Active-Log Working memory of Garmin GPS receivers where the current track recording is stored.
Altitude Profile Difference of altitude of a tour is viewed. It is generated automatically by uploading a tour to our website.
COM-Port Comuters' serial interface. COM-Port (COM 1, COM 2,...) is the identification for serial interfaces on computers.
Coordinates A set of numbers that describes your location on or above the earth. Coordinates are typically based on latitude/longitude lines of reference or a global/regional grid projection (e.g., UTM, MGRS, Maidenhead).
Data cable Connection between GPS devices and computers.
DGPS Differential GPS. An extension of the GPS system that uses land-based radio beacons to transmit position corrections to GPS receivers. DGPS reduces the effect of selective availability, propagation delay, etc. and can improve position accuracy to better than 1 meter.
GPS Global Positioning System. A global navigation system based on 24 or more satellites orbiting the earth at an altitude of 12,000 statue miles and providing very precise, worldwide positioning and navigation information 24 hours a day, in any weather. Also called the NAVSTAR system.
Latitude A position's distance north or south of the equator, measured by degrees from zero to 90. One minute of latitude equals one nautical mile.
Longitude The distance east or west of the prime meridian (measured in degrees). The prime meridian runs from the north to south pole through Greenwich, England.
PC-interface cable see data cable.
Route A group of waypoints entered into the GPS receiver in the sequence you desire to navigate them.
Serial communication The sequential transmission of the signal elements of a group representing a character or other entity of data. The characters are transmitted in a sequence over a single line, rather than simultaneously over two or more lines, as in parallel transmission. The sequential elements may be transmitted with or without interruption.
Tour profile An overview of a tour with waypoints.
Tour radar A view of 20km surroundings of a tour's center.
Track Your current direction of travel relative to a ground position (same as Course Over Ground).
Track point A point which describes coordinates and sea level.
USB-interface Universal Serial Bus: computer link for fast data submission between computer and devices.
WAAS Wide Area Augmentation System. A system of satellites and ground stations that provide GPS signal corrections for better position accuracy. A WAAS-capable receiver can give you a position accuracy of better than three meters, 95 percent of the time. (At this time, the system is still in the development stage and is not fully operational.) WAAS consists of approximately 25 ground reference stations positioned across the United States that monitor GPS satellite data. Two master stations, located on either coast, collect data from the reference stations and create a GPS correction message.
Waypoint Waypoints are locations or landmarks worth recording and storing in your GPS. These are locations you may later want to return to. They may be check points on a route or significant ground features. (e.g., camp, the truck, a fork in a trail, or a favorite fishing spot). Waypoints may be defined and stored in the unit manually by taking coordinates for the waypoint from a map or other reference. This can be done before ever leaving home. Or more usually, waypoints may be entered directly by taking a reading with the unit at the location itself, giving it a name, and then saving the point. Waypoints may also be put into the unit by referencing another waypoint already stored, giving the reference waypoint, and entering the distance and compass bearing to the new waypoint.
