190“Space-Based Infrared System–Geostationary Orbit”04 satellite orbit position determination;
FromDecember6to11, 2015, the “Space-Based Infrared System–Geostationary Orbit”04 satellite began propellant loading, and onJanuary7, 2016, the payload fairing was completed, with a planned launch onJanuary19, 2016, targeting an orbit with a perigee of185.2 kilometers, an apogee of35785 kilometers, and an inclination of23.29 degrees to the geosynchronous transfer orbit.

191“Space-Based Infrared System–Geostationary Orbit”04 satellite received its official designation;
However, onJanuary19, 2016, at1932 minutes, the “Atlas V5” launch vehicle encountered a technical issue with a sensor in the Russian-madeRD-180 engine used in its first stage. After resolving the issue, at2023 minutes, an aircraft entered the no-fly zone near Cape Canaveral, causing the launch to be paused and reverting to a4 minute hold procedure, which resulted in the launch time exceeding the window, and the launch on the 19th was ultimately canceled.The window on the 20th was1952 minutes to2022 minutes, with the “Atlas V5”401 configurationAV-066 rocket launching from Cape Canaveral Air Force StationSLC-41 at1952 minutes onJanuary20, 2017, heading to geostationary orbit. This4536 kilogram satellite entered an orbit with a perigee of185.172 kilometers, an apogee of35821.384 kilometers, and an inclination of23.289 degrees (Lao Jun001 notes: this is basically consistent with the target orbit position, indicating that American space technology is part of a precise scientific system). The satellite was designatedUSA-273 and received the North American Aerospace Defense Command space object number41937.
