Multipath Control |
GPS code phase measurements are subject to errors due to multipath effects, which are due to the satellite signals taking multiple paths before reaching the receiving antenna. The GPS receiver can see a composite of the direct signal, and one or more indirect signals that are reflected off of objects near the antenna. This can result in several meters of bias in the individual code phase measurements, which will vary from moment to moment.
By default, the NetRS uses Everest® Multipath Reduction, a Trimble proprietary technique that reduces the effects of multipath on the code phase measurements. This function can be disabled or enabled as needed on your system. This control is access through the Receiver Configuration - Multipath Control page.
Under normal conditions, it is recommended that Multipath Reduction be enabled.
