Button Layout Map Page Download MapSource maps for greater detail. Press Menu button once to open Map Setup. Set map display preferences as desired. Use Map to visually monitor track log collection. Download a new almanac if GPS receiver is new, has been moved more than 300 miles while turned off, or has not been used within the last 30 days. Turn receiver on and place in location with clear view of sky. Allow up to 15 minutes for a new almanac to download after receiver acquires first satellite signal. The almanac is automatically updated whenever the receiver is in use. Electronic Compass Page Press Menu button once to open Compass Setup menu.

Press Enter button to select. Do not select Wrap When Full. From Main Menu, select Track Logs. Press Menu button to open Track Log Menu. Download and archive active log (if needed). Press and hold Enter button to create a new waypoint. Do not edit date/time field (this information is needed for GIS). Select Ok and press Enter button to save waypoint. Or press Menu button once to access waypoint options menu. • The NWCG GPS standard is datum NAD83(same as WGS84) and lat/longcoordinatesystem in degrees, minutes and seconds. • Briefing • Plan mission to achieve the objectives. • Are mission logistics defined to execute and complete the mission? • Delivered GPS data or product format is understood.Equipment • Select appropriate GPS receiver for the mission. • Use an external antenna whenever possible. • Adequate batteries or power source. • Paper map and compass. • Notebook and pencils. • GPS metadata form. • Prepare GPS receiver • Set datum and coordinate system to NWCG (see above) or incident standard. • Update receiver almanac for the local area. • Download and delete old waypoints, active log and saved tracks if not needed to clear memory. • Set up Track Log collection interval based on method of travel and speed, and size of area to be mapped. • Check wires, connections and power source. • Verify all GPS settings are correct prior to mission. • Aerial mapping mission • Brief pilot on mission prior to takeoff. • Ensure reliable external antenna connection. • Carry spare GPS receiver and extra batteries as backup. To pause logging, set Recording to Off. When mapping mission is complete, either turn GPS receiver off or save track log (saving log provides area calculation). Tracks page displays percentage of memory used. Clear Active Log and saved Tracks to free up memory. Select Setup Track Log. Press Enter button once. Monitor memory usage to ensure adequate free memory to complete the mission. Record Mode set to OFF for setup. Set Interval to Time. Set Interval Value based on method of travel during data collection, and size of area to be mapped. A total of 10,000 track points are available. Mark waypoint. Name waypoint if needed. Do not edit date/time field. Press Menu button once to open Waypoint Options menu. After collecting a perimeter track log, save active log. Up to 10 tracks may be saved. Open a saved Track Log from the Tracks page. Area format can be Select Average Location and press Enter button once. Averaging begins automatically. Approximate log times (start with empty Track Log): One second interval: 2.7 hours total log time. Three second interval: 8.3 hours total log time. Five second interval: 13.8 hours total log time. Suggested logging rates (based on speed of travel): Helicopter: 1 - 3 second log interval. Walking: 5 - 10 second log interval. Vehicle: 3 - 7 second log interval.Logging interval may be changed during mission. changed. Select “ac” for acres (as shown).Caution: when mapping any perimeter, do not close polygon at the same point the track log was started. Doing so may create overlapping track points, which may cause an area miscalculation, as well as data problems in GIS. Note position count for each waypoint on metadata form. Select and press Save when done. Positions will be averaged into a single waypoint. Back Side
