2. contents Introduction. Why Satrack need. How Satrack works. Hardware required. Implementation. Advantages. Applications. Future Directions. Conclusion.

3. Introduction Satrack receives, rebroadcast, records & tracks the satellite signals. Guidance system. Data use as Error model. Integrated with Every Weapon System. Provides the Post-Flight processing System.

4. Why Satrack need? Early weapon systems depended on the impact of scoring techniques. Accuracy was less. Lack of accuracy in flight test Environment. Broad ocean test ranges. Lack of Progressive Hardware & Software.

5. How Satrack Works?

6. Hardware required… Sharc Processor. Data Simulators. Telemetry. Satracker.

7. TELEMETRY Telemetry  is an automated communications process by which measurements and other data are collected at remote or inaccessible points and transmitted to receiving equipment for monitoring. The word is derived from Greek roots: tele = remote, and metron = measure.

8. Satracker Data is accessible via the internet through C3 Location Systems. Configurable using a laptop or PDA.

9. SHARC PROCESSOR THE SHARC is unique in that its 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.

10. 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 tomeet system requirements for the Trident II missile(1983–present). SATRACK III : Current system upgrade and future applications.

11. Future Directions… Batch mode Processing Full Digital Implementation. Evaluation Capability for cumulative flight test Accuracy. Flexible architecture Receiver.

12. EVALUATION CAPABILITY FOR CUMULATIVE FLIGHT TEST ACCURACY The limitations of the test geometry prohibit observations of all the errors in any single flight test. Since each test flight provides observations of the underlying system missile guidance error models, the data can be combined from may flight tests. The final cumulative analysis of flight test data produces a guidance error model of the weapons system.

13. FULL DIGITAL IMPLEMENTATION . The full digital implementation is of the Portable ground equipment and processing facility. So, the results are expected to be repeatable. This is a very big improvement over the Analog circuitry such as the Analog PLLs used for carrier- phase tracking loop. In addition, the digital implementation removes the need for periodic hardware calibration that accompanies the analogckt .

14. BATCH MODE PROCESSING This type of processing allows hardware to operate with software like flexibility. As the pure software system was too slow, hardware that is fully configurable under software control implemented the most computing intensive portions of the process such as signal correlation, generation of local code and carrier signal mixing. It is possible to acquire the signal with virtually no acquisition delay by conducting extensive searches with initial batch of data until all the signal is found.

15. FLEXIBLE ARCHITECTURE RECEIVER The batch mode processing has been applied to stand alone real time capable receiver called FAR. It retains the essence of batch mode architecture. While maintaining the capability to process the data in real time. FAR is a single channel L1 C/A only receiver with a front-end data storage memory that buffers unto one s of data. It can track up to 16 satellites in real time without any loss from channel multiplexing

16. Advantages Supervisory Position Reporting .- Device wakes up, locates by GPS, transmits location, resumes sleep mode. Up to 12 programmable sleep intervals or wake up settings. External Sensors Supported .-Sensors can be Dry contact, Custom Serial, Universal Multimode Sensors (humidity, light, refrigerated temperature, door, dry contact). Integrated Motion Sensor .-Message on start and stop, engage interval override on motion for time or motion duration. Geo-Fencing .- Device alarms when it is outside the geographical boundaries set for it. Field Programmable .-Configurable using a laptop or PDA.

17. Applications The best flight path for Aircrafts during post flight processing. Provides error guidance model. 1) FLY – BY – WIRE SYSTEM (DRONES)

18. 2. Orbitary Determination of Vehical Tracking.

19. 3. In the Satellite Communication used as recorder ,guidance system, and Interpreter.

20. Conclusion SATRACK is a significant contributor to the successful development of and operational success of the trident weapons system. It provides a unique monitoring function that is critical to the maintenance of strategic weapons systems. The development of SATRACK looks forward to the implementation of the Low Cost Missile Test Kit. one other main development from this technology was the development of sophisticated tools for optimal target patterning. Instrumentation, analytic methods, and modelling and the use of limited and expensive flight tests assets were also born out of the SATRACK research
