Abstract
Provided is a global navigation satellite system (GNSS) navigation solution generating apparatus and method, the apparatus including a determiner to determine that a spoofing signal exists in a received GNSS signal when a signal having a receiving intensity greater than a predetermined receiving intensity of a normal signal by a predetermined value range is included in the received GNSS signal, a detector to re-detect the normal signal from the GNSS signal when the spoofing signal is determined to exist, and a calculator to generate a GNSS navigation solution by tracking the re-detected normal signal, wherein the predetermined value range is 3 to 5 decibels (dB).
