The satellite is a 2.1m dia 4.5m high cylinder with antenna deployed and AKM attached. The main bus is 2.1 dia 1.6m high, with antenna but without AKM it is 3.0m high. The FG-36 AKM is a cylinder-cone 1.5m high 1.0m dia and 729 kg full 70? empty, leaving a BOL mass for FY-2 of 651 kg. AKM Burn time is 43s, Isp 289.0. After the AKM fires and is ejected, an imager cover is also ejected into near-GEO.
