A dominant error source on satellite measurements is caused by a phenomenon known as multipath. In the mid-1990s, Trimble® introduced the patented Everest™ multipath rejection technology based on advanced digital signal processing. Within the satellite signal tracking loops, the reflected multipath signals were processed and ultimately rejected. This allowed sub-meter DGPS positioning and faster more reliable RTK initializations.

With the introduction of Trimble Maxwell™ 7 technology, Trimble has significantly improved the multipath mitigation performance with a patent pending technique known as Everest Plus. This technical bulletin provides an overview of how Trimble receivers provide this improvement.
