What Affects the Accuracy of my GNSS Receiver?
The accuracy of GNSS readings is affected by factors such as landscape, weather conditions, satellite position, and receiver quality.
The landscape around the receiver is one of the biggest factors in taking accurate measurements. Mountains, buildings, tree cover, and other objects can block or reflect GNSS signals. As a result, your receiver will probably work best in clear areas with little to no obstacles.
Weather and the condition of the atmosphere can also affect your accuracy. Clouds, dust, and precipitation all make it harder for satellite signals to get through to your receiver. This increases the amount of time the signal takes to reach you. As a result, the receiver may position you farther away from the satellite than you actually are if this mistake is not corrected. Thankfully, Maple Precision uses a method called RTK to compensate and set your readings back on track.
The positions of the satellites relative to the receiver and each other can also increase or decrease your accuracy. Depending on how many satellites are in range, your receiver could have many signals to work with, or just a few. Many signals is more accurate, while fewer leaves more possibility for error. One solution to this problem is to have more satellites available from the start, giving you many more signals to use. This is the advantage of GNSS versus GPS.
