Satellite de Aplicaciones Cientifico-A (SAC-A) was a small non-recoverable satellite built by the Argentinean National Commission of Space Activities (CoNAE). The satellite will test and characterize the performance of new equipment and technologies which may be used in future operational or scientific missions.

The satellite payload included a Differential Global Positioning Systems (DGPS) to provide real-time autonomous attitude measurements for the satellite, a CCD camera to perform digital space photography, Argentinean built silicon solar cells, a magnetometer to take scalar measurements of the Earth's magnetic field, and an Argentinean experiment to track endangered whale population migrations in the southern hemisphere.
