1. A method of operation of a navigation system comprising:
- sampling a first location reading for locating a device;
sampling a second location reading for locating the device;
calculating an estimated location based on a velocity of the first location reading;
validating the second location reading based on comparing the second location reading to the estimated location;
storing invalid samples based on the second location reading found invalid; and
operating a predetermined response based on the invalid samples exceeding a predefined threshold for displaying on the device.

Abstract
A method of operation of a navigation system includes sampling a first location reading from a device; sampling a first time stamp associated with the first location reading; sampling a second location reading from the device; sampling a second time stamp associated with the second location reading; obtaining a velocity for the device between the first location reading and the second location reading; and validating the second location reading with the first location reading, the first time stamp, the second time stamp, and the velocity for displaying on the device.
