While GPS pseudorange is measured by the satellite and GPS local clock difference (together with some compensations for atmospheric effects), how does a GPS receiver measure the pseudorange rate? Thanks.
GPS Pseudo-range Rate Determination is a method used to determine the velocity of an object by measuring the change in distance between the object and multiple GPS satellites over time.
GPS Pseudo-range Rate Determination works by measuring the time it takes for signals to travel from GPS satellites to a receiver on the object. By comparing the time differences between multiple satellites, the change in distance over time can be calculated, which can then be used to determine the object's velocity.
The advantages of using GPS Pseudo-range Rate Determination include its ability to provide accurate velocity measurements in real-time, even in environments where other methods may be unreliable. It is also a cost-effective and efficient way to determine velocity compared to other methods.
GPS Pseudo-range Rate Determination can be used in a variety of applications, including navigation, tracking vehicles or ships, monitoring the movement of glaciers or tectonic plates, and measuring the speed of moving objects such as planes, trains, or cars.
Yes, there are some limitations to GPS Pseudo-range Rate Determination. It requires a clear line of sight between the object and GPS satellites, which can be obstructed by buildings, mountains, or other objects. It also relies on accurate timekeeping and the assumption that the object is moving in a straight line.
