8-28.1 BAR GRAPH DISPLAYThe GPS 95 continually monitors thestatus of the satellites it tracks andshows that information graphically on aBar Graph Display. Satellite numbers(1-32) are represented along the bottomof the graph; signal strength (1 to 9,weakest to strongest) is representedalong the side. Once a satellite isreceived, a bar is displayed showingsignal strength for that satellite. If a satellite is visible, but not being received,the signal strength will be blank.The receiver status is also shown at the top of the page. In this example, theunit is acquiring satellites. The following is a list of possible receiver statusmessages:“Searching the Sky” The GPS 95 is in the process of searching thesky for visible satellites. You will also beinformed of this condition with a “Searchingthe Sky” message.“Acquiring Satellites” The GPS 95 is in the process of acquiringvisible satellites.“2D Navigation” The GPS 95 is in the 2D navigation mode.The unit will calculate a horizontal position,but not altitude.“3D Navigation” The GPS 95 is in the 3D navigation mode andwill calculate altitude“Simulating Navigation” The GPS 95 is in the simulator mode. Thismode should be used only for practice and tripplanning. Never use this mode for actualnavigation.“Poor Coverage” The GPS 95 is unable to acquire sufficientsatellites for navigation.“Need Altitude” The GPS 95 needs altitude in order to startand/or continue 2D navigation. Go to thePresent Position Page and enter the altitude.(See Section 5.4.)
