MX systems study

This report summarizes the results of two investigations performed in support of the MX Full Scale Engineering Development program. The first investigation focused on alternative ways to present guidance system test data to enhance the effectiveness of preflight accuracy assurance procedures. The attributes of a desirable accuracy assurance system are discussed and the nature of the required structure and contents of such a system in the MX guidance context are defined. A review of the MX guidance production test structure is presented from which potential traceability parameters are then identified. The second investigation addressed the potential value of the SATRACK range instrumentation system to MX testing on the Western Test Range. Mathematical models describing the errors associated with the MX guidance system, the SATRACK system, and the environmental factors that affect system performance were developed. Particular attention was paid to the gravitational and ionospheric delay errors.
