Finding the distance travelled using a GPS module

[Shafie]

Hello, can anyone help me by providing the C codings for calculating the distance travelled by a vehicle (example – bus) which has a GPS module interfaced to a AT89C51 micro controller ?

Hi,

 

We can find distance as from GPS we can only get the location..

 I think we can just notedown the location from gprs from beginning ofthe journey to the end

 

now we need to do some cordinate geomentry..

 

caliculate the lengths between consegutive locations and  find the sum of all lengths.. this will be the distance travelled………

Hi,

 

With this idea, you can only find approximate distance and you have to take samples at very high speed…

 

What is the issue, let me explain…

 

Near the center of erth if u will find difference of langitude say x it will correspond to distance X..

 

but at north or south pole longitude difference of x corresponds to distance Y …

 

but X will not be equal to Y even though longitude difference is same as x…

 

If you want to find difference in ur city or state, than its fine …
