This document summarizes a seminar on obstacle detection using GPS systems. The seminar was presented by four students under the guidance of their professor from the Department of Computer Technology. The seminar covered the introduction of GPS and location-based services, the motivation and problem statement for the seminar topic, objectives of obstacle detection using GPS, a literature review, and the expected system architecture and conclusion. The seminar aimed to discuss updating GPS locations quickly, selecting optimal routes, changing profiles based on location, tracking locations of friends and family via SMS, and detecting restricted areas.

3. INTRODUCTIONINTRODUCTION
Global Positioning System (GPS) is a spacebased
satellite navigation system provides location & time
data in all weather conditions, anywhere on or near
the Earth
• It is maintained by the United States govt & is freely
accessible to anyone with a GPS receiver.
• Contains Computer that "triangulates" its own
position by getting bearings from at least 3 satellites.
• Resultant data is provided in the form of a
geographic position - longitude and latitude - within
an accuracy of 10 to 100 meters.

4. INTRODUCTIONINTRODUCTION
Location Based Services(LBS)
• Determine nearest possible location of places like
hotels,ATM etc
• Receive beneficial alerts such as-news about traffic
jams,sale in shopping malls,specific route.
• LBS services are typically made for customers-
-Public safety
-Consumer services
-Reminders

5. MOTIVATIONMOTIVATION
To make route easy :-
• To assist with the exact information, at right place in
real time with personalized setup and location
sensitiveness.
• To provide Location Based Services

6. PROBLEM STATEMENTPROBLEM STATEMENT
• Updation of GPS in less time.
• Selecting shortest route from ‘n’ route.
• Changing route from one to another.
• Message sending in emergency situation via text
message.

7. OBJECTIVEOBJECTIVE
• Update GPS in less time.
• Select appropriate route in runtime.
• Profile changer based on place or area.
• Person Location tracking by Family Member(SMS).
• Nearest Friends notification reminder.
• Restricted area.

10. EXPECTED CONCLUSIONEXPECTED CONCLUSION
• There are various constraints to implement Location
Based Services. The different kinds of constraints
include :
• Technology Constraints :-
• The most important factor in enabling the growth of
LBS is wide availability of cheap GPS enabled
handsets. GPS enabled handsets are being
manufactured now days.
