Milestones
The Global Observer® system is designed to provide capabilities not currently available, capabilities that can help save lives and property. The technologies behind Global Observer have been developed over decades of innovation at AV, tracing back to the first human powered airplane and through a series of revolutionary extreme altitude, solar-powered UAS. Today Global Observer is poised to open the stratosphere for practical use in the same way that airplanes and satellites opened the skies and space during last century.
