1. The long and winding road: making space for everyone

 I founded AeroAstro 26 years ago, having begun working on small amateur satellites in the ’70s, to build satellites in a different way, a more efficient way.  The technologies enabling low cost space or “Microspace” take advantage of scaling to smaller size, mass, dimension and complexity as is true of every engineered product. Still not only is Microspace not widely understood nor accepted but beyond its engineering challenges lies another greater obstacle, the mission mindset, our agenda in space.

Through executive level discussion of the system engineering of the mission, it’s architecture and subsystems I will illustrate the contrasts between conventional and low cost approaches to space.  The obstacles to making the benefits of space accessible to a much broader builder and user base will also be addressed along with some unreliable but hopefully interesting predictions of how the future of accessible space will unfold.

 

2. Re-Architecting Space Systems: Infrastructure Changes Everything

We are immersed in low cost, high performance products.  Smart phones communicate globally and access the internet for 99€, a car to drive across Europe for under 7000€, 2000€ for a small box (a heat pump) that heats your home all winter and cools it in summer, and wide screen viewing of films, sports, news, for the price of a 300€ television and a digital terrestrial antenna.

Infrastructure makes all that possible.  The 1100 km drive from Vienna to Rome without roads, without bridges, without filling and service stations without restaurants, without cell phone or radio, without lighting or even a map becomes just you, your vehicle, a compass and 1100 km of hills, mountains, rivers and forests.  You will need amphibious and off-road capability, tools for clearing trees and boulders, sufficient fuel for 1100 km of off-road range (figure thousands of liters), all the food, clothing, camping, survival and medical gear, weapons for killing animals for food and possibly self defense, to survive probably a month completely out of touch with civilization.  Plus a compass, sextant, star maps, highly accurate time keeping.  If something breaks, you must carry redundant systems and repair tools, backups of everything.  You will need a crew that knows how to use all that stuff and a management structure to run the enterprise.

This is how every space mission has been done since Sputnik..

Our low cost gadgets are merely interfaces to an infrastructure so rich and so ubiquitous that we have ceased to even notice it.  Until we launch into space, where there is none.  Every satellite, even a student-built 1 kg hold it in your hand cubesat, must communicate 1000 km back to it’s own ground station.  It must measure its own orbit, its own attitude.  With no place to plug-in, it must make and store all of its own electrical power.  It is vulnerable to space debris because there is no public health system to keep space clean.

What would space look like if instead of remaining the land of rugged individual pioneers, it became a community welcoming new inhabitants with a range of services they could simply plug into?  It would be much cheaper to inhabit, much simpler to do things in.  It would no longer require a team of experts working for sophisticated companies to get to and to operate in.  Communications would be no harder than your home wifi connection. Navigation like driving with a GPS.

What I have learned in a career working to lower the cost of spacecraft, is that space is still incomparably more expensive, and its cost and complexity keep most of the world out.  Only with infrastructure can we put space in reach of everyone.

Seminar 1 Satellite telecommunication systems: a case study worth to apply systems engineering

Abstract

Satellite systems conceived, designed, realized and deployed for telecommunication purposes are complex enough to deserve a systems engineering approach for all their life cycle. In fact, several complex aspects must be considered for the successful implementation of such systems.

Firstly, the mechanical aspects concerning the orbital choice with related implications in terms of coverage, propagation channel, costs of injection in orbit, dimension of the satellite. Secondly,  the platform over which to develop the electronic part of the satellite.Currently available spacecraft are limited and each has its own constraints. Third aspect is the telecommunication, in strict sense, technology developments. They concern the communication standard (modulation, coding, multiple access, network protocols, etc.), the power needed to satisfy Bit Error Rate requirements (primary quality parameter in any telecommunication system), amd the service and user requirements that are then mapped into system requirements.

Last but not least, the ground segment is crucial to identify and satisfy the target market segment both in terms of performance and costs. Definitively, satellite systems can be classified as Systems of Systems because they involve mechanics, electronics, computer science, telecommunications, market and business models.

The seminar will introduce the main characteristics of constellations (GEO, LEO, MEO, HEO) utilized for telecommunications. Then, the system components will be described: Space segment (Payload), Ground segment (NOC, User terminal) and the integration with terrestrial networks will be addressed. Finally, currently operational services and applications will be addressed to approach the requirements definition (Throughput, Quality of Service, BER, etc.) which will be dealt with regard to a specific study case.

Seminar 2 Satellite networks: the skyway to the Internet

Abstract

Satellite systems can typically play an important role in the information society thanks to their intrinsic capability to serve large areas, to cover where terrestrial systems are not available, to guarantee service continuity in case of disaster, and to even bridge the digital divide. The advent of Internet in daily life in the last decade (social networks, games, shopping, banking, education, medical assistance, etc.) and the challenge of the new requirements (full mobility and ubiquity) and paradigms (Cloud Computing, Software Defined Networks, etc.) increase the importance of this component of the network and challenge researchers to provide improved performance.

The use of P network protocols implies an adaptation to the new paradigms, taking into account the characteristics of the satellite infrastructure.

In particular, the transport protocol TCP (Transmission Control Protocol), which is based on a growing-decreasing window concept to perform congestion control, which is then greatly dependent on the Round Trip Delay (RTT), is negatively affected by a satellite due to the huge delay. Standard TCP over satellite links limits capacity utilization. It is responsible of the difference between the assigned and the experienced capacity.

This protocol is of paramount importance because it is used for almost all Internet applications and recently its use was enlarged to applications traditionally served by UDP (User Datagram Protocol), such as streaming, because it is provided through http protocol.

We can state that the Internet needs satellites to enhance coverage, to guarantee long range mobility, to ensure connection when and where terrestrial facilities are not present or out of order, but also that Satellites need Internet to distribute data efficiently and in standard way, to provide security also to Earth Observation data. Furthermore, satellite systems must tackle new paradigms such as Cloud Computing, Software Defined Network, Network Function Virtualization, Full Mobility, and Security.

The seminar will first address the role that satellite systems can play in the global Internet. Next, it will present the main characteristics of satellite systems having an impact on TCP performance. Specific solutions to improve performance will be presented. Finally, a perspective overview of services and applications provided by satellite systems in the near future will be presented.

Federated satellite systems are a new concept in space systems design that aims to create a commercial cloud-computing environment to enable sharing and trading of in-space resources between spacecraft. Federated satellites exchange resources such as link capacity, processing capability and storage capacity. This exchange improves the efficiency utilization of spacecraft resources and makes use of unallocated resource margins of participating missions. In a commercial perspective, the federated satellite systems concept allows the creation of new markets of in-space resources, among other benefits in spacecraft cost, performance, and reliability. Researchers have begun to explore benefits and costs of a federated approach to spacecraft design, and several research avenues have just started opening in this field.

Topics of interest to the workshop include, but are not limited to:

 

 

  • Heterogeneous spacecraft networks
  • Distributed space systems,
  • Distributed decision making and spacecraft cooperation
  • Satellite Distributed processing
  • Inter-satellite-link payloads
  • Optical space communications
  • Space communication protocols development and standarization
  • Free-space wireless power transmission
  • Fractionated spacecraft,
  • Plug and play space hardware
  • Emerging space network concepts. Space internet.
  • Cloud computing concept transfer
  • Resource management under uncertainty and  network scheduling
  • Advanced space system concepts and architectures
  • Business case studies based on space infrastructures
  • Small satellite distributed and collaborative networks
  • Concurrent engineering approaches to federated systems design

 

This workshop aims to forge links to create a multidisciplinary and international research community that will follow novel approaches to innovate the way in which spacecraft missions are conceived, designed, implemented, and operated. It is through this process that we will create transformational new space science and technology.

Concept papers of up to five pages describing research and concepts related to federated satellite systems and other advanced space system concepts can be submitted online or by email to Skoltech’s Strategic Research Innovation Research Group . Applications will be accepted until September 1, 2014.

Here’s Looking at You: Skoltech Student Startup Secures 1.4 million RUB Funding

Ekaterina Kotenko-Gold of ImageAiry at Russian Internet Entrepreneurship Forum

ImageAiry at Russian Internet Entrepreneurship Forum

Ekaterina Kotenko-Lengold’s day at the Russian Internet Entrepreneurship Forum was fraught with expectation, tension – and hope. The Skoltech student was slated to present her startup, ImageAiry, to the President of Russia. But Vladimir Putin arrived at the Moscow event only after the young entrepreneur was done pitching to potential investors. And still, the pressure was on. She had to secure the vital fuel without which her satellite imaging service cannot get off the ground: money. An hour later Kotenko-Lengold was up in the air. ImageAiry landed 1.4 million RUB in funding.

The seed funding, equivalent to $40,000 USD, was secured through the Russian Internet Initiatives Development Fund (IIDF), with a total valuation of 20 million RUB ($580,000 USD.) Image Airy, founded by Kotenko-Lengold and Alexandra Kudryashova in 2013, touts itself as the “world’s first marketplace for satellite imaging services”. Based on the user’s industry or specific task the search algorithm finds and suggests suitable satellite pictures, imagery resellers or consulting companies which are suitable to business owners’ specific needs. The service might, for example, help tour operators to avoid selling packages to flooded regions or assist agricultural companies seeking high crop yielding areas.

“This is all very, very exciting”, reflected Kotenko-Lengold on her roller-coaster day, “my presentation also resulted in interest for our project from a few senior VCs representing, among others, the Rostelekom Venture Fund, Microsoft Seed Fund and Inventure Partners. Big day, lots of challenges ahead.”
