Space business is rapidly evolving towards what is usually called as “New Space”, covering smallsats to form large constellations or megaconstellations operating in multiple low Earth orbit (LEO) planes. This “New Space” tries to reach a more cost/efficiency ratio so that the monetary cost of the project is reduced as much as possible and guaranteeing its reliability.

Component engineering consists of all the activities needed to correct the components’ correct selection, adapting their characteristics to the specific project requirements. It is easy to understand that for the correct component selection is therefore indispensable the availability of a PA plan. A component selection must be made, considering all the provisions stated in the PA plan regarding design, production, planning, and testing.

Product Assurance is a key step in New Space projects where SMALL SATS is one of the protagonists; due to the relatively low maturity of the sector and COTS parts for this type of mission. The Product Assurance Plan is the first step to a successful and well-managed project, and many of the activities that will be developed during the mission will be based on this Product Assurance Plan.

Current limiting is a basic block element of any power supply. Many electronic devices are powered almost 100% of the time and are usually unattended, and therefore safety methods like current limit devices are essential to protect and improve the good performance of the equipment. In this sense, current protection is even more important in space applications, not only because of the criticality of the missions and the unavailability of repair but also because the possibility of Single Event Latch-up

When selecting non-volatile memories for space applications (such as EEPROM, Flash…), one will most likely turn to specific areas of interest for space applications, such as radiation performance, quality level, specific tests that must be performed during procurement etc. However, it is important not to forget about the basic features of non-volatile memories, which is the fact that non-volatile memories are capable of retaining the information even though the power has been switched off.

The radiation analysis is an essential document for the revision and approval of the components used within space equipment. This document includes in a single place all the information (data, assumptions and methods) and the results obtained when analyzing the radiation effects in the components used.

Power MOSFET’s are a key element of many electronic designs where high power management is needed. They are used in almost any power supply application (for example as switches). However, the fact that they are key, doesn’t mean necessarily that we have a wide number of rad-hard power MOSFET providers.
