Introduction
Astra Space Inc. is developing an orbital launch vehicle. The rocket has successfully launched from
Kodiak, AK under an FAA launch license.

The purpose of this application is to obtain a long term license to test the rocket at test sites in
California. Astra will be producing several development rockets over the next year and would like to do
development testing by radiating over the air to our ground infrastructure.

Locations
There are 3 possible locations for Astra to do its testing

     1. Orion. This is at the Astra facility in Alameda. Several rockets will be tested outside in a vertical
        position over the next 2 years.
     2. Nimitz. This is the preferred location of the Astra static fire tests. In these tests the rocket will
        be fueled and a short duration firing will take place. Over the air telemetry is required for this
        testing.
     3. Castle. This is a location at the Castle Airport in Atwater, California. This is a possible alternate
        or back up location to the Nimitz test site.

Technical Details
The launch vehicle is rather short. The external antennas are 9.6 meters above ground when the rocket
is vertical on its launch stool. The antennas are located along a ring and driven in pairs, for a semi-omni-
directional pattern.

The “transmitter” consists of a Quasonix nanoTX transmitter and supporting circuitry, such as a
telemetry encoder, output protection, and a switch matrix. The nanoTX model is capable of up to 10W


maximum RF power. The rocket will contain two (2) transmitters, each identical. Each transmitter has a
number of rates that it will use.

The two frequencies we wish to use are 2211 MHz and 2215 MHz. Our modulation scheme is PCM/FM.
The maximum baud rate that will be used is 4Mbps. The 2211 MHz carrier will have a baud rate that
varies between 256 kbps and 2 Mbps. On the other hand, the 2215 MHz carrier will always be operated
at 4 Mbps.
