Abstract

The accelerometers and the angular velocity sensor, which are part of the meteorological complex of the ExoMars-2022 landing platform (LP), are designed to measure the acceleration during the deceleration of the lander in the Martian atmosphere. Based on the data, the main parameters of the Martian atmosphere are calculated: density, pressure, and temperature. After landing, the sensors are used to determine the acceleration on the surface and vibration effects on the lander of various nature. The sensors are activated prior to entry into the atmosphere and operate during the entire descent until landing. After landing, a long-term monitoring is carried out to identify vibration effects from the atmosphere and the surface. In the paper we consider the scientific problems solved by the sensors, describe the measurement program and consider in detail the design of the sensors and their characteristics.

用于研究火星上层大气的气象综合体加速度计

加速计和角速度传感器是ExoMars-2022着陆平台(LP)气象综合体的一部分，用于测量着陆器在火星大气中减速时的加速度。根据这些数据，计算出火星大气的主要参数:密度、压力和温度。着陆器着陆后，传感器用于确定着陆器表面的加速度和各种性质的振动效应。传感器在进入大气层之前被激活，并在整个下降过程中工作直到着陆。着陆后，进行长期监测，以确定来自大气和地面的振动影响。本文考虑了传感器所要解决的科学问题，阐述了传感器的测量方案，并对传感器的设计及其特点进行了详细的论述。

期刊介绍： Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
