             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.",
