COSMOS Purpose Comprehensive Open-architecture Space Mission Operations System (COSMOS)*

• Purpose: To develop a comprehensive open system of software and

hardware tools that supports the design, testing, and operations of one or more spacecraft and is easily adaptable for adding spacecraft and porting to Mission Operations Centers (MOCs) at HSFL, NASA Ames Research Center, and other MOCs. – COSMOS was developed as a collaboration between HSFL and NASA

Ames Research Center under a 3-year NASA EPSCoR grant (2010-2013).

Mission Operations Support Tool (MOST) • Primary visualization and commanding tool of COSMOS designed

specifically for supporting near-realtime operations. • MOST functions:

– Spacecraft/payload monitor and control – Mission Planning – Simulations and testing – Training and rehearsals – Trending and analysis – Anomaly resolution

• Designed initially to support HSFL’s HawaiiSat-1 mission • Adapted to support missions with multiple elements


MOST Background • Based on legacy programs designed by Dr. Sorensen for the

Naval Research Laboratory: – UltraViolet Plume Instrument (UVPI) Encounter Manager for

SDIO/LACE satellite encounter with sounding rockets (1991) – LUNOPS program used to monitor science mission operations

during the Clementine lunar mission (1994)

COSMOS and Hawai`iSat-1

• COSMOS has three primary nodes for Hawai`iSat-1 mission – HiakaSat – HSFL Mission Operations Center(HMOC)

• 1 agent • Uses COSMOS Core, MOST, MPST, DMT, GSCT, and TBCT

– KCC ground station • 8 devices (ground station computer, 2 Azimuth/ Elevation

antenna controllers, 3 radio control interfaces, and 2 terminal node controllers)

• mapping to about 150 entries in the Namespace. • Control of the ground station is implemented through 8

agents

26


HiakaSat Use of COSMOS

• COSMOS is the Flight Software on the satellite – Uses internal COSMOS nodal architecture, with 78

devices, mapping to 3715 entry points in the COSMOS namespace

– Control of HiakaSat implemented through six agents. • 3 agents make up the basic autonomous node:

– handles execution of tasks at specific times or events – state of health data collection – high-level inter-node file transfer

• 3 agents are device specific to handle low-level satellite functionalities, as well as setup of inter-node data transfer channels over radio links

27


Conclusion

• COSMOS is an innovative new software system that provides a new paradigm for mission operations being used for the first time in space on the Hawai`iSat-1 mission

• Hawai`iSat-1 and its HiakaSat satellite, to be launched on the first launch of the Super Strypi on the ORS-4 mission in 2015, will test an innovative miniature thermal hyperspectral imager that could be used in future Earth Observation missions
