The company was founded in 1973 and operated from 2004 till 2019 as subsidiary of General Dynamics SATCOM Technologies, a USA based business unit of General Dynamics C4 Systems, operating as General Dynamics Mission Systems. VertexRSI was owned by Tripoint Global, a privately held company in New York who bought Vertex in 1999 from Vertex Corp. Tripoint Global was composed that time of RSI, Prodelin, Gabriel Electronics & Microwave and CSA Wireless Communications. Tripoint Global merged Vertex with RSI to become VertexRSI. GDSatcom acquired Trpoint Global in 2004.

In 2019 VertexRSI (GDSatcom) was acquired by CPI, Inc.
