• December 14, 2021: Astrocast and the Access to Water Foundation announced their collaboration today. Aiming to have both parties working together to connect 150 water points in 2022 in Senegal. The stations, developed with the support of Bank Lombard Odier & Co Ltd, will be mainly located around schools and health points.

- The United Nations classifies Senegal as a water-poor country with less than 1,000 m3 per capita, while countries like the USA have almost 10,000 m3. About 20% of its population does not have access to clean water. The installation of these water points in strategic areas of Senegal will provide the opportunity to almost 5% of the Senegalese population to get drinkable water.

- "Using Astrocast's IoT connectivity solution, the Access to Water Foundation can deploy its water treatment points anywhere and contributes to the effective fight against diseases related to dirty or polluted water, including in remote and rural areas not covered by local telecom network," says Renaud de Watteville, Director of the Access to Water Foundation.

- "We are excited about this collaboration and the opportunity it represents for us to contribute to improving people's lives by leveraging our technology," according to Gildas Seimbille, Customer Success Manager at Astrocast.

- The machines will be presented during the World Water Forum in Dakar in March 2022, and their installation is planned to start in April 2022.

• August 31, 2021: We are thrilled to announce today that Wayra Germany brings Astrocast and Telefónica together for an IoT product collaboration in its new 5G Tech Lab. Wayra Germany is the open innovation hub of the telecommunications group Telefónica. Their goal is to identify start-ups that can work with Telefónica's business units, starting with a pilot project. 11)

- Astrocast's module and antenna integrate with Telefónica trackers

- Thanks to the Astronode S module and the Astrocast nanosatellite network, this new product will enable direct-to-satellite, bidirectional communications between trackers in the world's most remote regions and headquarters. Telefónica customers will be able to collect data from and send updates and commands to trackers no matter where they are. The final proof-of-concept is showcased in the 5G Tech Lab today.

- Telefónica takes IoT further with Astrocast. Telefónica delivers state-of-the-art IoT equipment and connectivity for both personal and industrial use. With Telefónica sensors, customers can track, secure, optimize and even predict the maintenance needs of the assets they are tracking. From cars to people, Telefónica is enabling companies to create their own IoT journey. By collaborating with Astrocast they can take the journey further, faster.

- "The key IoT-use case is to never lose track of your assets. Using Astrocast nanosatellite network, we can extend our trackers' reachability worldwide in order to enable customers to collect critical data in areas that were not reachable before in an economically reasonable way," said Peer Lodbrok, Director MNC Germany & Switzerland of Telefónica Global Solutions.

• July 26, 2021: Communications satellites bring us television, telephone, TV and internet connectivity. They are big beasts, can be as tall and heavy as an elephant, cost above 100 million to build, and as much again to be launched to their geostationary orbit 35,786 km above the equator. These satellites are powerful but offer costly service, often too expensive for applications that need just a tiny little amount of data transmitted. In fact, there are countless man-made objects all around the world that would require exactly that: Picture buoys in the middle of the ocean that measure the salinity of the water. A piece of industrial equipment in a jungle that needs to be tracked. A gas or water tank in a remote desert, whose proprietor would like to know from time to time how much there is left in it. For such objects, it would be enough if they would just send a text message home from time to time – but of course, there is no mobile coverage where they are. In fact, on about 90% of earth's surface, there is no signal at all, as these vast land masses aren't even covered by 2G service. The only way to communicate, hence, is via satellite. And the way to make communication via satellite cheaper is by shrinking them. 12)

- Fabien Jordan is a pioneer when it comes to satellites of the smaller kind. As an Electrical Systems Engineer for the Swiss Space Center of EPFL in Lausanne, he worked on Switzerland's first satellite, the SwissCube. Compared to the elephant satellites in space, this was a small rabbit, weighing just one kilogram. Fabien leveraged the experience he gained with this project and founded Astrocast in 2014 together with Space Systems Engineer Federico Belloni. Their vision was to create global direct-to-satellite communication for the emerging Internet of Things. Now, the company is getting there, as its commercial service is about to be launched.

- In a small office building close to Lausanne, engineers are busy building Astrocast's nanosatellites. They are 3U satellites, one "U" refers to the standard unit of 10x10x10 centimeters. In 2021, Astrocast launched 10 of them already. They are fully functional and rotate about a dozen times around the earth in a distance of about 500 km. Because they aren't geostationary, Astrocast needs 100 of them to cover every spot of the earth all the time. The company is on track to reach that goal by 2024. However, for applications that don't need constant connectivity, a smaller constellation is already good enough, which means that Astrocast's system already provides commercial value even when it's not complete.

- To connect to the satellites, an object needs to be equipped with an antenna. In this case, this antenna is just a small chip with very low power consumption, orders of magnitude less power-hungry than what competitors can offer. (The reason for this is that through a partnership, Astrocast can use a frequency called L-Band that allows for miniaturized antennas.) This matters; if you have thousands of assets in the middle of nowhere, you don't want to visit them often to replace batteries.

- Launching small satellites into space has become a big business. SpaceX with its Falcon 9 rocket has made launches more affordable, and the number of small satellites deployed every year has risen to a few hundreds. The satellite IoT market is expected to grow massively over the next few years. By 2025, the number of connected devices is estimated to surpass 30 million. Astrocast is well-positioned to grab a large share of this market because no other company will be able to deploy a comparable constellation of nanosatellites as quickly as they do. The startup is in advanced discussions with dozens of clients from diverse industries, and some of them plan to connect tens of thousands of devices as soon as they can.

- Even if the cost to build and launch one of Astrocast's satellites of about half a million dollars is fairly modest compared to larger satellites, the company still needs to raise a significant amount of capital to finance the whole constellation. (Having raised 22 million Francs in the past, Astrocast is currently raising up to 50 million Francs in a private placement.). This is why the company plans to go public and list on Euronext, to broaden its investor base. Astrocast believes it is in a good position to become a market leader in IoT. The chips and communication protocol were developed in-house, the company will control its whole system. And the management team has a strong track record in space. Chairman José Achache was director at the European Space Agency and architect of the Sentinel series of satellites of the Copernicus program. CFO Kjell Karlsen helped lead multinational spacecraft company Sea Launch for 14 years. And Corry Brennan, Head of Sales, has more than 20 years of experience in telecom and aerospace.

- As Astrocast launches more and more nanosatellites over the next few years, the availability of connections to the system will increase, and more and more customers will come on board. The business model is simple: Astrocast charges a monthly subscription fee for every device connected to its system. (It also sells the antenna chips to the clients, but aims to keep their price low to drive adoption.) Due to the significant capital expenditure for the launch of the satellite, the company will still be loss-making for at least 2022 and 2023. Astrocast is convinced that as a leading IoT company, it can offer high-margin data plans others simply cannot. Verve Ventures has backed the company as early as 2017, when we first invested in Astrocast's Seed financing round.

• January 25, 2021: Today aboard the SpaceX Falcon 9 Rocket, aboard Spaceflight rideshare services, the first 5 nanosatellites of the Astrocast Nanosatellite IoT Network were launch. With this launch Astrocast goes commercial and begins to enable companies to track, measure, manage, communicate and control IoT assets from the world's most remote regions. 13)

- "This is a critical milestone for both Astrocast and a long list of customers and partners. With the Astrocast Network our customers will have two-way communications with their IoT assets even into some of the world's most remote and challenging regions. And these 5 satellites are just the beginning," says Fabien Jordan, Astrocast CEO.

- And these 5 satellites aren't just any satellites. This is the most advanced nanosatellite constellations in the world today. We have increased the power and performance of our nanosatellites significantly. Today's Astrocast nanosatellites have 100 times more communication speed and onboard storage. Our Network also features:

a) Low-latency communications from asset all the way back to headquarters

b) Global L-band spectrum

c) Ultra-low power terminals with low-profile patch antennas

d) Two-way communications

e) Satellite propulsion to avoid debris in space

f) In addition, the Astronode S is two to three times less expensive than conventional bidirectional satellite IoT terminals.

- And the best is yet to come. We are moving aggressively to grow this constellation and will have two more launches within the year for a total of 20 satellites by year end. So watch this space. We have a lot more to show you!
