Tips on Satellite Signal Reception The signals received from the satellites are extremely weak and getting a good "view of the sky" is important to any GPS receiver. However, the GPS Companion uses 12-channel technology to overcome a lot of the lost signals due to poor or blocked view of the sky. Early GPS receivers were notorious for losing lock (not being able to compute a position fix) in seemingly mild conditions. If you owned one of these receivers you are going to love the way the GPS Companion performs. [. . . ] However, the time transmitted is GMT (Greenwich Mean Time) and requires an offset to adjust it to your local time. This offset and DST (Daylight Savings Time) flag are set during initialization but can be changed at any time. GPS Interval GPS Interval is adjusts the rate that the Navigation, Satellite and Sky Chart screens are updated. GPS Messaging This window displays the string of NMEA data that is received to your Palm organizer from the Map Companion. Start GPS This button starts the GPS communication between GPS Companion and the Map Companion. It is used only if the Stop button has been pressed. Stop GPS This button stops the GPS communication between the GPS Companion and the Map Companion software. Set Time The Set Time button sets your Palm organizer's time & date to that received in the satellite signals. Note: The GMT deviation and DST must be set correctly for this to work properly. Initializing the GPS Since the satellites are constantly rotating the earth, the GPS Companion wants to know approximately where it is located, the date and the time. This information isn't mandatory, the GPS Companion can "poll" the sky looking for satellites and eventually get the information it needs but this takes time. So to speed up this process the GPS Companion has a built in almanac of all the satellites and where they will be at any given time for all positions. So now with the approximate location and time, the GPS Companion just refers to its almanac and can immediately begin receiving satellite data. Well, every time the GPS Companion computes a fix it is stored in memory. (Only the last fix computed is stored, not all of them. ) The next time it is turned on and needs to start computing a fix, the GPS Companion uses this last fix as a starting point. What if the GPS Companion has never taken a fix or if it has been moved (more than 500 miles) since the last time it took a fix?In this case, to speed up the TTFF (time to first fix) you should access the Initialization Screen in the GPS Mode and enter the Lat/Lon for your position. Therefore, the maps are only as accurate as the original source we purchased or licensed, and are not meant to be used for high-precision measurement or navigation applications requiring highly accurate measurements of the earth's surface. The maximum positional accuracy error claimed by our current source data provider is approximately 150 feet but in practice we have found the errors to be on the average of about 20 feet. As much as we would like to, we cannot guarantee that all existing roads are present in the map data because our sources do not guarantee it to us. Maps vary in age, and older cities like New York, for example, are unlikely to have any missing streets at all. Newer, fast-growing cities are more likely to be lacking some streets. #$K North America GMT Reference Chart Area Atlantic Eastern Central Mountain Pacific Alaska Hawaii Time Zone GMT Deviation -4 GMT Deviation (DST) EST CST MST PST -5 -6 -7 -8 -9 -10 -4 -5 -6 -7 Example: If the GMT is 1300 and you are in the PST and not observing DST (daylight savings time) then your local time would be 0500.

Starting NAV Companion Tap the NAV Companion application icon from the list of applications on your organizer. If this is the first time you have used the Map Companion software, you will be prompted to initialize the receiver. For information on initialization, see Initializing the GPS. To prevent accidental battery drain, the NAV Companion application program will exit after 30 minutes if : A. a position fix has not been computed or B. position fixes are being computed but there is no indication of movement.

This information isn't mandatory, the GPS Companion can "poll" the sky looking for satellites and eventually get the information it needs but this takes time. [. . . ] Each waypoint has a checkbox next to its name. Tapping on the checkbox changes the status of the waypoint, (checked is displayed and unchecked is hidden). Addtionally you can hide or show all of the waypoints in the list by selecting the desired option from the menu bar. Tap on the Menu icon and tap on Waypoints from the menu bar. You now have the option of hiding all of the waypoints (tap on "Hide All" ) or displaying all of the waypoints (tap on "Show All"). Deleting Hidden Waypoints You can easily delete all waypoints that you have marked as hidden (see Hiding & Showing Waypoints). [. . . ]
