Request for Special Temporary Authority
Virgin Orbit, LLC

Explanation of Experiment:
Virgin Orbit LLC (“Virgin Orbit”) is requesting “Special Temporary Authority (STA)” to operate an S-Band
Transmitter at 2287.5MHz. If 2287.5 MHz is unavailable Virgin Orbit is open to any frequency within 2200-
2290MHz band.

The objective of the experiment is the following.

     -     Receive Telemetry data from Launcher One’s S-Band Transmitter during Launcher One’s drop test
           (Drop test rocket will not be fueled or powered).
     -     Test the RF link between Launcher One’s S-Band telemetry transmitter and 747 aircraft’s S-Band
           receiver & receive only Long Beach Ground Station.

747 aircraft will take-off from either one of the two airports shown in Figure 3 with Launcher One rocket
in captive carry. S-Band transmitter will be turned on in R2508, R2515, W289S and W291 airspaces (shown
in Figure 2). Virgin Orbit is coordinating the use of the above mentioned airspaces with the concerned
authorities. R2515 is being considered for rocket drop and we are coordinating with the concerned
authorities.

Two different data rates will be tested at the same assigned frequency. Launcher One transmitter will only
be turned on within the requested areas. Virgin Orbit will have the ability to turn the Launcher One
transmitter on and off from the 747 Aircraft while in captive carry. The 747 might be flown to a maximum
altitude of up to 40,000 ft. The transmitter will be turned on, at the ground at requested airport locations
(Figure 3) for RF checkouts.

We plan to start the testing by July 23rd 2018, and the aircraft is expected to be flown multiple times
during the six month period after the STA license is granted.

The S-Band Transmitter will not be turned on without prior co-ordination with DoD WAFC. Exact date and
time of the testing will be flexible based on DoD coordination.
