Kleos' first two Patrol satellites deployed from D-Orbit Transfer vehicle
(14 Apr 2022) Kleos Space S.A. confirmed the first two Patrol Mission satellites (KSF2-C and KSF2-D) have been successfully deployed from D-Orbit's orbital transfer vehicle, ION Satellite Carrier, and contact has been established. The remaining two Patrol satellites (KSF2-A and KSF3-B) are expected to be deployed into a different orbit from the transfer vehicle in the coming weeks to establish the four satellites' formation.
D-Orbit's orbital transfer vehicle is a self-propelled satellite deployer. Carrying Kleos' four Patrol Mission satellites, it was successfully launched into a 500-km Sun synchronous orbit from Cape Canaveral in Florida aboard the SpaceX Transporter-4 mission on 1 April.
Kleos' technical team has established bi-directional communication with the KSF2-C and KSF2-D satellites, and in-orbit system commissioning has commenced. As all four satellites are deployed from the orbital transfer vehicle, satellite developer Innovative Solutions In Space (ISIPACE) will assist with Launch and Early Operation Phase (LEOP) support, including uploading and testing payload software, recalibrating the Attitude Determination and Control System (ADCS), and manoeuvring the satellites into their operational formation. Improvements to the Patrol Mission's flight software is expected to significantly reduce commissioning times.
The Patrol Mission expands Kleos' low Earth orbit constellation to 12 satellites and increases radio frequency data collection capability to 253 million km² per day. The cluster features new frequency spectrum capabilities, enabling geolocation of X-Band radar transmissions in the 8,500 -9,600 MHz range, commonly used for maritime vessel traffic control.
