2. Garmin GPSMap 76 $400 12 Channel GPS WAAS enabled 8 MB of Map memory* 1000 Waypoints 10,000 track points 10 hours of battery life Rugged Garmin GPS receivers are fairly inexpensive. The 12 channel GPS units are preferable to the 8 channel units. The additional 4 channels increases the likelihood of �seeing� satellites and increases your accuracy. Waypoints � a GPS term for points. Tracks are lines that can be used in order to: Record where you have been (e.g. where you have surveyed). Measure the area of any space you encompass with a track. Retrace your path. Some receivers have only one location into which all collected data are stored. This receiver has separate containers for recording track information � Active Track, Saved Tracks, Points, Routes. When the Waypoint limit has been reached, you cannot store any additonal waypoints. However, in this instance, you can continue to collect track points. The Garmin GPSMap76 data storage: 1000 waypoints. 10 saved Tracks. Each Saved Track can hold 750 points. Automatic track log, 10,000 points. 50 routes each containing up to 125 waypoints. Garmin GPS receivers are fairly inexpensive. The 12 channel GPS units are preferable to the 8 channel units.

3. Garmin GPSMap 76 Unique Aspects Antenna (Quadrifilar Helix) It Floats Averages waypoints External Antenna (optional) WAAS Differential GPS capable Features specific to the Garmin III+ include: A quadrifilar helix type of antenna. This is probably the most important part of a GPS receiver. This type of antenna allows swiveling for best access to the sky, and can detect satellites close to the horizon. Options with this receiver also allow external antenna options making this model more versatile in aircraft and under canopy. A readily used form factor that allows unit to be placed on flat surfaces for better visibility Allows user to average waypoints for increased accuracy. Other models in the Garmin line like the eTrex are not preferred. Here are some examples why: Patch antenna.

17. Track Log Setup Distance means that a position will be collected after you have traveled the specified distance interval. Note: The units for this function are provided in the Setup Menu, Units, Distance and Speed. The choices are: Nautical feet, Nautical meters, Statue, Metric. If you select Statue then the limitation is hundredths of a mile (52.8 feet). If you select Metric, then limitation is hundredths of a km (10 meters). Time means that a position will be collected after the specified time interval. Note: the minimum is 1 second. Auto means that the software will collect according to the frequency selected (Most Often, More Often, Normal, etc.), with the goal of getting the user back to where the user started. If the user travels slowly it may collect less frequently than when the user travels at a higher speed. If the user is making lots of turns, it may collect more frequently.

19. GPS Data Collection Overview: Power up GPS Allow GPS receiver time to locate satellites (2-5 minutes), longer if new Almanac is needed. Check that GPS is in 3D data collection mode Collect GPS points and/or tracks Record Metadata

20. Downloading a New Almanac An almanac is a kind of log of all GPS satellite positions and health, and allows a GPS receiver to identify which satellites are in its hemisphere, and at what times. An almanac is like a schedule telling a GPS receiver when and where satellites will be overhead. Transmitted continuously by all satellites, the almanac allows GPS receivers to choose the best satellite signals to use in order to determine a position. The almanac is automatically downloaded from satellites whenever a receiver is collecting a GPS signal. An almanac can also be downloaded from a computer, a base station or other archived almanac. The GPS receiver loses it�s almanac when it is not used for a long period of time (more than 30 days). However, the almanac stored in a receiver�s memory becomes outdated fairly quickly (within 2 days) because new information is constantly being uploaded to the satellite constellation from Space Command. The GPS almanac tells a GPS receiver which satellites are functioning, which are �down� (not transmitting), and if there are any new satellites on line (remember that satellites are continuously being replaced). Without an updated almanac, a GPS receiver cannot effectively do its job. There are three ways a GPS receiver can acquire a new almanac: It can automatically download a new almanac once it acquires a single GPS satellite signal. This takes about 12-13 minutes the first time the GPS unit is used. A current almanac can be downloaded from the Internet and uploaded to a GPS receiver via third party software. Global positioning base stations provide the almanac data for the web. An almanac may be swapped among receivers either directly (via a cable link) or by disk and software using a computer.Downloading a New Almanac An almanac is a kind of log of all GPS satellite positions and health, and allows a GPS receiver to identify which satellites are in its hemisphere, and at what times.

21. Downloading a New Almanac with the GPS To download a new almanac, turn on the receiver and find a place with an open view of the sky to facilitate signal acquisition. After the receiver acquires its first satellite signal and has a lock on it (signal strength bar turns solid), it can take up to 13 minutes for the receiver to fully download a new almanac. Thereafter, if you haven�t moved more than 600 miles from your original location, it takes only seconds to minutes to update the almanac. Once an almanac has been downloaded, the receiver should be able to acquire satellites much more quickly in the future if the receiver remains in the same geographic area (within about a 300 mile radius).Downloading a New Almanac with the GPS To download a new almanac, turn on the receiver and find a place with an open view of the sky to facilitate signal acquisition.

22. GPSMap 76 Startup Page The startup page shows the receiver�s status: Acquiring: the receiver is collecting data from satellites, but doesn�t have enough information to calculate a position. 2D Navigation: at least three satellites have been locked on to, but the receiver is only able to provide a two-dimensional position. 3D Navigation: at least four satellites have been locked on to and the receiver is able to calculate a three-dimensional position. If no satellite signals are acquired within five minutes, the receiver will prompt the user to re-initialize the receiver. Signal strength bars show which satellites are being acquired. Hollow bar indicates that the satellite signal has been acquired but not locked on to. Solid bar indicates that the receiver has a good lock on that satellite�s signal. The height of the bars indicate how strong the signal reception is. Sky view graphically shows where the satellites are above the receiver. The receiver is located at the pinpoint in the center of the circles. The inner circle represents an angle approximately 45 degrees above the horizon, and the outer circle represents the horizon. The sky view can be used to get a sense of satellite geometry. GPS Data Collection Wait for 3D mode.
