HPS: On the Fast Track Towards Success
3 million more for next-stage development of deorbit device ADEO
With the support of the German Space Agency delegation HPS has been awarded a 3-million Euro GSTP-contract with ESA for development and manufacturing of a large passive dragsail version of ADEO with presumably about 25 squaremeters in size. The goal of the activity is the delivery of a flight ready protoflight model prepared for an in orbit demonstration mission as early as 2020. Final design and size – on the basis of a market analysis currently undertaken– will be frozen in December 2018.
Like projects on system level, for example, ARIANE, GALILEO and COPERNICUS, ADEO on the subsystem level is classified as one of Europe´s „lighthouse projects“ in space, since
- a solution for fast deorbit of satellites especially from the very crowded LEO orbits at 300-750 km perigee is the absolute prerequisite for sending future single satellites and even whole constellations of short-lived satellites into space in the first place
- ADEO by HPS is Europe´s top chance to gain and keep the globally lead position on the emerging world market with a critical technology ensuring the continent´s independence in space.
- ADEO will in the end address the market commercially and consequently create new jobs as well as contribute to yet another increase of the return-on-investment ratio of public funding in space.
While a 2.5 squaremeter ADEO-N test version is waiting in New Zealand to go on its „Pride of Bavaria“-mission on top of the Electron rocket (#ItsBusinessTime of Rocket Lab USA), this second development – ADEO-L – represents an upscaled version of just 10 Kilo mass and 25 squaremeters enabling passive de-orbiting without the need of any extra propulsion. Due to its virtually unlimited variability and scalability ADEO can be applied to return dead satellites of any size and mass. For example, the current version supported by ESA (and DLR) will reduce the time for disposal of a 500 kg satellite at 650 km altitude from 460 years down to just 11 years, while the small version currently mounted on top of Electron could drag for example a 10 Kilo cube satellite (6U = 30cm x 20cm x 10cm) down from a 500km orbit in 77 days instead of 26 years.
The large version is planned be applied as a protoflight model to a 200-1000kg satellite with an In-Orbit Demonstration as early as 2020. The In-Orbit Demonstration planning phase has already started and HPS is looking among other things for satellite providers that would take the PFM onboard their missions free of charge.
The ADEO subsystem is designed, assembled and tested by HPS as prime contractor of ESA and supported by eight subcontractors, 5 of them being SMEs. Main subcontractors are DLR institutes Bremen and Braunschweig and RUAG Space Germany (formerly HTS).
Pride of Bavaria
Anlässlich der bevorstehenden Weltraummission „Pride of Bavaria“ zum Test der Nano-Version von ADEO, des künftigen Space-Segel-Subsystems zur schnellen Rückführung ausgedienter Satelliten, besuchte der bayerische Wirtschaftsminister Franz-Josef Pschierer am 24. Mai 2018 die Innovationsschmiede HPS GmbH, München, um sich persönlich von dem Stand des Vorhabens zu informieren.

Rocket Lab reschedules next Electron launch
LOS ANGELES — Rocket Lab announced May 25 it has rescheduled the next launch of its Electron small rocket for late June after correcting a problem that delayed an April launch attempt.
That launch, dubbed “It’s Business Time” by the company because this is the first commercial Electron launch after two test flights, is now scheduled for no earlier than June 22 (U.S. time) from the company’s New Zealand launch site. Four-hour launch windows, opening at 8:30 p.m. Eastern time, are available daily through July 5.
The company had planned to carry out the launch in April but postponed the launch after detecting a problem with a motor controller for a pump in one of the rocket’s nine first stage engines. At the time of that delay the company hoped to reschedule the launch for May, but diagnosing the problem took longer than expected.
“During the wet dress rehearsal we saw some really weird behavior in one of the motor controllers,” Peter Beck, chief executive of Rocket Lab, said in an interview. “We couldn’t quite explain it. It was one of these faults that had a really non-obvious root cause.”
Beck said that the company decided to stand down until they could find and correct the motor controller problem. “The fix was actually relatively simple,” he said, not elaborating on the technical details. “It’s a really a change to process rather than to hardware.”
Part of the rocket is already back at the launch site, he said, with the rest arriving by May 28 to begin pre-launch preparations. Beck said that the company made no other changes to the rocket while correcting the motor controller issue.
Rocket Lab did use the delay to add two more satellites to the vehicle. One, Irvine01, is an educational payload developed by the Irvine CubeSat STEM Program, an organization that includes six high schools in Southern California. The other is NABEO, a payload developed by High Performance Space Structure Systems GmbH that will test a deployable drag sail that can be used to deorbit satellites.
Beck said that Rocket Lab was already in discussions about flying those satellites on a later mission when the opportunity opened up to include them on this launch. The company has been building up capabilities to quickly do the necessary analysis for integrating payloads on its rockets.
Those payloads join three others previously manifested on the rocket. Two are Lemur-2 satellites from Spire and one is a satellite built by Tyvak Nano-Satellite Systems for GeoOptics. All the payloads will be launched into an orbit of 250 by 500 kilometers at an inclination of 85 degrees, after which a Rocket Lab kick stage will circularize the orbit.
Despite the delay, Rocket Lab is still planning to reach a cadence of one launch a month this year. Beck said that the next launch, for NASA’s Venture Class Launch Services program, will be “pretty close on the heels” of this launch, but the company hasn’t announced a launch date for that mission yet.
Rocket Lab says its third Electron launch, called „It’s Business Time,“ will be delayed a few weeks because of a problem detected in a recent wet dress rehearsal. © Rocket Lab
HPS Gestão e Engenharia, Lda, European Spacetech player with New Ownership
Leading Engineering Portuguese FREZITE Group is Building up its Activity on the fast Rising Space Market.
Effective 20th of April 2018 the European HPS‐Group hands over its subsidiary “High Performance Structures Gestão e Engenharia, Lda” (HPS Lda), Porto, to the leading Portuguese technology‐group “FREZITE”. The German “High Performance Space Structure Systems GmbH” (HPS GmbH) had founded HPS Lda back in 2007 and developed it to one of Europe´s first class addresses especially in the field of tailor‐made insulations (MLI, Multilayer Insulation) for satellites and instruments.
The decision reflects the firm conviction of both industrial groups involved that HPS, Lda will profit from growing now even faster and that the envisaged future cooperation presents a win‐win situation for all of the three parties, keeping its renowned flexibility advantage to its customers.
The Portuguese FREZITE Group follows its clear strategy of fast and significant growth as well as for focused diversification in high added value technologies. With HPS Lda it expands its up to now terrestrial product portfolio into space – a field that especially in Portugal represents a strongly growing national as well as export market. FREZITE Group is a set of engineering companies acting on the industrial technologies and began its activity in 1978 with the aim of producing and selling precision and high‐tech tools and systems for wood works, plastics, composite and metal materials. Today the Group is present with its 500 employees directly in more than ten countries spread over the world, supporting demanding industrial processes of its customers. This background will give a considerable push to its new member HPS Lda especially when targeting the markets of “NewSpace” and for spinoff terrestrial products. FREZITE Group will, at its new subsidiary, invest into facilities, manufacturing‐, and test equipment in order to drive with this expansion especially HPS Lda´s innovative product‐lines of MLI, composite based technologies, and deployable masts. Additional growth in high qualified staff will help to even further accelerate processes as well as to broaden the services.
That given, HPS GmbH, Munich, will, with an even more powerful engineering and manufacturing partner in Portugal, drive the company´s profile as developer and supplier of high performance thermo‐mechanical subsystems, now at a significant higher intensity. The additional funds generated through the sales of shares in HPS Lda will be used, among others, to boost with massive investments the company´s two largest fields of innovation, the dragsail subsystems for clean deorbiting of satellites at the end of their life circles and the deployable large antenna‐reflector subsystems for telecommunications and earth observation missions. Also, the traditional antenna portfolio of the company will be widened. On international level, HPS GmbH plans to push its Bucharest‐based subsidiary “High Performance Structures Inovatie si Dezvoltare S.R.L.” (HPS S.R.L.) even faster than originally foreseen to become one of Romania´s space market leaders, for example in the area of mechanical satellite equipment.
The name HPS Lda will be changed still this year. FREZITE, HPS Lda and HPS GmbH are looking forward to the new challenges that the space market brings to both companies.
Integration und Tests bei IABG: Zwei Riesenprojekte von HPS auf der Zielgeraden
In den Hallen von Europas hoch renommiertem IABG-Raumfahrttestzentrum ist in diesen Märzwochen das Logo von HPS fast überall anzutreffen. Denn mit HPS Deutschland und HPS Portugal sind gleich Teams von zwei der drei Werke des europäischen Subsystemspezialisten vor Ort; parallel integrieren und testen sie Beiträge der HPS-Gruppe für zwei bedeutende europäische Raumfahrtprojekte: die EUCLID-Mission und die strategisch wichtige Entwicklung eines extrem präzisen Antennenreflektors made in Europe.
EUCLID ist eine ESA-Mission zur Kartierung der Geometrie des Dunklen Universums durch Messung der Distanz-Rotverschiebungsrelation und Entwicklung kosmischer Strukturen von Galaxien entsprechend einem Rückblick auf 10 Milliarden Jahre.
Um das im Raum leisten zu können hat das deutsche KMU Spacetech (STI) HPS Lda Portugal mit der Entwicklung und Produktion einer hocheffizienten MLI-Isolation für das 4m Sonnenschild des Raumfahrzeugs beauftragt. Zudem hat das Team aus Portugal einen Integrations- und Drehsockel gebaut und installiert, um das Sonnenschild um 180 Grad drehen zu können wie auch später die Solarpanele.
Insgesamt hält die HPS-Gruppe sechs Aufträge für spezielle Beiträge zu diesem Riesenprojekt der ESA. Unter anderem und neben dem MLI für das Sonnenschild produziert die HPS-Gruppe den Ka-band Antennenreflektor (Euclid-ARA); das Qualifikationsmodell befindet sich schon in finaler Fertigungsphase.
Zur selben Zeit testet HPS Deutschland bei seinem langjährigen Partner IABG den neu entwickelten 2,4-Meter Q/V-band Reflektor, entwickelt im Auftrag der ESA unter anderem auf thermoelastische Deformations-, Vibrations- und Akustikeffekte. Das Projekt begann 2014, die Geschichte der Technologie-Entwicklung datiert zurück auf das Jahr 2003. Das Design stammt von HPS, der Zusammenbau erfolgt gemeinsam mit INVENT, welches mit zehn Prozent an HPS beteiligt ist. Herausragende Qualitäten des Reflektors sind u.a. extrem günstige Relation von Gewicht und Eigenfrequenz, sehr geringe Deformationstoleranzen im Raum und die Anwendbarkeit für „Big Data“-Projekte im Zukunftsbereich New Space.
Während die laufenden Test- und Integrationsprozesse bei IABG im April abgeschlossen werden, wartet schon eine ganze Reihe neuer Projekte auf die Teams, die nach München und Porto zurückkehren. Einige davon bewegen sich in der Größenordnung von Multimillionen Euro-Budgets. Um nur drei hervorzuheben: MLIs für ESA-Missionen auf Instrument- und Satellitenlevel, die neue Ka-band Antenne für die Heinrich Hertz-Mission, beauftragt von TESAT für die Kunden OHB und DLR, und ein großes entfaltbares Segel für das Deorbiting von Satelliten am Ende ihres Lebenszyklus.

DORA-Spaceborne Doppler Radar Concept to drive European leadership in climate monitoring
– Innovation by HPS Germany and Portugal on demand of the European Space Agency ESA –
One of the most fundamental preconditions to understand climate change is the provision of reliable precision data about the behavior of factors affecting and influencing climate and weather phenomena. For meteorologists and climate researchers wind is one of those most decisive factors – however, even after more than a century of professional and scientific studies executed from positions on the ground and airborne among others one question still needs to be answered: Do winds follow the logic of a certain „structure“ underlying this phenomenon, and how can that „structure“ be described? Systematic research may well lead not only to a better theoretical understanding, but also to practical solutions towards the predictability of impacts that directly concern safety and wellbeing of humans on the ground, on the water and in the air.
The European long-term lighthouse program in space called „Copernicus“ foresees a huge number of missions dedicated to finding answers on those questions from space. One of potential future missions named “CIMR” foresees the use of a rotating 8m-deployable reflector subsystem, for which currently ESA is requesting proposals for a Phase A/B1.
Another advanced potential mission concept needs a 3m rotating shell reflector cluster subsystem measuring winds in cloudy regions with 50km horizontal and 1km vertical resolution on a swath width greater than 800 km. Before even planning a mission like that a completely new technology is needed. The pre-development has been entrusted to HPS (Germany and for the breadboarding-part, Portugal) back in 2015. Within time and budgetlines HPS successfully came up with a solution of a conically scanning Doppler radar with the following characteristics:
- Polarization diversity
- Pulse compression (for higher resolutions of targets)
- Frequency “hopping” (jumping from one frequency to another 94 GHz +/- 0,25 GHz).
The design of the new conical scanning antenna is compatible with the fairing of Europe´s lightweight-launcher VEGA. The 3m-antenna is to rotate on top of the satellites at the speed of one round every 5 seconds and all electro-magnetic waves are focused in a 2 mm diameter wave-guide entry. Most critical section of the subsystem is the subassembly of two secondary reflectors and rotating tiny feeds in W-band. Therefore ESA agreed for a breadboard concept architectured by HPS Germany, designed in detail, manufactured and assembled by HPS-Portugal and tested at DLR in Oberpfaffenhofen.
- The accuracy (around 10 µm RMS) of the free space part of the breadboard has been reached by HPS Portugal
- The proposed antenna system is fully compliant with the system requirements
- The RF tests on the breadboard have given very good results.
- Cooperation among all partners, especially those involved in the breadboarding activity has been Excellent.
The whole team responsible for the latest technological breakthrough of Europe consisted of:
- HPS Germany as Prime
- Thales Alenia France as LSI for system inputs and instrument specification
- University of Leicester for the science part
- HPS Portugal for breadboard/ strcuture assembly as main subcontractor with the largest portion of the budget
- SWISSto12 for RF-parts in 3D-printing technology.
Europe´s ambitious Copernicus program constantly needs innovations and even disruptive developments to reach its goals. HPS (Germany and Portugal) has become one of the principal suppliers of technological breakthroughs on demand.

Copernicus Sentinel-4: Europe´s Lighthouse Project in Space Takes Shape
HPS Portugal Ready Now for Manufacturing the Original Flight Model´s Insulation (MLI)
Based on a budget of nearly seven billion euros “COPERNICUS” is one of the three most ambitious and advanced space programs orchestrated by the European Commission (EC). “Sentinel-4” is one of the cornerstones to this program. It consists of two payloads to be launched on Europe´s third generation of Meteosat-satellites with a clear mission: observing the earth with special focus on climate and climate change monitoring.
At the heart of the new Copernicus technology is an optical state-of-the-art camera operating in the ultraviolet, visible and near infrared spectrum. Engineering and design of the payload are under way since 2013.
At that time Europe´s industrial prime Airbus Defence & Space (Germany) alongside its subcontractor OHB (Munich, Germany) selected HPS (Munich, Germany and Porto, Portugal) as one of the leading experts for multilayer insulation (MLI) in an open Europe-wide competition under best practices-criteria; HPS is specialized on and perfectly equipped for design and production of extremely clean MLIs for optical space instruments.
The contract covers two complete flight models of MLI for the Copernicus satellites, including almost one hundred blankets in each set at sizes ranging from 5×5 cm to larger than 1×1 meter. The qualification model had been delivered to OHB already in summer 2017, so that there is now the green light for the expert-team of HPS in Portugal to start manufacturing of the original flight models. They will be delivered to OHB in summer 2018.
Besides managing the steadily growing demand for top quality MLI, HPS has been selected lately as the leader of a European consortium for design, engineering, and manufacturing of one of the most urgently needed new European space technologies, the deployable large European space antenna (LEA). This contract in the frame of H2020 program of the EC alone has a budget volume of five million euros. Along with the steadily increasing demand for MLI made in Portugal, HPS Lda. is currently expanding its workforce in the area of highly qualified Portuguese engineers and technicians by twenty percent.
