Small Sats Testing

New Space

ALTER works the new space through the small sats testing, improving your time to market and at a lower cost, contributing to the cost-effectiveness of the manufacturing process.

New Space has become a space revolution within the market, bringing new challenges, where small sats revolutionize how space is used. ALTER offers all equipment-level small sats testing activities that are carried out to put any spacecraft into orbit. Small satellites are spacecraft with a mass of less than 500 kg, although we can find some satellites with a lower threshold. They fall into three categories: nanosatellites with 1 to 10 kg mass, microsatellites with 10 to 100 kg, and minisatellites with a group between 100-500 kg.

Execution of Static Magnetic Field (SMF) test and PFM test campaigns. 

Neptuno is a demonstration mission by the consortium DEIMOS SPACE, DHV, and AEORUM which objective is to contribute to shipping surveillance by using Automatic Identification System (AIS) and artificial intelligence to detect anomalous navigation patterns that might be indicative of criminal activities. Neptuno includes a lighter structure made by 3D printing. Neptuno was launched on June 20th, 2021, in LEO orbit.

The European Regional Development Funds (FEDER) funded Neptuno within the Programa Operativo de Crecimiento Inteligente 2014-2020 by Spanish CDTI. It also had support from ESA for the launch phase through the GSTP FLY program.

UCA Melisa III

Universidad de Cádiz – Melisa III
Execution of an entire test campaign, including SRS, Vibration Testing, EMC Electromagnetic Compatibility and Thermal-Vacuum.

MELISA-III is an In-Orbit demonstration/Validation (IOD/IOV) experiment developed at the University of Cádiz (UCA) and selected by the European Space Agency (ESA) and the European Commission under the H2020 Programme. The technological developments in the MELISA-III experiment aim to validate a compact magnetic measurement system for its usage in future space-based gravitational wave detectors, such as the LISA mission (ESA).

The main objective of MELISA-III is the in-flight sub-milli-hertz noise characterization of a set of magnetoresistive sensors with dedicated electronic noise reduction techniques. MELISA-III will be accommodated onboard a 6-Unit CubeSat platform by ISISpace together with two other selected experiments.

SATLANTIS iSIM-170 and iSIM-90
Execution of EMC Electromagnetic Compatibility, Thermal Vacuum and Vibration Testing.

iSIM-170 and i-SIM-90 are optical payloads for small satellites with unprecedented performance. They have been fully developed by SATLANTIS. They cover VIS and NIR spectral ranges. iSIM-170 was installed on the International Space Station in 2020 and iSIM-90 will be installed in Q4 2021 also on the ISS.
