The LabOSat collaboration (acronym for “Laboratory On a Satellite”) aims to increase the Technology Readiness Level (TRL) of electronic devices and components for space-borne applications. We have developed a single-board electronic platform which is able to operate in space conditions. This board harbors Devices Under Test and performs electric experiments on them. Since 2014, we have participated in six satellite missions (Satellogic small satellites) in Low Earth Orbits, in which we studied the performance of electronic devices such as resistive switching memories and dosimeters based on field-effect transistors.

In this work we present our efforts to increase the TRL of Silicon Photomultipliers (SiPMs). In early 2019 we have integrated four 6-mm SiPMs into a 40-kg satellite to study their performance in space. Each SiPM was encapsulated into individual light-tight aluminum housings, which included LEDs for excitation. The SiPMs and the LEDs are operated in DC current mode. Besides the SiPMs current and voltage measurements, the experiment also collects telemetry parameters like temperature, timestamp and orbital position.

LabOSat的合作（缩写为“卫星实验室”）旨在提高用于航天应用的电子设备和组件的技术准备水平（TRL）。我们已经开发了一种单板电子平台，能够在太空条件下运行。该评估板包含被测设备，并对其进行电学实验。自2014年以来，我们参加了近地轨道的六次卫星飞行任务（卫星小型卫星），在其中我们研究了基于场效应晶体管的电阻式开关存储器和剂量计等电子设备的性能。

在这项工作中，我们将介绍增加硅光电倍增管（SiPM）TRL的努力。在2019年初，我们已经将四颗6毫米SiPM集成到40千克卫星中，以研究它们在太空中的性能。每个SiPM都封装在单独的不透光铝制外壳中，其中包括用于激励的LED。SiPM和LED在直流电流模式下运行。除了测量SiPM的电流和电压外，该实验还收集了遥测参数，例如温度，时间戳和轨道位置。
