Problem Statement
 The Primary purpose of the Short to Medium Range
Positional Device is to locate an automobile from a short
distance with a visual display.
 The team will be implementing Radio Frequency (RF), RF
sensors, microcontrollers, and Remote Keyless Entry
System (RKE) to locate the automobile.
Background
 Ever come out of a store and
were not able to find the car?
The Short to Medium Range
Positional Device (Car
Locator) will save time and
the embarrassment of losing
the car.
 The Car Locator will assist
the owner in finding the car
quickly and with ease.
