SATEX I was supposed to be the first satellite developed entirely by Mexico . It was developed in 2002 under the direction of Enrique Pacheco from CICESE in collaboration with the Instituto Politécnico Nacional and UNAM .

For as microsatellite designed (about 50 kg) SATEX among other novel should laser - Telemetry be developed that SATEX Optical Payload (SOP). It should serve to exchange data with ground stations with uplinks and downlinks for wavelengths of 530 and 830 nm . Novel software should be used to optimize signal attenuation and BER . The other systems of the satellite should also be miniaturized.


The story of the SATEX program began in 1993 with the purchase of two satellites from Hughes Communications as part of a technology transfer by the former Instituto Mexicano de Comunicaciones (IMC - Mexican Institute of Communications) and the collaboration with Arianespace to bring the satellites into orbit. This purchase included training courses for Mexican scientists in France and the USA.

After some institutional difficulties, the program did not resume intensively until 1999, but ended in 2002. The earlier Mexican satellites types Morelos 1 and 2 (approx. 1985–95) and Solidaridad 1 and 2 (from 1993), on the other hand, were commercial communication satellites and were created in cooperation with foreign organizations.
