Abstract
The first two members of BRITE Constellation, TUGSAT-1/BRITE-Austria and UniBRITE were launched in February 2013, followed by the Polish and Canadian BRITE satellites. Designed for a lifetime of 2 years, the satellites are operational for more than 8 years, four times the design lifetime. This is a remarkable achievement and demonstrates that challenging scientific requirements can be met with low-cost nanosatellites based on COTS components. The presentation summarises the design of the satellites and outlines important lessons learnt from the mission. The UTIAS generic satellite bus (GNB) has proven to be a superb platform. Thermal behaviour is very good and attitude control is better than originally specified resulting in excellent science data quality. For future missions it is recommended to design the spacecraft with a larger size than 3U making thermal and mechanical design easier (the GNB is equivalent to 8U). A larger bus allows to implement more solar cells. With more power available, instruments with Peltier cooling could be used. The batteries are still in good health. Care has, however, to be taken that the batteries are never operated above 47°C and that the depth of discharge shall not exceed 15 % to avoid reduced lifetime. A good FDIR (fault detection, isolation and recovery) system is vital to avoid damages to the spacecraft if no communications with the spacecraft is temporarily unavailable. The BRITE mission has shown that strong interference, particularly in the UHF-band,exists in certain parts of the world, limiting communications. The amateur radio frequencies which have been popular in the CubeSat community can only be utilised if it is a true amateur radio mission. A future science satellite should use the coordinated S-band in up- and downlink for telemetry and telecommand, for bulk data download X-band can be considered. Flight-proven radios are available on the market.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
