WIRELESS COMMUNICATIONS IN SPACE
COMPUTER TECHNOLOGY
ORIGINATING TECHNOLOGY/ NASA CONTRIBUTION
In 1992, NASA and the U.S. Department of Defense
jointly commissioned the research and development
of a technology solution to address the challenges
and requirements of communicating with their
spacecraft. The project yielded an international
consortium composed of representatives from the
space science community, industry, and academia.
This group of experts developed a broad suite
of protocols specifically designed for space-based
communications, known today as
Space Communications
Protocol Standards (SCPS). Having been internationally
standardized by the Consultative Committee on
Space Data Systems and the International Standards
Organization, SCPS is distributed as open source
technology by NASA’s Jet Propulsion Laboratory
(JPL). The protocols are used for every national
space mission that takes place today.
PARTNERSHIP
Engineers from
Global Science & Technology, Inc. (GST), of Greenbelt, Maryland, were the principal developers
of the SCPS suite of protocols. The company’s chief
engineer was the lead architect for the SCPS transport
protocol, and GST personnel authored the SCPS Rationale
Green Book. Many of the company’s protocol engineers
played integral roles in early SCPS development,
including some of the first testing and operational
deployments of the technology. Today, GST represents
NASA at the Consultative Committee on Space Data
Systems, and leads several international space
networking consortia, including the Interplanetary
Networking Research Group.
It was a natural extension of GST’s business to
take its SCPS research and development effort and
transfer it into the commercial satellite and wireless
markets. In 2000, the company began commercializing
the transport protocol component of the SCPS suite.
The development of this transport protocol was
funded by NASA’s Goddard Space Flight Center at
the start of the original research and development
project. This funding was critical in defining
the need for the technology, crafting the specification
for the protocol, and building the reference implementation
that served as the blueprint for what eventually
would become SkipWare,® the commercial implementation
of the SCPS transport protocol.

Comtech EF Data’s turboIP™ is the primary hardware platform bearing SkipWare®
software.
|
While no formal technology transfer partnership
between GST and NASA was necessary for the company’s
commercialization efforts, GST alerted all the
relevant parties within NASA of its intentions
to productize SCPS, and kept them apprised of its
progress as the technology went to market. Recognizing
GST’s unique lineage with the technology, NASA
showed great support for the company’s intention
to commercialize SCPS, and continues to support
its efforts as the technology expands into new
products and markets.
Today, NASA funds the maintenance of the SCPS reference
implementation (an open-source blueprint of the
code on which SkipWare is loosely based) through
JPL, which serves to promote the SCPS technology
within both the Federal technology sector and the
commercial wireless market. Both JPL and Goddard
generally promote SCPS within the space community,
and wherever appropriate, will direct potential
customers interested in the SCPS technology to
GST and the SkipWare line. The company continues
to work closely with interested parties at Goddard
to keep them informed of SkipWare releases, new
product features, and new market applications of
the technology. GST also actively solicits input
from NASA regarding future requirements for space
networking and how it can best develop its technology
to meet the needs of the space community. The company
maintains an ongoing dialogue with the space networking
experts within NASA, and this affiliation promises
to help promote and advance the SkipWare product.
PRODUCT OUTCOME
Global Protocols, Inc., an independent company
spun off from GST for the purposes of commercializing
its wireless protocol line, distributes SkipWare
as a software license and as an embedded service
on the hardware platforms of its partner, Comtech
EF Data, a satellite products company based in
Tempe, Arizona. SkipWare mitigates or eliminates
the obstacles associated with wireless and satellite
transport and provides efficient, reliable transmission
over these media. Global Protocols has sold the
technology to customers operating in the satellite,
terrestrial wireless, and wireless telemetry
markets, and its customer base includes major
wireless Internet
Service Providers both domestically and internationally,
as well as every U.S. military branch.

Comtech EF Data, a satellite products company, distributes SkipWare® as an embedded
service on its hardware platforms.

Since being adopted as the military standard
for stressed wireless networking, sales of SkipWare-enabled
platforms in the military wireless market have
increased substantially. The primary hardware
platform
bearing SkipWare is turboIP,™ a rackmount accelerator
manufactured and distributed by Comtech EF Data.
Developed through a collaborative partnership
between Global Protocols and Comtech EF Data,
turboIP represents
a technology breakthrough in Internet-over-satellite
platforms, combining high performance with open
standards and network interoperability. These
platforms sell at a rate of approximately 100
units per month,
and generate significant support and engineering
services revenues after each sale.
Offering both router mode and abridged mode (EasyConnect™),
turboIP provides unprecedented ease-of-installation
while reducing maintenance (training) costs.
Network availability is enhanced with turboIP
by addressing
the single-point-of-failure issue using fail-to-wire
technology. This technology ensures network connectivity
in the event of any turboIP failure including
loss of power. Global Protocols and Comtech EF
Data
are continuing collaborative efforts and will,
later this year, offer increased high-end features
including Lempel-Ziv datagram compression and
Selective Acceleration (patent pending).
Global Protocols has increased its engineering
staff to meet the demand for its protocol engineering
and integration services, and expects to continue
to grow this business as new wireless media markets
prosper. Having defined protocol engineering
as a marketable service and having established
SCPS
as the standard in wireless data transport, several
other companies have entered the market. Due
in large part to NASA Goddard’s vision and its
forecasts
for the need of high-performance protocols in
wireless media, a new and prosperous business
line is forming within the wireless communications market.
