The spacecraft will equip 140 LEDs in three different colors (red, green, blue) on all its six faces. The LED boards will be commanded to flash to reach an apparent magnitude from ground between 13 and 8 (depending on the elevation angle of the observations). Besides the payload demonstration, the LED observations are aimed at three different objectives:<\/p>\n<ul>\n<li>to allow orbit determination (i.e. the retrieval of the orbital elements and the determination of the &#8220;trajectory&#8221; of the satellite in orbit) from astrometric measurements;<\/li>\n<li>to allow attitude reconstruction (i.e. the reconstruction of how the satellite &#8220;tumbles&#8221; while in orbit) through the pattern and color recognition of the flashes<\/li>\n<li>to test an innovative back-up communication method based on low data rate LED flashes enconding (e.g. if satellites have a broken radio, they can flash the LEDs to transmit some of their data to ground)<\/li>\n<\/ul>\n<p>If successful, the investigation of LEDSAT could lead to a broader implementation of the LEDs on all the small satellite platforms. When they are not a primary payload, LEDs could be equipped with a very low impact on the systems budget (mass, power, energy) and by lowering the duty cycle for matching with the operational plans.<\/p>\n<p>&nbsp;<\/p>\n<p>[\/et_pb_text][et_pb_divider color=&#8221;#ffffff&#8221;
