For many years, two DSL lines have been used as media for inter­net con­nec­tion at ROSA. But since longer time, the capa­city became a bot­tle­neck for trans­fer­ing data from the six obser­vat­or­ies. New 25M/​60M sensors and faster optics cre­ated data volumes the two DSL lines (1Mbit upload) could not handle any­more. Since fiberop­tic con­nec­tions are not avail­able at this time, the ROSA mem­bers decided to swal­low the toad and we ordered a Starlink antenna. Installed dur­ing my ser­vice mis­sion in Feb­ru­ary, we have now more then ten times faster upload (between 10Mbit and 20Mbit) with about the same latency like the DSL lines. The exper­i­ence regard­ing avail­ab­il­ity is excel­lent in the last two months. With some addi­tion­al con­fig­ur­a­tion, we are even able to run our VPN con­nec­tion over Starlink.

About Me

Hello, my name is Martin Rusterholz. I’m a Swiss amateur astrophotographer living near Zurich, the biggest town in Switzerland. My interest in astronomy started when I was 16. At that time, I built my first Newtonian telescope and mount. I studied physics at the Swiss Federal Institute of Technology (ETH) which was the only study including at least some aspects of astronomy and astrophysics. “Looking at the nights sky is an experience touching everybody deeply inside, something common to all human beings independent to the language spoken by the individuals”. Deep-sky astrophotography is my passion.
