Gauss Approach to the Lean-Satellite Methodology
INTERNATIONAL WORKSHOP ON LEAN SATELLITE KITAKYUSHU, JAN 22-24 2018 GAUSS APPROACH TO THE LEAN-SATELLITE METHODOLOGY 2018 Riccardo Di Roberto - GAUSS Srl GAUSS Srl History q Early 1990: G.A.U.S.S. (Gruppo di Astrodinamica dell’Università degli studi La Sapienza) was established as a Laboratory of the School of Aerospace Engineering in La Sapienza Rome University. The purpose was to involve directly the students in the design and the manufacturing of University Microsatellites. q Up to 2012: Six microsatellites have been developed and launched into orbitwith Dnepr and Vega launch vehicles. q 2012: Starting from the experience and the enthusiasm grown at the School of Aerospace Engineering, some professors, researchers and students decided to continue the tradition of the school in the private sector. The Italian limited liability company G.A.U.S.S. Srl (Group of Astrodynamics for the Use of Space Systems) was founded. q 2013-2014: GAUSS Srl realized the innovated idea of an autonomous micro-platform able to launch nanosatellites as CubeSats. Since then, two micro-platforms, UniSat-5 and UniSat-6, have carried into space 12 nanosatellites. q 2016 onwards: UniSat-7 micro-platform, with several CubeSats onboard, is under development.

Satellite Constellations - 2021 Industry Survey and Trends
[SSC21-XII-10] Satellite Constellations - 2021 Industry Survey and Trends Erik Kulu NewSpace Index, Nanosats Database, Kepler Communications [email protected] ABSTRACT Large satellite constellations are becoming reality. Starlink has launched over 1600 spacecraft in 2 years since the launch of the first batch, Planet has launched over 450, OneWeb more than 200, and counting. Every month new constellation projects are announced, some for novel applications. First part of the paper focuses on the industry survey of 251 commercial satellite constellations. Statistical overview of applications, form factors, statuses, manufacturers, founding years is presented including early stage and cancelled projects. Large number of commercial entities have launched at least one demonstrator satellite, but operational constellations have been much slower to follow. One reason could be that funding is commonly raised in stages and the sustainability of most business models remains to be proven. Second half of the paper examines constellations by selected applications and discusses trends in appli- cations, satellite masses, orbits and manufacturers over the past 5 years. Earliest applications challenged by NewSpace were AIS, Earth Observation, Internet of Things (IoT) and Broadband Internet. Recent years have seen diversification into majority of applications that have been planned or performed by governmental or military satellites, and beyond.

In standard satellite acquisitions, satellites can take years and billions of dollars to reach operational status. Should there be delays in schedule or on-orbit failures, gaps in data integral to US operations can be lost. -
Thermal Analysis of the SMOG-1 Pocketqube Satellite
Applied Thermal Engineering 139 (2018) 506–513 Contents lists available at ScienceDirect Applied Thermal Engineering journal homepage: www.elsevier.com/locate/apthermeng Thermal analysis of the SMOG-1 PocketQube satellite T ⁎ Róbert Kovácsa,b, Viktor Józsaa, a Department of Energy Engineering, Faculty of Mechanical Engineering, Budapest University of Technology and Economics, H-1111 Budapest, Műegyetem rkp. 3., Hungary b Department of Theoretical Physics, Wigner Research Centre for Physics, H-1121 Budapest, Konkoly-Thege Miklós út 29-33., Hungary HIGHLIGHTS • Thermal analysis of the SMOG-1 picosatellite is presented. • Results of a simple thermal network and finite element methods were compared. • The sensitive battery just fulfills all the requirements for continuous operation. • The thermal network model underpredicts the temperature due to its simplicity. • A simple thermal network is able to predict the temperature variations appropriately. ARTICLE INFO ABSTRACT Keywords: CubeSats have revolutionized the space industry in the past two decades. Its successor, the PocketQube class Picosatellite seems to be a lower size limit for a satellite which can operate continuously and can be received by radio Satellite amateur equipment. The present paper discusses the simulation of the thermal environment of the SMOG-1 Finite element method PocketQube satellite at low Earth orbit by both thermal network and finite element models. The major findings Thermal network of the analyses are the following. Even a single node per printed circuit board model can provide adequate Thermal analysis information about the thermal behavior without tuning the physical parameters. By applying a finite element Low Earth orbit model with few magnitudes more nodes, the predicted inner temperature increased as the losses were reduced in the radiation-dominant environment compared to the thermal network model. -

Session 1 – SEGMENTED ARCHITECTURES/DISTRIBUTED SYSTEMS
Session 1 – SEGMENTED ARCHITECTURES/DISTRIBUTED SYSTEMS SAR Satellite Mission Analysis and Implementation with Along-Track Formation Flying - IAA-LA2-01-01 Leonardo Cappuccio*; J. Lugo; P. Weder / INVAP *[email protected] Over the last few years, there has been a definite trend in the satellite industry that shows distributed mission concepts being increasingly considered in satisfying a vast diversity of needs. Some of the distributed missions are designed to fulfill specific goals which would not be possible to accomplish with monolithic satellite missions. Others take advantage of the new distributed scenarios to further optimize previously existing systems. A particular case is the utilization of the distributed concept to enhance some capabilities of satellite Synthetic Aperture Radar (SAR) missions. In this context, an along-track flying formation composed of two polarimetric satellites is introduced, as a feasible alternative to single satellite SAR. This new approach is driven by a reduction of size and mass per satellite, making them suitable payloads for less expensive launch services. As an additional advantage, a supposed critical failure in one of the satellites would not imply the end of the whole mission, but only a degradation of the achieved performance. Replacement of a damaged satellite may also be considered, since it would represent a reduced fraction of the overall mission cost. Another interesting fact is that multiple mission phases, each with different formation geometries, could be possible as well, so that the same system could also be used, for example, in across-track configuration. The segmented architecture SAR presented in this work is possible because it relies on the reception of the echo information from two independent phase centers, one per satellite. -
