International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / Ongoing work at National Aeronautics and Space Administration Goddard Space Flight Center
(NASA/GSFC), seeks to apply standard Internet applications and protocols to meet the technology
challenge of future satellite missions. Internet protocols and technologies are under study as a future
means to provide seamless dynamic communication among heterogeneous instruments, spacecraft,
ground stations, constellations of spacecraft, and science investigators.
The primary objective is to design and demonstrate in the laboratory the automated end-to-end
transport of files in a simulated dynamic space environment using off-the-shelf, low-cost,
commodity-level standard applications and protocols. The demonstrated functions and capabilities
will become increasingly significant in the years to come as both earth and space science missions
fly more sensors and the present labor-intensive, mission-specific techniques for processing and
routing data become prohibitively.
This paper describes how an IP-based communication architecture can support all existing
operations concepts and how it will enable some new and complex communication and science
concepts. The authors identify specific end-to-end data flows from the instruments to the control
centers and scientists, and then describe how each data flow can be supported using standard Internet
protocols and applications. The scenarios include normal data downlink and command uplink as
well as recovery scenarios for both onboard and ground failures. The scenarios are based on an Earth
orbiting spacecraft with downlink data rates from 300 Kbps to 4 Mbps. Included examples are based
on designs currently being investigated for potential use by the Global Precipitation Measurement
(GPM) mission.
