Request for Special Temporary Authority
Virgin Orbit, LLC
File Number:

Explanation of Experiment:
Virgin Orbit LLC (“Virgin Orbit”) is requesting “Special Temporary Authority (STA)” to operate an S-Band
Transmitter in 2200-2290 MHz band. The request is for the ability to sweep across the 2200-2290MHz
band. Virgin Orbit is designing a satellite launch vehicle (“Launcher One”) that will be air launched from a
modified 747 airplane (“Cosmic Girl”). The purpose of requesting an STA license is to analyze the effects
of Launcher One’s S-Band Telemetry transmitter on 747 radios.
Frequencies Requested
2200-2290 MHz
Table 1: Frequencies requested

S-Band transmitter will be turned on along with 747 radios and the performance of all the radios will be
measured. Antennas different from the one listed in Table 2 could be used for this test. The output power
of the transmitter will be adjusted so as not to exceed the EIRP listed in Table 2 regardless of which
antenna is used.

Virgin Orbit is requesting a license to run the test at Long Beach Airport. Testing will be performed either
inside a hangar or in an open area. All testing will be performed on the ground, the aircraft will not be
flown during this test.

Testing could be conducted anytime between Aug 7th, 2018 and Feb 5th, 2019. The test will take a few
days to complete, S-Band Transmitter will be turned on for a few hours every day during the test. This test
might not be performed on consecutive days and testing could be scattered over a period of six months.
The transmitter will not be turned on without prior coordination with DoD Western Area Frequency
Coordinator (WAFC).
