Headline Details: The main goal of the Lucky-7 1UCubeSat is to test the first space friendly electronic spacecraft subsystems and design considerations in combination with modern COTS (Commercial Off The Shelf) electrical components leading to increased radiation tolerance within the harsh space environment as a precursor for the next generation of Deep Space CubeSat missions and serving in future also for the conquest of Mars by CubeSats/small satellites. To prove the subsystems in harsh environment, the retrograde Sun Synchronous Orbit at an altitude of 600 km passing through radiation belts was defined as a target. The satellite will contain MOSFET-Free Ultra High Efficient radiation tolerant switch mode low voltage power supply, cold redundant onboard computer with cold redundant UHF transceivers, cold redundant zero deployment torque dipole antennas, active Attitude Determination and Control Subsystem with special custom-made Ultra Low Power GPS-L1 navigation receiver and a set of high power LEDs transmitting in visible spectra (blue) to demonstrate EPS high power handling capability. Among those listed above the Digital Color camera module will be used aboard the satellite to capture the images of Earth to confirm ADCS stabilization functionality and “high” data transfer throughput capability of the custom-built FSK onboard radio. Proposing a UHF FSK downlink at variable bit rates up to 9k6. Data format information will be made available at http://www.lucky7satellite.org May launch in May 2016 together with PWsat-2 ** A downlink on 437.525 MHz has been coordinated**
Application Date: 11 Mar 2015   Freq coordination completed on 17 Jun 2015
