hey
iam running an arduino mega system with a Gsm Shield.
iam trying to get the position of my system by reading the cell informations. the position of each cellid iam getting by opencellId.com.
my code so far:
Answer:
its working pretty fine but my deviation of my position is almost 2km. Yea i know about the accuracy of gsm positioning. But i ve read that the accuracy can be adjusted by using the Time Advance Data from gsm. unfortunately iam getting the Time Advance Data only for the maincell.
Do you have any experience in positioning only by gsm/cell data? can you confirm that you receive only TA Data for your maincell?

my code so far:
Code:
Serial1.write("AT+CENG=3,1\r"); // Set output details of gsm
Serial1.write("AT+CENG?\r"); // request cell infosIam using the rxl value to caculate a connected adjustment.
