LauncherOne is an expendable, launch vehicle designed to place small satellites into a wide range of Low Earth Orbits (LEO). STA License is requested to operate an S-Band Transmitter on Launcher One at 2215.5 MHz for the upcoming first launch. STA is necessary to authorize the use of S-Band transmitter for telemetry and video transmissions. The transmitter is located on 2nd stage, it will be turned on few minutes before launch and will stay ON until the end of the mission. The transmitter will also be turned on for RF checkouts at Mojave Air and Space Port. Data rate will be reduced at some point in time during the mission. Figure 1: Cosmic Girl (747) with Launcher One under the wing 747 will take-off from Mojave Air and Space Port in California with Launcher One in captive carry.
