Overview The Garmin Vista HCx, brings a high sensitive receiver to Garmins popular line of eTrex handheld units. It features a small GPS receiver and navigator with. Once you press the on. Next it will. retrieve information for the necessary satellites and once it has. While. it seems to be doing the same thing each time it starts there are. Obtaining your first fix is sometimes referred to as initializing. There are several methods of initializing a receiver. EZinit by Garmin to fully. The status screen for. XL is shown at the left. It is similar to the status screen. Garmin units. One of the first things to catch your. These. represent the expected locations for satellites at your location and. The outer circle represent the horizon and the inside circle. Everything inside the inner circle is. Knowing the approximate location and satellite number for. This implies that the unit must already think it knows your. The approximate. location of all of the satellites is stored in the machine in, what is. The almanac provides the data you see on the. GPS receiver by letting it know which satellites. The almanac data is usually good for. However if you leave the unit off for over three months it will have. The Gambler 2014 Soundtrack Free Download. The Garmin emap will display this information but does not. You will need to select gps. The Garmin basic etrex displays very little. Only 4 satellites are. As. the fix progresses on the etrex a light squiggled line will appear as. To understand how this really works you should. Sky. View page. The advanced sky. Garmin receivers. Note that some of the data in this chapter assumes a general. If you. need this knowledge please read the chapter on this subject. The first time you turn you unit on each day it must perform a cold. To perform a successful cold start it must have a current. Given this data the only thing it needs in order to calculate a fix is. D fix or 4 satellites for a 3. D. fix. The data it needs is called ephemeris data and it is. It takes 1. 8 seconds to download this information because it is only. Since your Garmin was turned on at a random. It. would take longer if it had to be received in order but your Garmin is. Once the data has been acquired a position can be computed and. Generally this can be accomplished in an amazing 4. The 4. 5 seconds. After a lock the data will be updated once a second. The older multiplexing receivers cannot achieve such a rapid. The reason is simple, they need to download ephemeris. So it take 9. 0. seconds to download the data from 3 satellites and thus you can expect. D lock in about 2 minutes. After another 3. 0 seconds or so. D lock as it adds in the. If you have a unit that. Once a satellite ephemeris data has been. Since data can be collected in. Since the unit knows it. After. a 2. D fix is produced it can keep track of those three satellites while. D lock. Ultimately the. There is no indication about which 4 it will use at any. The newer 1. 2 channel parallel units can gather data simultaneously. There is no time penalty in doing so. While the G III family, emap, and most other Garmin units continue to. G 1. 2 family and G II no longer uses. Instead. solid bars are used to indicate exactly which satellites in the. Therefore none will turn solid until the first fix is obtained. A. feature of all of the 1. Using more than 4 satellites. Note that the hollowfilled bar feature is not present on all units. Most notably it is missing from the 1. CX color unit and some of the. Warm Starts. If you turn your unit off and back on again you will notice that it is. This is. because it saves the ephemeris data from the last cold start. Saving. this critical data can enable your unit to compute a fix in 1. It needs only to verify that the data is still valid and. The ephemeris data from a satellite is updated every 2 hours at. If the circular orbit is projected to be really close to a. Considering that a satellite makes. Garmin handheld receivers look at the time stamp and use this data. Of course in several hours the satellites you were using may have. Note that the warm. EZinit Starts. The basic etrex does not support EZinit starts. Please skip this. The. basic etrex will attempt a local fix and if this fails it will ask you. This feature. is supported on etrex venture, legend, and vista. If you have moved 5. EZinit. In this case you will seed the unit. This is done on non mapping units by selecting the state or country. This information can be reached by pressing the. You can then scroll through the list of countries and states. Once. you have selected the starting location the unit proceeds as if it. On these Garmin units you may also initialize their position. While the unit is acquiring its position this is a changeable field on. On Garmin units with built in maps the map position can be. Note that these techniques do not. To. use the map follow these steps From the satellite screen, press menu. Initialize Position, press enter. The map screen will. Pressing enter will. EZinit. Autolocate Search the sky. The final method used by your Garmin enables it to find itself and. Omi Game For Windows 7. In autolocate mode. On any of the older. D. fix. On the 1. A 3.

If the unit is doing an autolocate and it fails to produce a 3. D. lock it may prompt you for the altitude reading. You should enter. This. usually happens when the unit has a restricted view of the sky such as. You will likely need an autolocate if you have let the almanac data. You may. need an autolocate if the internal clock is totally wrong although. EZinit will work in this case. Since the etrex, 7. GPSV, and emap do not have an internal battery backup this can occur. Finally you may need an autolocate if you are somewhere in or over the. Under some conditions where. See the chapter on. Undocumented commands to completely clear the unit of all. Completing the Initialization. As soon as you achieve a 2. D lock the unit will switch to the position. You can be navigating at. D lock yet. On some units this can. If it can be selected you still have a 2. D lock. For. older multiplex units and the default settings on the newer twelve. It can be reached by pressing. If the altitude data is selected when you push. D lock. It will remain. D lock is achieved and then the entry will no longer. This can be a handy way to check for 3.

Once a fix is re obtained the track and speed data will. Any break in the track caused by a loss of signal will also. Note that the projected. Loss of a signal for a considerable period will trigger a message to.
