Acquiring GPS Signal The NVE-M300 acquires positioning information transmitted from 1 to 3 tracked satellites while searching for more satellites (minimum 4 of needed). Fixing GPS Position The NVE-M300 requires continuous signals from 4 or more tracked satellites (for 30 seconds) in order to accurately fix your position. Temporary Poor GPS Coverage Thunderstorms, dense foliage or surrounding tall buildings may cause temporary loss of position fix (acceptable if under 30 seconds). Poor GPS Signal, Lost Position Fix You may have entered an area where consistently poor GPS signal (lasting 30 seconds or more) makes it impossible to maintain a position fix. No Line of Sight, Lost GPS Tracking You are in an area where line of sight to GPS satellites has been blocked.
