We estimate the main systematic effects relevant in a mission to test and
characterize the Pioneer anomaly through the flight formation concept, by
launching probing spheres from a mother spacecraft and tracking their motion
via laser ranging.Comment: 9 pages, 1 table, 2 figures; based on a talk presented by one of us
(O.B.) at the 2nd. Pioneer Anomaly Group Meeting at the International Space
Science Institute, 19-23 February 200
