EgyptSat-A (MisrSat-2) is an earth observation satellite of the Egyptian Egypt's National Authority for Remote Sensing and Space Sciences (NARSS).
The satellite was launched into sun-synchronous orbit from the Baikonur rocket launch site on February 21, 2019 at 16:47 UTC by a Soyuz-2-1b " Fregat " launcher . Incorrect adjustment of a filling sensor in the oxygen tank of the upper stage resulted in insufficient oxidizer, which in turn led to the third stage of the rocket failing prematurely. This resulted in a track that was 60 kilometers too low, but this could be compensated for by the reserves of the Fregat-M upper stage.
EgyptSat-A is a further development of EgyptSat 2 , which was launched in April 2014 . However, this failed after less than a year due to a computer breakdown in which both the main and the reserve on-board computer failed within a few seconds. The EgyptSat-1, which was launched in 2007, had previously failed after only three years of operation.
The hexagonal, three-axis stabilized satellite is equipped with a camera that delivers a resolution of one meter panchromatic and four meters multispectral with a swath width of 1,400 km. It should provide images for military and government tasks. For the orbit maneuvers it is equipped with SPD-70 ion engines. It was built on the basis of the 559GK satellite bus from RKK Energija and has a planned lifespan of eleven years.
