      Where is Galileo? We know who knows!

      ​On 24 May 2016 at 10:48 CEST, another two Galileo satellites are scheduled to launch from Europe’s Spaceport in French Guiana. They will join the existing constellation of 12 navigation satellites orbiting our Earth.

      Navigation is highly important for institutional, private and commercial users on our planet; accurate positioning is useful for all types of transportation, agriculture, and also the casual athlete on their Sunday run. But we need to know one thing first to determine our position on the Earth: where the satellites actually are!

      Navigation for Navigation

      We spoke to two of our Telespazio VEGA colleagues in the Navigation Support Office at the European Space Operations Centre (ESOC) in Darmstadt, who can answer this question. Telespazio VEGA is one out of several companies involved in the Navigation Support Office activities.

      We are looking forward to the time after the launch,” explains Gwendolyn Läufer, Navigation Engineer in the ESOC Navigation Support Office. “Our work starts during the commissioning phase, the moment the satellite starts transmitting signals, a couple of weeks after launch Users are waiting to see how the navigation solutions improve with two more satellites added to the constellation. And we want to be the first to impress them with centimetre-level orbit predictions of the satellites, predictions that are necessary for the most exciting and exact uses of navigation signals.”04-Navigation-Facility-Vorauswahl-13x19cm-JMai_6763.jpg

      These accurate orbit predictions are possible because of one special fact about navigation satellites: they are constantly broadcasting a signal specifically designed for positioning!  This signal can be received by Galileo receivers all around the Earth; in turn, these receivers provide a constant flow of highly accurate position information used to measure and predict the precise Galileo satellite orbits. In contrast, the orbits of other spacecraft, for example interplanetary probes, must be determined using only their own instruments and information from short uplink and downlink sessions with the ground.   

      Something to be proud of

      The Navigation Support Office was the first analysis centre to perform precise orbit determination for newly launched Galileo satellites,” adds Adam Vigneron, Software Engineer and also Telespazio VEGA colleague. “It's something we're quite proud of!  Imagine this: We calculate a prediction of the satellite’s position with an accuracy of up to 5 centimetres, with the satellite moving at a distance of 23.222 km from Earth. That’s comparable of knowing the position of one human hair currently moving around Wiesbaden while we are on Darmstadt’s Mathildenhöhe!”

      Gwen and Adam confirmed they would both be watching the Galileo launch on 24 May to have a first look which challenges lie ahead. We wish them and the Navigation team an exciting run for the first orbit determination!

      Telespazio VEGA and Galileo

      Telespazio VEGA is highly involved in Galileo in many aspects. Throughout our company, around 35 people are contributing to the programme, among others in the ESOC Navigation Facility.

      In the Software Solutions area, Telespazio VEGA is or has been in charge of different ground systems for Galileo, constantly evolving with the system’s needs:

      • For the development of the Constellation Simulator (CSIM) for the entire Galileo constellation, and related trainings of the Flight Control Team
      • As Prime-Contractor for the development of the hardware-in-the-loop simulator
      • As the company in charge of the Assembly, Integration & Validation Platform (AIVP) for the Ground Mission Segment
      • During the In-Orbit-Validation-Phase (IOV), we supported the testing and validation of the very first four Galileo Satellites
      • We developed the Galileo System Simulation Facility (GSSF): a tool to assess the functional and performance behaviour of the Galileo satellite navigation system
      • Several colleagues have been involved in the Mission Segment Validation through the Thales Alenia Space team in Ditzingen, Germany.

      Prior to the launch, our colleagues in the ICT Team located at ESOC in Darmstadt have ensured that the networks and ICT systems are optimised for the LEOP. With this in mind, we are ready for operations! 

      And we are also proud that a large number of our staff are or will be part of operations during the Launch and Early Orbit Phase (LEOP) and then later for routine operations.

      • At the Galileo Control Centre in Oberpfaffenhofen, Telespazio VEGA forms a large part of the permanent Flight Control Team and is providing also the Mission Director for the LEOP through spaceopal. 
      • And since the LEOP will be supported also from the ESOC in Darmstadt, the Flight Control Team there can also count on Telespazio VEGA spacecraft operations engineers in charge of data handling, AOCS as well as Power and Thermal. 
      • At the same time, the Telespazio VEGA GIMUS Team (Ground Infrastructure Maintenance and User Support) will provide additional support for the Ground Station Software Systems during LEOP.

      The launch will be covered via live video stream on www.esa.int.

      How Sentinel-1B keeps us busy

      ​People around the world will be looking at the next Sentinel launch, scheduled for 22 April 2016 at 23:02 CET hrs from Europe’s Spaceport in Kourou, French Guiana. Only, for different reasons: While for some teams the real work begins after the launch, for others it will represent the peak of their activities or a change of activities.

      With Telespazio VEGA Deutschland’s teams as example, many different specialists have been contributing to ESA's Sentinel-1 mission, both the A and now also the B satellite in the areas of Ground Segment Systems, Systems Engineering and ICT.

      Sentinel: A good mission to work on

      Over the past months, a team from Telespazio VEGA has been preparing the necessary ICT infrastructure at the European Space Operations Centre (ESA/ESOC) in Darmstadt, Germany, needed for the Sentinel-1B launch and the Launch-and-Early-Orbit-Phase which follows. After its completion, the team will continue their “every day” job: Ensuring smooth routine operations.

      On the other hand, for the Telespazio VEGA team behind a core element of the ground segment, the launch has a different significance: The team has been contributing to the development of the Sentinel-1 Payload Data Ground Segment for ESA already much earlier; the two core subsystems – the PDGS Monitoring and Reporting (PMR) and the PDGS Resource Monitoring, Alarm and Control (RMA) – have already been deployed at seven Sentinel-1 Stations and have been operational ever since the Sentinel-1A launch in 3rd April 2014. ESA's Sentinel satellite, which will be joining its identical twin, can rely on the existing systems and trained teams onsite to fulfil its mission.

      The teams that are probably most excited about the launch, are those located at ESOC, such as the Flight Control Team or Ground Operations Teams that are partly Telespazio VEGA staff - – under the overall leadership of an ESA “Flight Director”. Once launched, the real satellite will be handed over to them for the first time. They have been prepared by expert simulations officers for this “moment” and the operations, among others also by a Telespazio VEGA colleague. Of course, we hope that the simulations were realistic enough to make the transition into real operations as smooth as possible – and the perceived change will not be as noticeable.

      About Sentinel-1B and Copernicus

      The Sentinels, a new fleet of ESA satellites, are delivering a wealth of data and imagery that are central to Europe’s Copernicus programme. The first in the series, Sentinel-1, carries an advanced radar instrument to provide an all-weather, day-and-night supply of imagery of Earth’s surface.

      Agriloc User Workshop hosted by Telespazio VEGA

      ​Anyone who has ever sat on a tractor would easily get the impression that this is something like a rolling high tech control centre. Long gone are the times of rural offline romance. Nowadays, agricultural machines are not only fully automated and digitalised; they depend on a permanent connection to the internet, even in the event that 30 schoolkids would use their smartphones simultaneously in a passing bus, challenging the mobile network to the fullest.

      Into this gap steps the project agriloc, which last week has been paying a visit to Telespazio VEGA Deutschland for the first time. During this third User Workshop, requirements of big farmers, end users and experts have been discussed, who are all relying on a permanent connection to the internet, for instance to ensure accuracy of positioning to the centimetre and automatic control of the tractor.

      The tractor goes online - via satellite

      Among the participants were also those companies developing the new technology, looking for feedback from users and end users, urgently needed. In that frame, Telespazio VEGA develops a satellite modem, which can be integrated into the tractor easily. In case of a poor GSM or LTE connection, the modem will automatically come to life and take over the data transmission via satellite. During test campaigns, the driver can see which transmission path is currently used thanks to a dedicated app. The necessary uplink- and downlink bandwidth is also provided by Telespazio.

      Osman Kalden, in-house manager of this development at Telespazio VEGA, was very satisfied with the feedback received during the Workshop. ‘To us it is really important to be able to speak to the end user and to get direct feedback. It will be down to very basic questions, if the system can be used eventually. Like if the interfaces of the modem match to those of the tractor, how user friendly the system is, if the bandwidth is sufficient, how fail-safe it needs to be or what performance farmers are really expecting. These are all questions that only experts with hands-on experience can answer.’

      Thoroughly controlled - thoroughly tested

      Using a permanent internet connection and receiving more accurate positioning data, also puts John Deere, international manufacturer of agricultural vehicles, in a position, where they can improve their products. More accurate positioning data also means that the automatic control needs to be developed further. And then the question to the end user arises: how precise can and must the control achieved be? On huge agricultural surfaces eventually every centimetre and every degree of deviation counts.

      It is the duty of the German Agricultural Society (DLG), whose representatives have closely followed the Workshop, to clarify if the components can work together effectively in the end. For only if the new technology has been tested and certified successfully, it can be put on the market after the demo phase in March 2018 and can then be beneficial for many end users.

      ‘There will be many more Workshops before we have a product that is ready for serial production’, continues Osman Kalden. ‘Until that date we have to carry on developing, testing und reassuring ourselves that we are delivering the product that the customers, i.e. the farmers, need.’

      However, at the end of the Workshop the attendees were allowed leaving their area of expertise for a moment to take a guided tour through ESOC, the European Space Operations Centre nearby. And also there they found experts on accurate navigation; for example on Earth but also when it comes to journeys to distant comets.
