How many GPS satellites are required to triangulate a plan-form position?
You would need at least three GPS satellites to pinpoint your location. However, you would need a fourth to also identify your elevation.
Do hydro lines affect the GPS signal?
probably not, as the Global Positioning System uses data from several satellites to calculate the receivers position. At any given time, there are usually at least 4 GPS satellites above the horizon from anywhere on Earth. Only interference on the GPS frequency can impair the accuracy.
Can a single satellite be used to calculate latitude and longitude?
You need at least 3 satellites. More is always better.
What Is GPS Tracker?
Smartphones use GPS receivers to receive signals from GPS satellites and determine their location. GPS receivers in smartphones work by triangulating the signals from at least four GPS satellites to calculate the phone's latitude, longitude, and altitude.
How does a GPS satellite work with a GPS device?
signals from at least 3 satellites send signals to and receive signals from the gps which are then triangulated to give the exact position of the GPS unit. Most GPS units are receive only. That is they must receive positional and timing information from the GPS satellite constellation. The internal processor them computes your position based upon this data(triangulation). Generally receiving data from three or more satellite's is needed to be produce a good fix (your position) but this is also dependent upon the geometry of the satellites. The best fixes are obtained when you have signals from three or more satellites which are geometrically separated by 45 degrees.
Has at least 18 satellites?
Saturn
Can gps receivers calculate altitude?
Depends on the GPS device. Although ALL of them do have the raw data received from the satellites in order to calculate it, you would have to to consult your specific device to know if it will to provide the user with that information. Simply put, a GPS is time data receiver. It receives time data from many satellites and according to the time it took from the data to get to the device ( always some milliseconds), it calculates the distance from each one of them. Once it has determined the distance from at least a number of satellites (usually at least 4), a mathematical function will determine the exact 3-dimensional position of the GPS itself; that is Latitude, longitude and altitude. All you will have to do is determine whether a specific GPS brand and model will display the altitude numbers also or only latitude and longitude.
What is the difference between three satellite system and four satellite system in GPS?
Accuracy, you need at least three satellites too determine a position on earth. However, as far as GPS is concerned, more is better; therefore four would give you a more accurate position than three would. There are currently 24 satellites available for GPS systems to use.
What planet has most satellites?
Saturn, it has at least 18 moons.
How many planets do not have any satellites?
Of the eight planets in our solar system, only Mercury and Venus have no known satellites. Furthermore, Pluto has at least four of them.
How many satellites do you need to have a full GPS signal?
At leAst 3
Which planet has the most planetary satellites?
If by planetary satellites you mean Moons, that would be Jupiter with at least 63 confirmed moons - possibly more!
