About GLSV

Who we are

GLSV are the sound and vibration experts with years of field experience and a team of outstanding engineers. We are vertically integrated, with all of our engineering, design, and manufacturing done in-house. We lead with a strong focus of manufacturing for the DoD from single parts to ground-up, full product development and production. We have an advanced skill set in metal fabrication and manufacturing, and our 47,000 square foot facility provides the capacity to produce prototype quantities through high volume production quantities.

GLSV operates 100% in house from idea to manufacturing and provide high quality customer specific solutions. The majority of our diverse team of engineers have traveled across the U.S. and landed at Michigan Technological University. We became home to those who couldn’t imagine leaving.
