Vanguard Space Technologies has built Bus Structures for a number of critical commercial, defense and space research missions including BSAT-2c, SBIRS GEO-3 and GEO-4, ANGELS, IRIS, OCO-1 and OCO-2, LADEE and AEHF SV5 and SV6. These structures have ranged in size from 36 to 192 inches tall. The designs include modular, center cylinder, panel and A2100 variants. With the 2009 addition of our Eastgate facility, we now have complete assembly, integration and test capabilities for spacecraft assembly and integration, OSR bonding, heat pipe panel fabrication and final thermal coatings. Structural verification via thermal cycling, static load testing and panel-level NDE are an integral part of our comprehensive Bus Structure product offering.
