Signal strength bars Receiver status field Sky view GPS Page Power source indicator The progress of satellite acquisition is shown in three stages: • No signal strength bars-the receiver is looking for the satellites indicated. • White signal strength bars-the receiver has found the satellite and is collecting data. • Green signal strength bars-the receiver has collected the necessary data from this satellite. As soon as the GPSMAP 296 has collected the necessary data from the best satellites in view to calculate a fix, the status field indicates the status of the receiver. The unit then updates the location, date and time. GETTING STARTED > GETTING SATELLITE SIGNALS Receiver Status The Receiver Status field shows one of the following conditions: • Searching the Sky-the receiver is looking for satellites. • AutoLocate-the receiver is looking for any satellite whose almanac has been collected, which can take up to 5 minutes. • Acquiring Satellites-the receiver is looking for and collecting data from satellites visible at its last known or initialized location, but has not acquired a fix. • 2D GPS Location-At least three satellites have been acquired and a two-dimensional location fix has been calculated. "2D Differential" appears when you are receiving DGPS corrections in 2D mode and a "D" appears on the strength bar of satellites being corrected. • 3D GPS Location-At least four satellites have been acquired and a three-dimensional fix has been calculated. "3D Differential" appears when you are receiving DGPS corrections in 3D mode and a "D" appears on the strength bar of satellites being corrected. • Lost Satellite Reception-the receiver is no longer tracking enough satellites for a 2D or 3D fix. • Receiver Not Usable-the receiver is unusable, possibly due to interference or abnormal satellite conditions. Turn the unit off and back on to reset. • Simulating GPS-the receiver is in Simulator Mode. GPSMAP 296 Pilot's Guide 5
