Katalog deutscher Raumfahrtakteure
catalogue deutscher Raumfahrtakteure (29 MB)

We are pleased to present the first edition of the catalogue of German space players (Katalog deutscher Raumfahrtakteure - KaRA). With the participation of GEOsat GmbH, the German Aerospace Center (DLR) has created the catalogue. The full range in the space sector of federal and state authorities, universities, technical colleges, non-university research institutions, associations, networks and associations, companies, incubators and media is evident in the catalogue.

KaRA is primarily aimed at politicians, multipliers and cooperation partners as well as at non-aviation science and industry. The catalogue is intended to clearly illustrate the activities and competencies of the German space actors.


The GPS Internal Navigation Time Scale “GPS Time” is based on the weighted average of GPS satellites and ground station clocks.  GPS Time is used for user navigation solutions.  A nanosecond error in GPS Time can equate to one foot of position (ranging) error.  The WN parameter is provided via a ten (10) bit parameter–or “counter.”The valid range of values for the WN parameter is 0 to 1023 (or 1024 total values).  The WN parameter is incremented by one each week. At the end of the 1024thweek, the counter experiences a rollover (resets) to 0.  Each WN rollover event defines a new GPS Time Epoch.  The WN value is referenced to the start of the current GPS Time Epoch.  The last WN rollover was August 21, 1999.  GPS Time is currently in the second Epoch.  The next WN rollover is April 6, 2019.

The GEOsat recommends that you, regardless of the manufacturer, play a current firmware to the GNSS receivers to take into account the upcoming GPS week rollover.

If you need assistance for this, we will be happy to assist you at any time.


On 11 February 2019, the four satellites launched from the European spaceport in Kourou, French Guiana, on July 25 2018, were put into service following the completion of the relevant commissioning activities. This means that the Galileo constellation is now providing services with 22 satellites.

“This is another important milestone for Galileo and the European Union. Each satellite that is commissioned brings us closer to our full operating capacity. More satellites in operation mean better coverage and more availability, which translates into increased accuracy and better services for users,” European GNSS Agency (GSA) Executive Director Carlo des Dorides said. “The entry into service of the latest four satellites will boost Galileo service provision around the world.”

Thanks to the addition of four more satellites to the Galileo constellation, users will be able to reap the high accuracy benefits of multi-constellation capacity, but it goes further than that, according to Rodrigo da Costa, Galileo Services Programme Manager at the GSA.

The new GEOsat-receivers are already using the signals from the Galileo satellites.

innovative through research


The Stifterverband für die Deutsche Wissenschaft pays tribute to the GEOsat for their long lasting and successful research activity with the label "innovative through research".
Since founding the GEOsat GmbH in 1985 we engage in numerous research projects with the focus on GNSS, telematics, sensor technology and geographic information. Our versatile potential of innovation is the basis for the development of new products and services, always close to the project and to the customers.
Stifterverband is a joint initiative started in 1920 by companies and foundations – the only one in Germany to be devoted entirely to consulting, networking and promoting improvements in the fields of education, science and innovation.

The adjacent current news from the local press WAZ shows it again, modern telematics helps in the protection against theft or in its solution. The most up-to-date telematics system from our company GEObox Smart, offers a variety of functions that are suitable for alarm messages, among other things:

  • Alarm when leaving a defined area (geofence),
  • Alarm Alarm when moving outside a defined time window,
  • Alarm when moving the vehicle (even without GPS),
  • Alarm when the on-board power is disconnected.

The value added of our system GEObox smart goes far beyond theft protection. Should you need any further information, please do not hesitate to contact us.
