Mission Task content Autonomous on-orbit decision-making Develop payload and mission-level autonomous software（including on-orbit distributed decision processors）and demonstrate autonomous orbital operations. The payload can operate autonomously through on-orbit data processing，and the system will autonomously perform on-orbit sharing tasks according to high-level system instructions Advanced commercial manufacturing technology Develop and implement advanced commercial manufacturing of military payloads and spacecraft platforms，with plans to use commercial off-the-shelf（COTS）-type components to develop high-speed manufacturing processes and reduce screening and acceptance testing of spacecraft，thereby enabling low-cost spacecraft manufacturing LEO constellation performance demonstration Low earth orbit（LEO）demonstration validates satellite payloads. Its capabilities are comparable to current geostationary（GEO）orbit systems，enabling a combined cost of less than $6 million per satellite platform，payload，and launch Ultimate goal Develop a constellation of 60 to 200 satellites operating at an altitude of 500 to 1300 km. Data processing for the "Black Jack" payload will be done on-orbit without the support of ground segment. Constellation is able to operate without an operations center for 30 days
