Approach for Passive Parts Procurement for Space in New Space Scenario

During the last decade, more than 1,480 satellites were put in orbit. However, the current forecast for the next 10 years is exceeding the number of 9,000 satellites. Many of these satellites will be based in the so called “New Space” concept, where an emerging demand of solutions based in lower cost, faster development time and higher technical performance exists. Under this environment, it is required to identify, not only technologies but also validation approaches capable to generate the required confidence and reliability for the intended applications.

Not much focus on passive parts has been placed under this new approach. Partially because the cost of some of these parts (i.e. resistors, capacitors) is lower with respect to other families. Additionally, some passive families (i.e. relays, connectors) where the cost is much higher are also considered critical from the reliability point of view.

Considering all the above, it is required to consider and adopt a new process for product selection and validation steps ensuring we are meeting the defined targets (low cost, lower delivery time and higher performance) without a significant compromise of the final product reliability.

During this paper two main topics will be addressed:

  1. When the selection of non hi-rel passive parts makes sense from the cost and performance point of view.
  2. How making those non hi-rel parts a safe choice by the usage of validation techniques allowing gaining the
    required confidence in the reliability of the parts.
