abstract = "Brazil has launched a few cubesats so far. Both through
universities as well as through space research institutes and its
Space Agency. There is a growing interest in the country for this
type of satellite due to its low and feasible costs for these
institutions, as well for the increasing number of possibilities
with its use. The advantages of its use for science and
educational purposes is not questioned any more in a changing
scenario, as was the case in the world in general. However, so
far, all these missions were developed with government funds. The
challenge now is to transfer this technology and application to
the private sector. The mission here described is the first in the
country developed by a private company in cooperation with the
public R\&D space sector for the payload. In the process it also
creates a production chain with other companies for the
development of part of its subsystems and software. A few of them
(HorusEye, USIPED) are new in the space field although with large
experience in other micro electronics and precision mechanics
applications. These subsystems are the attitude determination and
control, the EPS and the structure. All of these with advantages
when compared with similar subsystems available in the
international cubesat market. Software is also developed by a
small company from former INPE graduate students (EMSISTI). The
OBC and the transceiver will still have to be imported due to the
larger development costs, and the limited budget for the project.
The scientific payload of the mission is an experiment for the
detection of hard X-ray and gamma ray radiation in space, possibly
from cosmic explosions such as Gamma-Ray Bursts (GRBs). This
experiment was initially conceived for a larger bus but it has
never materialized due to its costs. The number of detectors in
the payload array was significantly reduced but it will still
produce significant results for the mission PI. One exciting
possibility is the detection of electromagnetic counterparts of
gravitational wave signals detected by the LIGO/Virgo consortium.
This was not known when the larger bus was being considered for
this mission. The cubesat is a 2U with 1U fully for the payload.
CRON-1 was officially submitted to be launched in 2021 by the
first launch of VLM (Microsatellite Launch Vehicle), the small
launcher under development by the Brazilian Air Force, Brazilian
industries and DLR (German Aerospace Center). However it will be
ready to be launched by the end of 2020 and another earlier launch
alternative may be selected if it canīt be launched by VLM. The
project was selected to be funded by the S{\~a}o Paulo State
Foundation for R\&D (FAPESP) in a call from its Innovation
Program for the Small Company (PIPE) for the development of the
engineering model so far. The paper gives more information and
details about the payload and the science motivation for the
mission as well as for the subsystems developed for CRON-1.",
