Background - Development Strategy
Background:➢ In (2006) start the decision to create the NANOSATC-BR Program
and in (2008) the development of the NANOSATC-BR1 Mission as a 1U CubeSat
➢ Many papers and presentations by the students since then
➢ First missions suggested by INPE scientists
➢ Work for the NANOSATC-BR Program start in 2009
Development strategy:➢ To develop the mission rather than the platform
➢ Start with payload development, software, AIT and operation
➢ Re-engineering to develop the platform subsystems
➢ To bring technology from abroad and incorporate it through the industry – joint ventures
➢ To create an industry in Brazil for this class of satellite
NANOSATC-BR – NCBR
Capacity Building
The major objective of the INPE-UFSM’s NCBR Program is to perform a
Specialized Human Resource Capacity Building Program through the
training of UFSM’s undergraduate and former students
Capacity a new generation of scientists, engineers and researchers
engineering and computing sciences through a CubeSat Program
Approximate the Brazilian Space Program to Universities, such as:
UFSM, UFRGS, UFRN, UFABC, UFMG and USP
Therefore, the Program provides hands-on training and learning with
Aerospace Engineering & Technologies and Space Weather issues
Training of the students, at INPE and at the Brazilian space industries as
well, as at universities and space industries abroad: TU - Berlin, University of Wurzburg and DLR in Bremen in Germany

NANOSATC-BR
Current Engineering Research
Students from several Engineering Courses at UFSM
currently perform Research and Simulation at the
CRCRS/COCRE/INPE-MCTIC in numerous subsystems and
topics, such as:
➢ Thermal Subsystem of Spacecrafts
➢ Structural and Mechanical Analysis
➢ Orbital Analysis and Flight Performance
➢ Development of Electronic Devices
➢ Protection Strategies for Solar Events caused by the Space Weather
Number of Students in the Program
➢ The main objective of the
NANOSATC-BR Program is the Capacity
Building, which happens through the
training of undergraduate students in
their respective areas in UFSM
Aerospace, Electrical, and Mechanical
Engineering
➢ An essential quality of this Program
is the close participation of students,
teachers, and researchers for the
development of activities focused on
excellence and results
➢ 34 (thirty-four) students with a
technical background and from various
undergraduate courses participated
directly in researches related to satellite
technology in the Program
Works published and participation in
Congresses
➢The academic work produced by the students includes good engineering practices and
techniques, with several publications in national and international congresses as well as
participation in workshops, all directly related to the Program’s activities
The NCBR1 and NCBR2
Engineering Model Platforms
The NCBR1, 1U and NCBR2, 2U
They have name and up and down frequencies link determined by
The International Amateur Radio Union – IARU, in 2011
NANOSATC-BR MISSIONS
NCBR1 - Science Mission
➢ The first Brazilian 1U - CubeSat scientific satellite, the
NANOSATC-BR1, is a 10x10x11.3 cm cube, weighing 0,965 kg
Earth Magnetic Field intensity measurements
South American Magnetic Anomaly – SAMA
XEN-1210 is a three-axis magnetometer with a resolution of 15nT
from the Dutch company XI - Xensor Integration (www.xensor.nl)
Only one payload circuit board with scientific and
technological payloads
NCBR1 - CURRENT SITUATION
➢ The NANOSATC-BR1 was launched on June 19th, 2014 as a tertiary
payload by ISIS in the event ISILAUNCH 07, by a DNEPR, at Yasny
Launching Base, Donbarovsky Region, Russia
➢ All payloads and subsystems, except the batteries in the power
subsystem continue to operate normally
➢ The battery can no longer hold electric charge because it was damaged
by magnetic solar storms in September-October 2014
➢ Today the NANOSATC-BR1 can transmit only when it is in sight by
the Sun
➢ The World Amateur Radio Network is currently providing NCBR1 data

NCBR2 - Current Situation - I
➢The NANOSATC-BR2 or NCBR2, is a 2U CubeSat, (10x10x22.6 cm), has
three major objectives: Capacity Building, Scientific Mission and
Technological Mission development.
➢The Scientific Mission is to monitor the Earth's Ionosphere and Magnetic
Field, with a Langmuir probe and a XEN-1210 magnetometer.
To finalize the NCBR2 it is necessary to do the following tasks:
➢- SDATF - Attitude Determination System tolerant to failure - First Brazilian
System Attitude Determination, with triple redundancy, presently in integration
and testing with the NCBR2 - EM platform;
➢- Langmuir Probe - Delivered for testing and integration with the NCBR2 - EM
platform and the onboard software - OBDH;
➢Store Forward Communication Package – software experiment, developed
by amateur radio communication from the Radio Amateur Satellite Corporation -
Brazil (AMSAT-BR) and SP-LABRE.
➢- CubeSat board with three experiments: FPGA-UFRGS; Magnetometer; IC -
SMDH/UFSM, first unit already delivered in Dec. 2017.
➢The entire platform flight software was developed in Brazil, by researchers and
engineers from INPE/MCTIC, already working in this area (Determination & Attitude
Control and Data Management).
➢The Control Law for the control software has also been developed in Brazil.
➢The Program received funding from the Brazilian Space Agency (AEB) through
UFSM-FATEC on May 2018 and managed to hire the launch of NANOSATC-BR2
on July 2019 alongside with ISIS.
➢Likewise NANOSATC-BR1 and other CubeSats projects, NANOSATC-BR2 will be
launched in a piggyback release as a tertiary cargo by the beginning of 2020 by a
Soyuz launch vehicle, operated by Roscosmos, of Russia.
➢The satellite’s future operation in orbit and tracking is under the responsibility of
the Control and Tracking Team of the NANOSATC-BR Program.
NCBR2 - Current Situation - II
NANOSATC-BR3 & NANOSATC-BR4:
Current Situation
The Engineering Models of both CubeSats
NANOSATC-BR1 & NANOSATC-BR2
are set to become the next Program satellites:
NANOSATC-BR3, (NCBR3) & NANOSATC-BR4, (NCBR4)
Both future payloads and upcoming scientific missions will be discussed with
researchers and engineers from the INPE/MCTIC, UFSM, and other Brazilian
universities.
Future missions of the NANOSATC-BR Program represent the continuity of
the Projects and the beginning of other Aerospace Programs in Southern Brazil
for the next decade.
NCBR3 - CURRENT SITUATION
➢The NCBR1 Engineering Model, in the near future, will become the
NANOSATC-BR3 - 1U CubeSat, which is currently being studied and tested
by the students of Aerospace Engineering from UFSM at the
Laboratory of Integration and Tests for Nanosatellites (LITN):
NCBR4 - CURRENT SITUATION
➢ Furthermore, the NCBR2 Engineering Model will become the NANOSATC-BR4
- 2U CubeSat, which is currently being studied and tested by students and
Software Engineers at INPE – São José dos Campos:
Making up of the First Brazilian
INPE-UFSM
NANOSATS - CubeSats Constellation
➢The combination of the NANOSATC-BR 1 & 2 with the development of
NANOSATC-BR 3 & 4 will conceive the very first Brazilian constellation of
INPE-UFSM's small satellites, in a partnership with the
UFSM's Aerospace Engineering Course.
➢Several experiments are planned to be tested on these CubeSats in the
future, including, but not limited to low-cost smart materials, communication
algorithm between two satellites of the constellation and improvement of the
current circuits tolerant to space radiation.
➢All those experiments can be tested in the future NANOSATC-BR family.
CONCLUSIONS
➢ Since it provides to young Brazilian people contact with low cost and fast
development on Space Technology, the Brazilian:
INPE-UFSM NANOSATC-BR, Cubesat Development Program
proves to be an excellent tool for developing a new generation of scientists,
engineers and researches, in Aerospace Technologies in Brazil.
➢ Throughout the development of the Program, more than 70 (seventy) people
contributed directly for the NANOSATC-BR Projects, including researchers
and teachers from various institutions in Brazil.
➢ It is expected an increase in the Brazilian Government Agencies support and
more investments for the development of Space Technology and for new
universities initiatives, in Brazil, such as the Brazilian INPE-UFSM
NANOSATC-BR Cubesat Development Program, with its CubeSats: the
NANOSATC-BR1, NANOSATC-BR2, NANOSATC-BR3 and NANOSATC-BR4
Projects.
