About

NEXTAR is a satellite bus system developed by NEC, leveraging their extensive experience in aerospace development and advanced technologies like AI. It is designed to facilitate the rapid and cost-effective delivery of highly reliable small satellite systems. The bus is capable of supporting missions that require advanced imaging capabilities, such as radar satellites that can operate effectively in cloudy weather and at night, capturing clear surface images. The system also allows for flexible attitude changes to customize observations according to user needs. NEC provides comprehensive support for satellites utilizing the NEXTAR bus, covering development, production, launch, operation of data centers for image processing and analysis, and training for all processes. The page specifically highlights its use in the ASNARO-1 (optical sensor) and ASNARO-2 (X-Band Synthetic Aperture Radar) missions.
