Jeffries Technologies Solutions, Inc. (JeTSI) is a relatively young and small, woman-owned company headquartered in Herndon, Virgnia. Leslie and Alan Jeffries, the principle owners, established JeTSI in 2003.

JeTSI’s corporate model is that of the tele-working or telecommuting engineering services provider. We have no brick-&-mortar costs at this time, and instead invest in our corporate computer and communications infrastructure, which allows our employees to work efficiently from any location. We believe this approach sets JeTSI apart since it reduces enormous energy costs for facilities and commuting, while providing experienced and premier engineering resources to our customers.

• Provide technical support to numerous Systems Engineering and Technology laboratory studies (CCSDS recommendation and overall communications architecture related)
• Project liaison to CCSDS
• Provide lead technical support to SGSS technology laboratory (Building 13)

• Provide requirements development, analysis and traceability support (via Cradle) to the Space Communications and Navigation (SCaN) level 2 engineering effort
  • SCaN encompasses the SN, NEN and DSN
  • https://www.spacecomm.nasa.gov/spacecomm/default.cfm
• SCaN and its Level 2 engineering effort have evolved since the prior ECANS and SCIP phases, and continues to be a very dynamic environment
• JeTSI is one of the few contractors to have been retained throughout this evolutionary process due to its unique and critical expertise across the SCaN networks and ground systems in general

• Technical Consultant for upgrading SOHO operations system to utilize Space Link Extension (SLE) protocols to access DSN and ESA deep space antennas.
• Coordination and oversight for SLE software development effort
• Liaison with ESA on developing joint interface agreement with SSMO, DSN and ESA for SLE services
• SSMO expanded effort to migrate SLE into ACE Mission Operations System

• Supported development of Architecture, Concept of Operations and Requirements for the Exploration Program’s Communication and Navigation infrastructure, utilizing the Space Network (SN), Near Earth Network (NEN), Deep Space Network (DSN) and a proposed Lunar Communications Network.

• Provided communications architecture and engineering support in defining the communications and navigation approach for Constellation’s ISS and Lunar Phases
• Chaired the SCaN-CxP IP Tiger Team panel consisting of representatives from the SN, DSN, NEN, NISN, Cx SAVIO, Cx MS, Cx GS, Cx Orion and Cx Ares organizations.
  • The panel resolved the overall architecture of applying an IP-based network to all phases of the CxP flight regime, including defining interface boundaries and responsibilities between SCaN (SN, DSN, NEN and NISN) and CxP (MS, GS, Orion, Ares, Altair, Lunar Surface Systems).
  • Produced requirements, architectures, data flow diagrams and many other engineering products.
• Supported SCaN-CxP Interface Working Groups in developing IRDs between SCaN and CxP Mission Systems, Ground System, Ares and Orion
