The aircraft currently being used to support the Navy’s mission of Telemetry Reception, Range Safety as well as Range Surveillance/Clearance are reaching the end of their useful life. As a result, there are ongoing efforts to procure a new aircraft and integrate these mission systems in order to continue the support of critical Naval Test Range operations. This paper will detail the current efforts being undertaken to upgrade a Gulfstream 550 to perform Range Support missions for the Multi-service Government Test Ranges.
