ELSA-d Target - The Mission

SSTL is supplying a "Target" satellite and avionics for ASTROSCALE's inaugral ELSA-d mission, which will simulate capture of orbital debris and is designed to validate key technologies for end-of-life spacecraft retrieval and disposal services.  

The ELSA-d mission comprises of a "Chaser" satellite and the Target satellite, and will demonstrate key technologies necessary for orbital debris removal such as rendezvous and docking and proximity operations.  ASTROSCALE are designing and manufacturing the Chaser in Tokyo using avionics from SSTL.  

The Target and the Chaser will be attached for launch and deorbit, but while on-orbit, will be deployed in a series of three increasingly complex separation and capture manoeuvres using rendezvous and docking algorithms. A docking plate with optical markers will be attached to the Target, allowing the Chaser to identify and estimate attitude during the docking. 

SSTL’s Target satellite incorporates S Band communications, GPS positioning, a 3-axis control system and laser retro-reflector. A variant of the SSTL-42 constellation platform family designed for operational missions in the 5kg-100kg range, it will also fly an HD camera and lighting to record the capture sequences during eclipse.
