Janus-1

JANUS-1 DEMO SATELLITE

JANUS-1 is a software-defined 6U small satellite created entirely on the Antaris software platform. It was designed and built with mission participants from seven countries together with our partners in India. Antaris Inc partnered with XDLINX Labs for satellite hardware bus and Ananth Technologies for AIT and launch integration, AWS and ATLAS Space Operations providing ground station services.

Key Features:

• Modular Bus, hardware abstraction that removes vendor lock-in or hardware dependency
• Modular Payloads – capable of hosting multiple payloads with security and isolation
• Onboard Edge computing capability for AI/ML, on-board decision making
• Software Defined Radio – supporting S and X band for TT&S and data downlinking
• Full functional TT&C software for satellite and payload operation
• Onboard scheduler, and algorithms for orbit determination and control

Key Specification:

• 6U Small Satellite
• Distributed compute for bus, payload edge and SDR
• 5 payloads: IoT communications, laser communications, machine learning GPU, coarse imager, FPGA
• 3- Axis ADCS for pointing and stability
