The DESTINY + (Demonstration and Experiment of Space Technology for INterplanetary voYage with Phaethon fLyby dUst Science) Dust Analyser (DDA) is a state-of-the-art dust telescope the in situ analysis cosmic particles. As primary scientific payload mission, it serves purpose characterizing environment within Earth–Moon system, investigating interplanetary interstellar populations at 1 AU from Sun studying cloud enveloping asteroid (3200) Phaethon. DDA features two-axis pointing platform...
Downlink measurement campaigns from the optical downlink terminal OSIRISv1 onboard LEO satellite Flying Laptop were carried out with French Observatoire de la Côte d'Azur and two Optical Ground Stations of German Aerospace Center. On/off keyed data at 39 Mb/s modulated on laser signal, according telecom reception was performed by ground stations. The pointing achieved open-loop body orientation, its star sensor as attitude control signal. We report here measurements investigations signal...
Abstract The 6U CubeSat EIVE was developed for the verification of an E-band link from space to ground. Establishing such a presents challenging requirements development attitude control system CubeSat. To verify functionality its components, both sensors and actuators, number tests were conducted prior launch. These ranged simple performance accompanied by calibration campaigns. Qualification algorithms proved be challenge, as fitting simulator setup not available. Therefore, limited...
Meteor plasmas and impact events are complex, dynamic natural phenomena. Simulating these processes in the laboratory is, however, a challenge. The technique of laser induced dielectric breakdown was first used for this purpose almost 50 years ago. Since then, laser-based experiments have helped to simulate high energy Tunguska Chicxulub events, heavy bombardment on early Earth, prebiotic chemical evolution, space weathering celestial bodies meteor plasma. This review summarizes current...
This paper presents ongoing activities towards an in-orbit verification of E-band high bandwidth communication system to exploit a new spectrum for broadband satellite by demonstrating data-downlink, using solid state technologies the RF analog transmit front end, in frequency range 71-76 GHz with data rate 5 Gbit/s from three-axis stabilized 6U nano-satellite low earth orbit ground station. A recent plane-to-ground transmission has successfully validated technology platform, and dynamic...
Abstract The 6 Unit CubeSat EIVE was developed to host a novel high-speed E-band transmitter payload. Challenging aspects for reliable and demanding satellite architectures were revealed during development operations. Reliable communication buses such as CAN, RS485 or point-to-point links should be preferred over I2C SPI. Experiences from the implementation of individual subsystems are presented lessons learned derived in this paper. on-board data handling system is based on system-on-a-chip...
The European Space Agency (ESA) is currently concluding a dedicated technology development to mature and finalize the Nanokhod microrover into complete engineering model with integrated geochemical payload package. goal of this build test such that it can serve wide range mission applications in future. rover will be able deliver scientific payloads not only atmospheric planets as Mars but also environmentally more extreme nonatmospheric celestial bodies Mercury or Moon. payload-efficient...
This contribution details the motivation and status of a new satellite mission, which targets in-orbit verification wideband communication link operating in high millimeter-wave regime at 71-76 GHz. The paper reviews dynamic budgets for data links between satellites low-earth orbits ground stations on close to sea level, taking into account expected atmospheric attenuation according lTU models supported by successful terrestrial transmission experiments, confirm feasibility attractiveness...
In order to reduce the costs of integration and verification processes optimize assembly, (AIV) flow in prototype development small- medium-sized spacecrafts, an industrial six-axis robot was used as a universal mechanical ground support equipment instead tailored specific (GSE). particular, robotic platform offers possibility embedding steps such mass property determination into process while offering wider range ergonomic adaption due enhanced number degrees freedom compared classical...
This paper introduces the system architecture, implementation and measured characterization of FPGA-based adaptive onboard payload computer used for an in-orbit verification E-band high bandwidth communication system. The mission goal is to evaluate atmospheric effects on a multiGigabit data-downlink, in frequency range 71-76 GHz with data rate minimum 10 Gbit/s, from 6U CubeSat low earth orbit ground station. miniaturized conjunction fast digital-to-analog converter shall serve as arbitrary...
Abstract Collision avoidance is a topic of growing importance for any satellite orbiting Earth. Especially those satellites without thrusting capabilities face the problem not being able to perform impulsive collision manoeuvres. For in low Earth orbits, though, perturbing accelerations due aerodynamic drag may be used influence their trajectories, thus offering possibility avoid collisions consuming propellant. Here, this manoeuvring option investigated Flying Laptop University Stuttgart,...
A major concern of a university satellite mission is to download the payload and telemetry data from satellite. While ground station antennas are in general easy with limited afford procure, receiving unit most certainly not. The flexible low-cost software-defined radio (SDR) transceiver "BladeRF" used receive QPSK modulated CCSDS compliant coded HAM S-band. control software based on Open Source program GNU Radio, which also perform post processing binary bit stream. test results show good...
This paper presents the concept of a community-accessible stratospheric balloon-based observatory that is currently under preparation by consortium European research institutes and industry. The planned Stratospheric Balloon Observatory (ESBO) aims at complementing current landscape scientific ballooning activities providing service-centered infrastructure tailored towards broad astronomical use. In particular, focuses on reusable platforms with exchangeable instruments telescopes performing...
Stratospheric balloons offer accessible and affordable platforms for observations in atmosphere-constrained wavelength ranges. At the same time, they can serve as an effective step technology demonstration towards future space applications of instruments other hardware. The UV Demonstrator Imaging Observatory (STUDIO) is a balloon-borne platform mission carrying imaging micro-channel plate (MCP) detector on 0.5 m aperture telescope. STUDIO currently planned to fly during summer turnaround...
