3. 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.

4. 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.

5. 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.

6. 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 .

7. HARDWARE REQUIRED
Sharc processor
Data Simulator
Telemetry
Satracker

8. 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.

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