VP9, BERMUDA on Satellites

VP9, BERMUDA. Chris, KG6CIH, will be active as KG6CIH/VP9 from Bermuda
(NA-005) between March 8-12th. Activity will be holiday style in addition
to also checking out the island. He will be splitting radio time with a
friend (David/WH6DSN was mentioned by another source). They will be focused
on SSB operations on the main bands (80/40/20 meters, 15 meters if pro-
pagation is good, 160m if antenna works), and maybe some satellite contacts
too. QSL will primarily be via LoTW, but if they get enough contacts, they
will consider printing up special cards.

GOLF-TEE and GOLF-1 Selected for NASA’s CubeSat Launch Initiative

On March 2, 2018, NASA announced the ninth round of selections for the
CubeSat Launch Initiative (CSLI). The first two AMSAT GOLF CubeSats,
GOLF-TEE and GOLF-1, were among the 21 missions recommended for
selection.

AMSAT must negotiate and execute a Cooperative Research and
Development Agreement (CRADA) with NASA for each project to finalize
selection. NASA anticipates a sufficient number of launch
opportunities but does not guarantee that all recommended payloads
will be launched.

GOLF-TEE (Technology Evaluation Environment) will serve as a rapidly
deployable Low Earth Orbit (LEO) testbed for technologies necessary
for a successful CubeSat mission to a wide variety of orbits.

AMSAT Vice-President Engineering Jerry Buxton, N0JY, said “The
GOLF-TEE project tees off the next phase of our CubeSat program.
GOLF-TEE provides AMSAT hardware and knowledge for Attitude
Determination and Control (ADAC) capability and the opportunity to
develop a 3U spaceframe with deployable solar panels that can be used
in LEO or HEO missions, two of the major systems required in future
GOLF and HEO missions.” Ragnarok Industries developed the attitude
control system for the Lunar Heimdallr 6U CubeSat, a NASA Cube Quest
Challenge finalist.

GOLF-TEE provides the opportunity for rapid deployment and on orbit
testing of the AMSAT’s Advanced Satellite Communications and
Exploration of New Technology (ASCENT) program’s technology, including
radiation tolerant transponder and Integrated Housekeeping Unit (IHU)
technologies that will lead the way for low cost commercial
off-the-shelf (COTS) systems that can function in the MEO and HEO
radiation environments. GOLF-TEE will also carry a Fox-1E design V/u
linear transponder and RadFx (Radiation Effects) experiment for
Vanderbilt University.

GOLF-TEE and the GOLF program will provide for the development of
“Five and Dime” Field-Programmable Gate Array Software Defined Radio
(FPGA SDR) transponders for use on a variety of missions and orbits.

The target date for launch of GOLF-TEE is 4Q 2019.

GOLF-1 will serve as a follow-on mission, also to LEO. Launch is
targeted for 2020-2021.

GOLF-1 will require a de-orbiting plan that is in compliance with
NASA's NPR 8715.6 NASA Procedural Requirements for Limiting Orbital
Debris in order to be manifested on a launch, due to the high altitude
AMSAT has requested.

Please consider a donation to the AMSAT GOLF program for development,
construction, and testing of the GOLF-TEE and GOLF-1 CubeSats. Donate

Rare Grid Rover Activation Planned on Pacific Coast

Heads up AMSAT enthusiasts. Billy Blue, KM6NJL, plans to head to
Humboldt County, California March 16-19. Billy says, "Depending
on schedule and terrain and activities I'm going to try to work
from CM89, CN70, CN80, CN71 and CN81 or the borders of these
grids. Unfortunately I won't be heading further east."

Satellite 101 Wiki Released by IIT Bombay Student Satellite Project

Members of the Pratham satellite team, the first student satellite
of IIT Bombay Student Satellite Project (IITBSSP), have created the
Satellite 101 Wiki as a part of a social goal of spreading knowledge
and enthusiasm related to satellite and space technology among
various aspiring students and universities across the globe.

The Wiki discusses:

+ Starting a Student Satellite Project
   - Building the Team
   - Planning the mission and finalizing the Payload
   - Obtaining the required Infrastructure
+ Subsystems within a Satellite
   - Payload Subsystem
   - Communications Subsystem
   - Electrical Subsystem
   - Attitude Determination and Control Subsystem
   - Mechanical Subsystem

Rules for AMSAT Awards updated

A few months ago we added Washington, DC counting the same as a state.
Today, we continued to align our awards with the ARRL. Our rules stated
contacts had to be made within 25 miles or 40 kilometers from your home
location. We have now amended the rules to read within 50 miles or 80
kilometers. This should be more beneficial for those that have moved to
a new QTH.

BIRDS-2 CubeSat Constellation Includes 145.825 MHz Digipeater

The BIRDS-2 CubeSat constellation developed at Japan's Kyushu
Institute of Technology includes three 1U CubeSats:

+ BHUTAN-1
+ MAYA-1
+ UiTMSAT-1

All CubeSats in BIRDS-2 constellation have identical designs and
utilize the same radio frequencies. They are planned for release
from the ISS together in 2018.

The primary mission of BIRDS-2 CubeSat constellation is to provide
digital message relay service to the amateur radio community by means
of an APRS digipeater onboard. The APRS digipeater onboard BIRDS-2
CubeSats will use 145.825 MHz for both receive and transmit.

145.825MHz is a standard frequency used by other satellites such
as ARISS and LAPAN-A2.

Another mission of the BIRDS-2 CubeSat constellation is to demon-
strate a store-and-forward (S&F) system. In this mission, a goal
is to investigate technical challenges through experiments on
appropriate data format, multiple access scheme, file-handling
protocol while complying with limited operational time and power
constraints.

Another interesting application of BIRDS-2 CubeSat S&F system is
for the satellites to collect data from remote ground sensors,
store them onboard and download them to the different BIRDS-2
ground stations network.

Further, students of Kyushu Institute of Technology will use BIRDS-2
CubeSat constellation to enhance research and experiment in the
fields of single latch-up event detection, magnetic field measurements
using a COTS anisotropic magnetometer, and flight testing of a COTS GPS
chip which can be used for future CubeSat missions if proven effective.

Students will also explore a passive attitude stabilization mechanism
consisting of magnets and hysteresis dampers for proper orientation of
camera on a CubeSat. All measurements and image data will be shared
with the public on BIRDS-2 project website.

Moveover, BIRDS-2 CubeSat constellation will expand amateur radio
communication experiment on the operation of CubeSat constellation
via a network of UHF/VHF amateur radio ground stations (started in
BIRDS-1 CubeSat constellation project). All the above missions are
envisioned to promote awareness of amateur radio communication and
amateur satellites among the general public and students, especially
in the participating nations of BIRDS-2 Project: Bhutan, Malaysia,
Philippines, and Japan. Planning a deployment from the ISS in 2018.

The IARU has coordinated a downlink frequency of 437.375 MHz and
for APRS uplink/downlink 145.825 MHz. The IARU detailed pages are
as noted:

BHUTAN-1
