WebMultipath is the corruption of the direct GPS signal by one or more signals reflected from the local surroundings. Multipath reflections affect both the carrier phase measured by the receiver and signal-to-noise ratio (SNR). A technique is described which uses the SNR information to correct multipath errors in differential phase observations. Web1 apr. 2008 · The phase multipath error is expressed as δϕ, in units of cycles. The reflected signal's carrier wave, upon reception by the GPS antenna, will likely have a different …
