35. he GPS constellation has been designed so as to provide a minimum of 4 visible satellites at any location at all times The number of visible satellites can decrease due to blockage by objects such as trees and buildings Multipath It is possible for satellite signals to reflect off large nearby objects such as buildings cars or even the ground thereby resulting in an erroneous distance measurement This phenomenon is known as multipath Multipath can cause significant errors in the position determination and it is therefore important to place the receiver in an environment which is free of large reflective surfaces It is also recommended to mount the receiver directly onto a surface while maintaining a clear view of the sky in all directions OmniSTAR 12 Global Positioning System Issue 1 0 05 03 OmniSTAR 8300HP User Manual seo Waa v Figure 4 Multipath Position Dilution of Precision PDOP The Position Dilution of Precision PDOP is a measure of the satellite geometry The lower the PDOP value the more accurate the GPS position will be Satellite elevations The signal from a satellite that is low on the horizon will travel a greater distance through the atmosphere This results in a lower signal strength and a delayed reception thereby causing erroneous and noisy data By default the 8300HP is configured to ignore any satellites that have an elevation angle lower than 5 f
