Abstract
Various modular configurated design approaches for development of devices and components of strapdown inertial units (SIU) – assemblies of sensitive elements (ASE), modules of service electronics, module of information exchange and control (MIEC) – are described in this paper. Basic ASE are under development, each of which contains three fiber-optical gyroscopes (FOG) and three pendulous accelerometers. Each ASE variant is based on FOG with specific accuracy levels (0.3; 0.05 or 0.01 °/hr). Two basic SIU types with different device structure are considered: three-channel and six-channel units based on one or two ASE, respectively. Design features of such monoblock and two-block units are studied; their main technical characteristics are estimated.
Highlights
Рассматриваются различные варианты построения бесплатформенных инерциальных блоков на основе блочно-модульного подхода к конструированию приборов и их составных частей – блоков чувствительных элементов, модулей сервисной электроники, модулей обмена и управления
Базовые трехканальные блоки чувствительных элементов (БЧЭ) устанавливаются сверху и снизу на корпус блока БЧЭ, там же можно установить модули ЭВСИ для каждого базового БЧЭ

Summary
Двухблочный вариант прибора показан на рисунке 4. Блок БЧЭ в этом случае имеет цилиндрическую форму. Базовые трехканальные БЧЭ устанавливаются сверху и снизу на корпус блока БЧЭ, там же можно установить модули ЭВСИ для каждого базового БЧЭ. В этом случае оптическая схема полностью реализуется в блоке БЧЭ
