• ADVANTAGES OF GENERAL PURPOSE TELEMETRY DATA AND CONTROL SYSTEMS

      A key milestone for every telemetry design is that date when everyone agrees on a definition of the design requirements. Unfortunately, specifications often become obscured as test constraints change, additional requirements are uncovered, test objectives are more clearly defined, and budgets are cut in half. Historically, telemetry designs using technology, hardware, and philosophy that pre-date Christopher Columbus have caused obvious rigidity to the system design and its operation. Once completed, program managers become ruefully aware that these systems are difficult (if not impossible) to modify and are always very costly to change. Telemetry systems available today offer the flexibility necessary to accommodate a frequently changing measurement list. Not only can the measurement list be changed, it can be changed during the course of a test in progress. If requirements expand, hardware may be added. If the test is a non-destructive test, the system can be configured for use on future programs.
