                          Exhibit 1: Akash Mission Description

1. Introduction
Akash Systems Inc. (referred to as “Akash”) is on a mission to improve the spectral efficiency of
satellite communications systems with its patented GaN-on-Diamond technology. Founded in January
2016, Akash is composed of a veteran team of GaN and satellite innovators, and is headquartered in
San Francisco, CA with an additional office in Dallas, TX.

Akash has incorporated its GaN-on-Diamond technology with a flight-proven software defined radio
(SDR) into a compact form factor, and seeks authority to test its GaN Transmitter technology on a 12U
CubeSat called “MCNAIR”.

2. Technical System Description
On October 1, 2019, MCNAIR will be launched from New Zealand’s Mahia Peninsula on a Rocketlab
Electron rocket to a sun-synchronous orbit targeted for an altitude of 500 km, and an inclination of
97.8 degrees. The demonstration is intended to begin on October 1, 2019 and end on April 1, 2020, but
with CubeSat missions the launch window could slip in time. All emissions will cease after the six-
month demonstration is complete

MCNAIR is a 12U CubeSat that measures 23.9 cm by 22.9 cm by 36.6 cm stowed and has a mass of
19.9 kg. MCNAIR consists of an Akash GaN Transmitter (parabolic antenna), a S-band SDR (patch
antenna) for telemetry and telecommand (TT&C), a spacecraft flight computer, avionics and GNC
equipment, power system components, and 2 solar panels (one per side), each measuring 30 cm x 40
cm. There is no propulsion on-board, and based off NASA’s Orbital Debris Assessment (ODA) software
the orbital lifetime is 2.075 years for a 500 km 97.8 degree orbit. As previously mentioned, with
CubeSat missions, there is often a chance that a launch window can shift, and that the ultimate
altitude can vary slightly. The range of possible sun-synchronous altitudes for MCNAIR varies from
400 km – 600 km (inclination of 97.8 +/- 1.5 degrees). Orbital debris analyses have been run for the
feasible altitudes, and in each scenario all requirements are met. See the ODA Report (ODAR) ,
provided in Exhibit 6, for more information.

The Akash GaN Transmitter will downlink pre-configured test data over a single 1.2 GHz bandwidth
channel in Ka-band (19.0 - 20.2 GHz) to a 13.2 meter ES in Dongara, Western Australia. Ka-band
transmissions will occur in both RHCP and LHCP to maximize spectral efficiency. A summary of the
frequencies and bandwidths used in this demonstration is provided in Table 1.

Akash will operate on a non-protected and non-interference basis. Akash is aware of the MSS
allocation in Ka-band, and has conducted preliminary, informal coordination with Iridium. Akash is
also aware of the US334 footnote and has initiated discussions with NTIA to ensure that the
demonstration does not interfere with existing operations.

There will be no corresponding uplink to MCNAIR in Ka-band, and MCNAIR will be telecommanded
to cease all emissions when it is not in view of the Dongara ES. Passes will occur between 3-5 times a
day and each pass will have a duration of approximately 8 minutes. The Ka-band parabolic antenna
has a 3 dB beamwidth of 2.2 degrees and a gain of 36.2 dBi. As shown in the figure below, the Ka-band
downlink transmissions will comply with the relevant FCC and ITU power-flux density (PFD)
regulations.

MCNAIR’s S-band TT&C SDR will receive telecommands from and transmit telemetry to a 3.7 m
KSAT ES located in Svalbard. A total of 0.2 MHz of uplink bandwidth in the 2025 - 2110 MHz band is
required for telecommand, and a total of 2 MHz of downlink bandwidth in the 2200 - 2290 MHz band
is required for telemetry. Akash has identified the 2109.5-2109.7 MHz frequency range for uplink
telecommand transmissions and the 2286 – 2288 MHz frequency range for downlink transmissions.

3. Objectives
Simulation and ground-based lab tests have proven that the Akash GaN Transmitter is capable of
transmitting data rates as high as 14 Gbps. The primary objective of the MCNAIR is to demonstrate
record-breaking downlink spectral efficiency and data rates from low earth orbit using Akash’s GaN
Transmitter, and to qualify the transmitter in a space environment.
