CE 2.2 Project Background
CE 2.2.1 Characteristics of the project
This project can be stated as the next generation GPS receiver technology that can be
operated using a software and provide Position, Velocity, Time (PVT), meters level accuracy,
and independent raw measurements solution through evaluating 1-2 millisecond of the IQ
samples. I have developed the system in manner to ensure the elimination of the problems related
to the lock in the tracking loops through eliminating the tracking loops in the overall system. I
have implemented the system that enables the initial time tagging through an external source of
time along with the errors of 10th part of a minute. I have implemented the evaluation of the IQ
samples in very fast rate of 500 Hz in streaming mode. This system consumes minimum power
and provides the position accuracy of the tracked object.

CE 2.2.2 Objectives developed for the project
Tracking the subject through GPS is a very costly system and is less reliable because of
the less accuracy in locating the subject (it might be very less). There are many problems related
to these problems however, I had set certain objectives to eliminate these problems and make the
system much reliable and efficient. Following are the objectives set for the success of the project:
 To develop a system that is much accurate
 To eliminate the problems those were highlighted in the previous system
 To keep the budget of the project very low as much possible
 To play my roles with responsibilities as a leader
 To eliminate the loop tracking
 To present the output at the faster rate

embedded the algorithm within the microprocessor in manner to host the system and track the
subject. I had used RFIC solely for the extraction of the demodulated and down-convert GPS
signals and the output in the format of the digital I/Q. I had implemented the conventional
software based operating system whose receivers decode, track, and acquire the GPS navigation
message through evaluate the I/Q samples in the real-time.

The software embedded within the system enables the receiver to acquire, track, and
decode the messages in the real-time gathered through the GPS navigation in manner to identify
all the satellites can promote the transmission of the signal. For the position, Velocity, and Time
computation the receiver tracked the signal and record the navigation message bit data
eliminating the carrier wave for the decoding of the signal. I have embedded the coding in
manner that the almanac data or the ephemeris data are available to the satellite that implies to
the decoding of the information related to the Ionospheric correction parameters for the satellite
clock corrections parameters and the single-frequency users at the same time or later. I have

respectively to minimize the power consumption that should be activated long enough in manner
to process the 2 ms I/Q samples. The system comprised of four utilities that can be listed as
StoreGPS, Verify GPS, GetOrbitInfo, and ProcessGPS for the complete exchange of the
information through signals.

Conventional software based GPS receiver technologies are not capable of fulfilling the
