LC86G same place with different coordinates

Hello, I have a GPS module LC86G, and I test it in one place for a long time
the coordinates all time are different I took about 800 RCM readings.
why coordinates are different in same place?

Hi @HamdyNassar2024
The positioning accuracy of the LC86G module in the open environment is 1.5 m. In different environments, the positioning accuracy will have some deviations.
What is the environment you tested in? Is there any obstruction? Please provide specific information. Can you also provide the positioning information you received?

Hi George,
Thanks for your replaying, I tested LC86G in my company, I put the GPS external antenna out of window.
