72Section 6GPS ReceiverReferenceEntering Data and Accessing ProgrammingAs you begin to explore the capabilities of the GPSreceiver, learning how to use the GPS programmingallows you to take full advantage of the features.There are three keys that allow you to access pages,menus, and enter data. These are the PAGE, MENU, andENTER keys. Movement from field to field within ascreen display is accomplished using the ARROWkeypad. Use the arrows to cursor to and highlight a fieldon the display, then press ENTER to either enter data orselect from a ‘pop up’ menu. You can use either thephone keypad alphanumeric keys or the ARROWkeypad to enter data in a field. Use the QUIT key tocancel any entry before it is completed.Satellite Status PageThe NavTalk Pilot’s Satellite Status Page provides avisual reference of various GPS receiver functions,including current satellite coverage, receiver operatingmode, battery level and position accuracy. As the receiverlocks onto satellites, a signal strength bar will appear foreach satellite in view, with the appropriate satellitenumber (01-32) underneath each bar. The progress ofsatellite acquisition is shown in three stages:• No signal strength bars—the receiver is lookingfor the satellites indicated.• Hollow signal strength bars—the receiver hasfound the satellites and is collecting data.• Solid signal strength bars—the receiver hascollected the necessary data and the satellites areready for use.Each satellite has a 30-second data transmission thatmust be collected (hollow bar status) before that satellitemay be used for navigation (solid bar status). Once a fixhas been calculated, the unit will then update yourposition, track, and speed by selecting and using the bestsatellites in view.The three stages ofsatellite acquisition
