Subject:            Vector Launch Inc. Experimental STA Application for
                    Vector-R Series B 0003 Launch Vehicle - Amendment

Vector is pleased to provide this Amendment to our STA request, 0162-EX STA-2018. This update
provides minor clarifications to the original submission. An updated data table, REF3, has been
uploaded to the OET ELS application website.

This application applies to a single, low altitude (< 3000 m), demonstration launch of our Vector-R
launch vehicle. The STA requests telemetry downlink from the vehicle only; no transmissions will be
made from the ground to the vehicle.

A summary of the STA application changes (REF3 data table) follows:

    •     Reduced transmitter output power to 10 W maximum.
    •     Updated necessary bandwidth calculation.
    •     Updated emission designators.
    •     Corrected error in transmitter part numbers. Part number change related to baseband data
          interface. No impact on unit RF functionality.

This application covers a single test flight of the Vector-R B 0003 launch vehicle. The Vector-R B 0003
vehicle is a low altitude test launch required to develop the orbital launch capable Vector-R B 100X
series.

Vector will finalize the planned launch date with local area frequency managers per REF5 AFTRCC
Coordination E-mail; the E-Mail is attached to Vector’s application on the FCC OET ELS website.
Coordination will be via email and telephone. Vector will also provide an update 2-days prior to
launch and the day of launch prior to the flight. Vector has included a stop buzzer phone number in
the data table REF3. Vector will confirm the stop buzzer contact information prior to the flight.

A brief summary of Vector-R B 0003 launch follows; detailed technical data for the B 0003 series is
contained in GN-0276-VSS-001 (REF3) attached.

 Launch Date       Vehicle   Launch Site                   Comment
 March 2018        B 0003    Randsburg (Mojave) CA         Planned
 April 2018        TBD       TBD                           Additional launch opportunity TBD
 May 2018          TBD       TBD                           Additional launch opportunity TBD

The Randsburg launch site is located at 35.348°N, -117.810°W, and at an altitude of 1070 m. The test
vehicle will not exceed 3050 m (10000 ft) above the launch site.

Three downlink frequencies are requested as a worst case; one or more of the links may not be used
for the flight.

Antenna registration is provided for 3 downlinks. A single transmitter type will be used. The launch
vehicle antenna patterns are omnidirectional in azimuth. All transmitter outputs will be split to two
conformal antennas located on either side of the launch vehicle. The hemispherical patterns of the
antenna pairs create an omnidirectional pattern centered on the vehicle. All antennas are right hand
circularly polarized (RHCP).

The antenna height will vary from 5 m off the ground while on the launch pad to approximately
3050 m (10000 feet) altitude.

The transmitters are Quasonix nanoTX™ (www.quasonix.com) ; these are Commercial-Off-The-Shelf
(COTS) telemetry transmitters used extensively throughout the aerospace and space industries. The
Quasonix units employ Shaped Offset Quadrature Phase Shift Key (SOQPSK) modulation.

Vector greatly appreciates the FCC’s help on this activity, and we are fully prepared to support your
needs or questions. Please contact me as soon as possible should additional information be
required.

Thank you,
