Launch #11 (Flight ST36) is scheduled to depart 14 October at
6:40pm local time (5:40am ET / 9:40am UTC), with 36 satellites on board and
marks one of the most exciting advances yet for OneWeb’s global communications

these satellites includes several EHP heat pipes, designed & manufactured
within our premises in Nivelles, Belgium.
Our fully-passive heat pipes, equipped with a capillary structure and filled with high-purity ammonia, are a key part of the satellite thermal control.
The dual phase system enables the satellite & the payload to remain within a limited temperature range, despite the very harsh space environment.
In 2016, the OneWeb project started a new era
for EHP with the manufacturing of several thousands of heat pipes within a
timeframe of a few years.
In July 2021, 5 years later, EHP celebrated the
last shipment of this contract. Mission accomplished!
– the several thousands of heat pipes have been
manufactured and 40% of them are already in orbit.
– heat pipes production at EHP has been
transformed: while around 100 items were manufactured on a yearly basis before
the OneWeb project, yearly production reached 3000 items. This high level of
production is ensured for the next years through new contracts.
– new infrastructure have been developed and a
new factory is under construction.
– EHP became one of the world leaders of
space-application heat pipes and has significantly increased its market share.

Concernant la constellation
OneWeb est une
constellation de 648 satellites de télécommunications circulant sur une orbite
basse (1200 km) pour fournir aux particuliers et aux entreprises, à partir de
2022, un accès Internet à haut débit via satellite, en particulier dans les
régions non desservies par des liaisons terrestres.
OneWeb, the Low Earth Orbit (LEO) satellite
communications company, will launch 36 satellites (EHP
Heat Pipes onboard) on Thursday, 1 July
2021, marking the completion of its ‘Five to 50’ ambition enabling connectivity
services for the first time to the 50th parallel and above by the year end.
Each of these satellites includes a set of several heat pipes
manufactured by Euro Heat Pipes in Belgium. This new launch will bring the
total number of in-flight satellites to 254.
Service demonstrations will begin this summer in
several key locations – including Alaska and Canada – as OneWeb prepares for
full commercial service in these regions in the next six months. Offering
enterprise grade connectivity services, the company has already announced
distribution partnerships across several industries including with ROCK
Networks, AST Group, PDI, Alaska Communications and others, as OneWeb expands
its global capabilities. The company continues to engage with
telecommunications providers, ISPs, governments and more worldwide to offer its
low latency, high speed connectivity services and sees growing demand for new
connectivity services to connect the hardest to reach places.
This launch adds another 36 satellites to OneWeb’s 648
LEO satellite fleet that will deliver global connectivity and represents 100
percent of the satellites required to enable its solution to reach all regions
north of 50 degrees latitude.
This launch will enable OneWeb to offer full
connectivity services across the United Kingdom, Alaska, Northern Europe,
Greenland, Iceland, continental U.S., the Arctic Seas and Canada. Commercial
service is expected to be rolled out before the end of the year, and OneWeb
intends to make global service available in 2022.
To mark the fifth and final launch of ‘Five to 50’, with all satellites delivered on time, a welcome message “Hello North Pole” is branded on the rocket, reflecting the significant progress OneWeb has made to secure its Arctic coverage.

for the CAS500-1 system. It will save the time and cost for the development

can be easily commercialized as it can be developed in a relatively short
period of time at a low cost compared to medium to large sized commercial
satellite. In addition to that, by developing multiple satellites in a short
time and operating them simultaneously, it will help satisfy various public
needs for earth observation and reduce the observation interval.
Equipped with a high precision laser, this high-tech machine must allow a serious leap forward in weather forecasts, but also in climate science.
The small Vega launch is preparing to launch this Tuesday from Kourou, French Guiana, the European satellite Aeolus, a high-tech machine designed to measure wind worldwide as part of the Copernicus Earth Observation Program to measure winds from space, Aeolus will experiment with a whole new technology based on a high-performance laser (Lidar for Light Detection and Ranging), that will distinguish the lower layers of Earth’s atmosphere (up to 30km height) to produce vertical wind profiles and gather information about aerosols and clouds. This revolutionary instrument, called Aladin (Atmospheric LAser Doppler Instrument), demanded more than 6 years of development and is equipped with a HP thermal BUS, developped by EHP with the support of Airbus DS NL, that enables an optimised thermal control of the LIDAR.
Today’s daily weather forecasts already contain wind information, including probe balloons and field probes. However, the direct measurements are too fragmentary. Scientists and meteorologists need accurate data on the winds periodically to understand the systems that affect weather and climate and improve their forecasts.
Aeolus will be the first satellite to provide them with this information. The prestigious NASA had developed an instrument based on the same technology for its ICEsat satellite.
The information thus collected will make “not only a serious leap forward in the weather forecasts, but also contribute to long-term climate research”,
A subsidiary of Airbus
The satellite was built by Airbus Defense and Space. A Belgian subsidiary of Airbus, the company EHP, established in Nivelles, was involved in the project. Earlier spin-off of ULB and Sabca, EHP (Euro Heat Pipes) specializes in thermal space control space technology. It provides thermal control equipments based on two-phase heat transfer principles.
Aeolus is part of the European Union Copernicus Program. Copernicus’s ambition is to create a system for monitoring and understanding the environment similar to those found for meteorology. The program includes 6 satellite families (radar image, optical, altimetry, chemical analysis, etc.) dedicated to observing land and sea, as well as monitoring the composition of the atmosphere.
This European Earth observation program will generate a phenomenal amount of environmental data. Due to its long-term character, Copernicus must allow the development of downstream services, which the current scientific satellites do not allow.
This is a spin-off of the French-speaking Free University of Brussels (ULB). This was announced on Monday by Theodorus, the ULB investment fund. The Walloon region now holds 49% via SRIW (the Regional Investment Company of Wallonia) and Sogepa (the French state-owned body investing in European aerospace).
EHP was born of the collaboration, initiated in 2001, of the Faculty of Applied Sciences in ULB, and Sabca (the Belgian aeronautical construction company) to create a laboratory, unique of its kind, based upon microgravity in space. The aim was to create systems and innovations for aeroplane temperature monitoring.
The technology developed by the spin-off involves a cooling system, without using air or any of the aeroplane’s engines. It extracts the heat at source, carries it away and discharges it. The on-board electronic equipment is thus better protected owing to a lower constant temperature. The company says that the reliability of all of the aeroplane’s engines is thus optimised. It further adds that the process is particularly efficient in extreme conditions.
To design, produce and market its inventions, EHP has benefited from the financial support of Theodorus. The investment funds of ULB have acquired 50% of the capital from the spin-off. To enable the project to grow, Airbus acquired an interest in the business, with a shareholding of 16% in 2008. This share will now grow to a total of 51%.
In a few years, the turnover has gone from €2 million to €8 million and the company, based in Nivelles, now employs some 70 employees.
SES-12 equipped with two P-DPS made in EHP was successfully launched to a Geostationary Transfer Orbit (GTO) on Monday, June 4, 2018 from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida.
Liftoff occurred at 12:45 a.m. EDT. The SES-12 satellite was deployed about 32 minutes after liftoff.
The DPS arms are clearly visible throughout the live launch stream.
