the world's smallest synthetic aperture radar satellites and cost a fraction of traditional platforms."

"ICEYE wants to couple this vision with high temporal resolution, meaning a single spot on the Earth's surface would be surveyed several times a day. Algorithms will scour the data to detect significant changes. High-repeat requires a network of satellites, and ICEYE envisages perhaps 30 platforms in orbit."

Debate over interference limits in 26 GHz heats up | PolicyTracker Mar 2018
"A major debate is taking shape for WRC-19 over concerns that mobile use of the popular 26 GHz band for 5G could cause harmful interference to earth exploration satellites in 23.6-24 GHz. The key is to get the emissions limits right, stakeholders say, with a significant gap between proposals from European administrations and those from the mobile industry."

"Rancy believes that if in any frequency band it does not appear possible to design equipment that will protect adjacent bands, those bands will not be accepted for 5G. It’s up to engineers to find the appropriate level of protection for the passive services, he said."

"As ITU studies began ahead of WRC-19, it became clear that using 26 GHz for mobile services could potentially interfere with the very sensitive global warming monitoring being carried out by the European Space Agency (ESA) satellite in spectrum just below 24.25 GHz, Ercole said."

The Afternoon Constellation - A-Train
NASA and its international partners operate several Earth-observing satellites that closely follow one after another along the same orbital “track.” This coordinated group of satellites, constituting a significant subset of NASA’s current operating major satellite missions, is called the Afternoon Constellation, or the A-Train, for short. The satellites are in a polar orbit, crossing the equator northbound at about 1:30 p.m. local time, within seconds to minutes of each other. This allows near-simultaneous observations of a wide variety of parameters to aid the scientific community in advancing our knowledge of Earth-system science and applying this knowledge for the benefit of society. Six satellites currently fly in the A-Train: OCO-2, GCOM-W1, Aqua, CALIPSO, CloudSat, and Aura.

National Space Council backs incremental space regulatory reform - SpaceNews.com Feb 2018
Four recommendations:

1. "calling on the Department of Transportation to replace “prescriptive launch and reentry licensing regimes” with a streamlined system by next March. The recommendation didn’t go into details about that plan, but the Federal Aviation Administration’s Office of Commercial Space Transportation has proposed what it calls a “21st century licensing process” that would address the ability to use the same launch license at multiple sites, or for different versions of the same family of vehicle."

2. "consolidating the Office of Space Commerce and the Commercial Remote Sensing Regulatory Affairs Office, both within the National Oceanic Atmospheric Administration, and placing them in the office of the Secretary of Commerce."

Wilbur Ross: “This elevated and amplified Office of Space Commerce will coordinate all space-related functions at the department: remote sensing, spectrum policy, export controls, business and trade promotion, to name a few.”

3. NTIA "to work with the Federal Communications Commission “to develop protections for the radiofrequency spectrum facilitating commercial space activities.”"

4. "Council’s executive secretary, Scott Pace, to work with members of the Council to develop recommendations on export control reform"

"One topic that did not get much attention in the recommendations is commercial remote sensing regulations, beyond the decision to consolidate the office that licenses such systems within the Office of Space Commerce. Ross noted that commercial remote sensing regulations and their underlying law date back 25 years, but did not propose specific reforms."

Users Advisory Group: "The 29 members formally nominated — their appointments await approval by NASA Acting Administrator Robert Lightfoot, a formality — are heavily weighted towards industry. . . Notably absent from the panel’s membership were executives with companies that provide space services, like satellite operators and commercial remote sensing companies. "

European satellite 'blinded' by radio interference - Oct 2010
The European Space Agency (ESA) said on Wednesday that it had launched a behind-the-scenes campaign to shut down illicit radio and TV transmissions interfering with a major climate satellite.
The 315-million-euro (434-million-dollar) Soil Moisture and Ocean Salinity (SMOS) probe "has been bugged by patches of interference from radar, TV and radio transmissions in what should be a protected band," ESA complained.

Planet sets deadline for Canadian ground station license - SpaceNews.com Feb 2018
"Stymied by extended regulatory delays, Planet is planning to remove a ground station it built in Canada if it does not receive a government license for it by June.

Speaking at the Canadian SmallSat Symposium here Feb. 13, Mike Safyan, senior director of launch and ground stations for the San Francisco-based company, said Planet was still waiting for the Global Affairs Canada (GAC) to decide on a remote sensing license the company needs to operate a ground station it has at Inuvik, Northwest Territories."

"Planet has been caught in an unusual regulatory situation. The company applied for, and received, a radiofrequency spectrum license from another ministry, Innovation, Science and Economic Development Canada. However, it also needed the remote sensing license from GAC even though the satellites that will use the ground station are already licensed by the National Oceanic and Atmospheric Administration in the United States."

"GAC has not been forthcoming regarding the reasons for the delay. “We’ve spent a lot of time with GAC, trying to get our application understood,” Safyan said. “The process is incredibly opaque. It’s very rare that we get any meaningful feedback from GAC.”

Planet highlighted the licensing problem last summer. “It’s been a series of no updates since then, and that’s been a real challenge for us,” he said in an interview after his presentation."

International ground stations tricky for smallsat operators to license - SpaceNews.com
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.”

Spire Global is expanding cubesat constellation to offer persistent global view - SpaceNews.com
"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."
