Abstract
The apparatus is an earth horizon crossing indicator used in a spacecraft attitude control system, which uses power from a self-contained battery rather than power from the spacecraft electrical system. The battery is typically of the lithium thionyl chloride type. This reduces the weight and complexity of the spacecraft attitude control system and allows the resources of the spacecraft electrical system to be used for other devices.
