INTRODUCTION Satrack receives, rebroadcast, records & SATRACK is the acronym for SATellite missile TRACKing system. Satrack receives, rebroadcast, records & tracks the satellite signals. Provides the Post-Flight processing System. Error Evaluation methodology for the guidance of Ballistic Missile.

EVOLUTION SATRACK I : A technology project to develop and demonstrate the instrumentation and processing system using the Trident I missile (1973–1983). SATRACK II : The operational system designed to meet system requirements for the Trident II missile (1983–present). SATRACK III : Current system upgrade and future applications.

APL APL conceived and led the development of the SATRACK system. APL developed Prototype instrumentation requirement for Missile and generated specifications controlling the development Of operating missile & ground station hardware. APL satellite has operated as back up SATRACK recording site.

WHY SATRACK NEED?? Early guidance system were based on impact scoring techniques. Lack of Accuracy in flight environment. Precise error measurements and accuracy were the main contributions made by the SATRACK. Lack of progressive hardware .

HARDWARE REQUIRED Sharc processor Data Simulator Telemetry Satracker

THE SHARC The SHARC is unique in that it’s internal memory is capable of holding a large program as well a large amount of data. It is Designed for point to point Connection. SHARC has 6 link ports that can transport data at high rate.

Satracker A highly integrated, tracking device . For added security , magnetic temper & removal temper create an alarm notification. 3. Motion sensor .

SATRACK MEASUREMENT CONCEPT GPS satellites (L-band signals) First IF and GPS Signal filter S-band Power amplifier M2 L-band Low noise amplifier M1 Oscillator and Frequency synthesizer Missile translator (S-band signal) Recording equipment APL Post processing facility (Signal Data)

Determina-tion facility SATRACK CONFIGURATION Post flight Real time GPS Satellites GPS tracking Clock Determina-tion facility Test missile Tracking antenna Post flight receiver Tracker correct-ion Missile Proce-ssor Preamplifier Range Safety system Telemetry receiver Translator receiver data Telemetry processor SATRACK recorder Translator recorder

ADVANTAGES Supervisory Position Reporting External Sensor Supported Geo- Fencing Integrated Motion Sensor Field programmable

CURRENT TRENDS Batch mode processing Full Digital implementation Evolution Capability for cumulative flight test Accuracy. Flexible architecture Receiver. (FAR)

APPLICATIONS Provides error guidance model. Best flight path for Aircrafts during post flight processing. Provides error guidance model.

Uses of SATRACK for Army and Air Force missile test Orbitary Determination of Vehicle Tracking. Uses of SATRACK for Army and Air Force missile test applications (1983–present)

In Satellite Communication used as Recorder, guidance system, and Interpreter.

CONCLUSION SATRACK technology is a significant contributor to the successful Development and operational success of the trident missile. It provides a unique monitoring function that is critical to the maintenance of strategic weapon system. SATRACK will continue to support the Navy’s strategic weapon system operation.
