At ETH Zurich\, tog ether with Swiss part- ners\, we developed a very small\, low-power multi- GNSS payload capable of precise orbit determination and timing onboard eve n the smallest satellites. On December 3\, 2018\, and April 1\, 2019\, the first two 3-unit cube satellites of the Swiss company Astrocast carrying our GNSS payload were launched. We will demonstrate the accuracy of the or bit determination and timing performed in real-time onboard the two satell ites using GPS as well as Galileo. A first valida- tion of the orbit accur acy we can reach has already been achieved by shooting with laser pulses f rom the Zimmer- wald.observatory to the tiny retro-reflectors mounted on b oth satellites.\n\nCo-sponsored by: ION-CH\n\nSpeaker(s): Prof. Markus Rot hacher\, \n\nRoom: HG D1.1\, Bldg: HG\, ETH Zürich\, Zurich\, Switzerlan d\, Switzerland LOCATION:Room: HG D1.1\, Bldg: HG\, ETH Zürich\, Zurich\, Switzerland\, S witzerland ORGANIZER:heinz_wipf@bluewin.ch SEQUENCE:0 SUMMARY:Nano-Satellites – a GNSS Payload for Orbit Determination and Timi ng URL;VALUE=URI:https://events.vtools.ieee.org/m/218616 X-ALT-DESC:Description: <br /><div class="page" title="Page 1">\n<div class ="layoutArea">\n<div class="column">\n<p><span style="font-size: 10.000000 pt\; font-family: 'ArialMT'\;">In the last years\, there has been an enorm ous increase in the number of nano satellites launched into space and cons tellations of thousands of such satellites is foreseen in the near future.
