The CSO-1 and CSO-2 satellites were successfully launched by Arianespace in 2018 and 2020 respectively.
Arianespace orbited CSO-1 on a Soyuz mission in December 2018 from the Guiana Space Center in French Guiana.
CSO-1 operates in an 800-kilometer sun-synchronous orbit to perform a reconnaissance mission.
CSO-2 is the second of three satellites in the CSO system, following CSO-1 which launched in December 2018.
Arianespace completed its final launch of the year on 2018-12-19 by sending the French spy satellite CSO-1 into orbit on a Soyuz ST-A rocket.
Airbus Defence and Space was the prime contractor building the 3,565-kilogram CSO-1 satellite.
The 2018-12-19 CSO-1 launch was delayed by one day due to high-altitude winds above the Guiana Space Center.
The CSO-1 launch took place at 11:37 a.m. Eastern and satellite separation occurred one hour later.
CSO-1 will operate in an 800-kilometer sun-synchronous orbit.
Arianespace scheduled a Soyuz mission in the weeks after 2018-12-04 to launch CSO-1, a French military reconnaissance satellite, as its final launch of the year.
