Space Environment Technologies announces the release of the JB2008 thermospheric density model
LOS ANGELES, CALIFORNIA – Space Environment Technologies announces the release of the JB2008 thermospheric density model. New solar indices, Dst/DTC, and Ap data drive the model. JB2006/JB2008 are important for analysis and operational uses. The same indices (historical values only) up to 60 days prior to the current epoch are available at the JB2008 web site. However, historical values are not sufficient to provide the accuracy and fidelity needed for LEO satellite operations, especially during active solar conditions. Up-to-date indices are important for mission critical activities such as achieving orbit determination precision, debris and collision avoidance maneuvers, reentry planning, and orbit management including propellant management.
