Jeffries Technologies Solutions, Inc. (JeTSI) is an aerospace engineering consulting firm. We bring together experts with a diverse skill set developed throughout their careers within the aerospace industry. Whether working with NASA, NOAA, the Department of Defense, a large prime contractor, or in the private aerospace industry, our consultants have been integral participants in some of the top space efforts of the last twenty years.
Just some of the projects our engineering consultants have been part of include Space Communications and Navigation (SCaN), Space Network Ground Sustainment System (SGSS), Solar Dynamics Observatory (SDO), Cassini-Huygens Mission to Saturn, United States Air Force Satellite Operations, Department of Defense Intelligence, NASA’s Science Mission Support Office, and Mars, Discovery, and Explorer Missions.
JeTSI is an Associate Member with the Consultative Committee for Space Data Systems (CCSDS).
JeTSI was established in 2003 by husband and wife team, Alan and Leslie Jeffries. They decided to take their systems engineering and software development expertise directly to the industry through their own company. In 2013 we celebrated ten years of success working on interesting and challenging space projects, and working with some of the brightest minds in the aerospace industry.
A woman-owned business, JeTSI is headquartered in Norfolk, Virginia. From inception until early 2009, the company was comprised of the two owners and a series of engineering services contracts with various NASA efforts, all associated with either the Goddard Flight Space Center or the Langley Research Center’s SOMA. In 2009 our company began to expand its work, growing initially by bringing on consultants to provide short term specialized support to projects. By the end of the year, JeTSI transitioned these consultants to employees and began hiring engineers.
A pioneer in the area of corporate teleworking, JeTSI engineering consultants work from their home and at client work sites when necessary. We have no brick-&-mortar costs, and instead invest in our corporate computer and communications infrastructure allowing our employees to work efficiently from any location.
This accomplishes two significant goals of JeTSI:
Providing a balance of lifestyle choices for our career-tested aerospace engineers – empowering them to work on challenging projects and share their ideas and expertise while living the type of lifestyle they choose; and
Reducing the carbon foot-print by reducing the number of cars on the road daily and the additional building costs of housing a company. Since our engineers work primarily from home, gas usage and emissions are reduced. With no separate company headquarters building, we save on heating, water, and paper products.
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.

Wettest Year on Record for Many Cities in the Eastern U.S.
For much of 2018, satellite images have shown the Eastern U.S. covered in a thick blanket of clouds – and for good reason: Time and again, major storms have soaked the Mid-Atlantic and parts of the South with abundant rainfall. As the year draws to a close, the National Weather Service reports more than a dozen major cities have now had their wettest calendar year on record, including Washington, D.C., Baltimore, Md., and Wilmington, N.C.
On the morning of December 15, NOAA’s GOES East satellite captured this image of the recent weekend storm that drenched the Mid-Atlantic. Nearly 3.5 inches of rain fell in Washington, D.C., more than enough to set a new milestone for the city’s wettest year on record. By the time the deluge had ended, Washington’s 2018 precipitation total had climbed to 64.22 inches, blowing the previous calendar year record (61.33 inches, set in 1889) out of the water. In a typical year, the nation’s capital receives about 40 inches of precipitation.
In Wilmington, North Carolina, this year’s rainfall has surpassed 100 inches, an amount more than 3 feet above normal. The flooding rains that fell during Hurricane Florence in September helped contribute to Wilmington’s triple-digit total.
Many locations that have set precipitation records will likely add to their totals before 2018 ends. NOAA’s Climate Prediction Center is forecasting above-normal precipitation in the Central and Eastern U.S. through the end of the year. With an El Niño still likely to form in the tropical Pacific Ocean, a wetter-than-normal winter may be in store for the Mid-Atlantic and Southeast U.S.
