Question

Pergunta 9 1 pts Why is time such a significant source of error in GPS position calculations? O GPS devices determine position based on a distance calculation between GPS receiver to satellites and control segments to satellites where distances to satellite speed of light x time of difference O GPS devices determine position based on how clearly a signal comes through between receivers and satellites. It takes less time when there is more interference from tree cover, buildings, etc. O As long as there is a least three satellites to triangulate your position, the calculated distances can be off and position calculations from signal transfer time are not a source of error O Time is not a significant source of error in GPS position calculations; signals always transfer instantaneously

Explanation / Answer

the answer is a=gps devices determine positions based on distance calculation between GPS receiver to satellites and controll segments to satellites where distances to satellite=speed * time

Time is very important factor in error sources. that is why AVSTAR satellites mainly use the atomic clocks which are very accurate
