Abstract
Currently, in Peru, the study of satellite images is increasing because it has the Earth observation satellite PeruSat-1. However, the cost of implementing a ground station is very high; for this reason, it is baffling that each university has its station. In the present work, the design and implementation of a low-cost portable earth station for the reception of meteorological satellite images is proposed in an automatic way, using accessible electronic devices such as Raspberry Pi 3b +, Software Defined by Radio (SDR) and an antenna double cross four dipoles, in this way encourage the study of satellite images in schools and universities. The results obtained show the viability of this project.

The design and implementation of a low-cost portable earth station for the reception of meteorological satellite images is proposed in an automatic way, using accessible electronic devices such as Raspberry Pi 3b +, Software Defined by Radio (SDR) and an antenna double cross four dipoles, in this way encourage the study of satellite images in schools and universities
In Peru, the study of satellite images is in advance with the National Centre for Operations of Satellite Images (CNOIS for its Spanish acronym) that provides the images from the PeruSat-1 Earth Observation Satellite to different public and private entities
The system receives Automatic Picture Transmission (APT) satellite images thanks to the double cross antenna of four dipoles Fig. 2, the design of the antenna is ideal for the reception of this type of signal; in addition, its components for its construction can be acquired in any hardware store [8]
Summary
In Peru, the study of satellite images is in advance with the National Centre for Operations of Satellite Images (CNOIS for its Spanish acronym) that provides the images from the PeruSat-1 Earth Observation Satellite to different public and private entities. CNOIS belong to the Peruvian Space Agency (CONIDA for its Spanish acronym for National Commission of the Aerospace Research and Development National Commission). For the use of these satellite images, the interested entities must assign two employees as representatives of the institution, who have to manage the request and reception of CNOIS products. The reception of these images is carried out by a direct link from the ground station to the PeruSat-1 [1]
