First Earth Observation images compressed by the new FAPEC-CILLIC algorithm onboard ESA’s OPS-SAT

The European Space Agency (ESA) launched OPS-SAT on 18 December 2019 into a circular, polar orbit at 515 km altitude.OPS-SAT is a technology demonstration nanosatellite based on the cubesat standard. The satellite is only 30cm x 10cm x 10cm, but it brings powerful technology and instrumentation onboard, such as a fine Attitude Determination Control System, […]

On 25 April 2018 at 12:00 CEST, the second Gaia data release (Gaia DR2) was published. This is a major milestone in astronomy, leading to the largest and most precise multi-dimensional map of our Galaxy: it provides positions and brightness of 1.7 billion stars (also providing distances, proper motions and colours for 80% of these), […]

New FAPEC stage for tabulated text data compression

DAPCOM is about to release a new version of the FAPEC data compression software. Among its exciting new features we can find a new stage for tabulated text data, such as point clouds or CSV files. We have done some tests which reveal that FAPEC achieves the best compression ratios at a very low computing […]
