1. A system comprising:
one or more computing device processors; and
one or more computing device memories, coupled to the one or more computing device processors, the one or more computing device memories storing instructions executed by the one or more computing device processors, wherein the instructions are configured to:
collect a first set of measured information from a plurality of space vehicles and a second set of measured information from a reference space vehicle;
derive, using the first set of measured information, an affine system for each of the space vehicles;
derive, using the first set of measured information and the second set of measured information, a set of physical distance metrics between each of the space vehicles and the reference space vehicle;
identify, using the set of physical distance metrics, a set of space vehicles having a physical distance metric below a threshold;
upon identifying the set of space vehicles, perform a similarity analysis for each of the identifier set of space vehicles producing a set of intercalibration parameters for each of the identified set of space vehicles;
apply the set of intercalibration parameters to the affine system of each of the identified set of space vehicles producing a set of affine information; and
form, using the set of affine information, an ensemble product defining calibrated sensor information from the space vehicles.
