22. Glossary

Active map. The map on a card which is in use

(multiple maps can be on one SD card).

Active route. Shown as a highlighted yellow or

blue line to follow on the map with red arrows

between waypoints.

AOI. An Area of Interest. Consists of a series

of points making up an area of any size or

shape. Can be used to measure an area on a

map, mark various areas of interest, or as an

alternative to the circular POI warning radius.

Arbitrary reference point (for AOIs/LOIs/Grids)

Automatically generated (set) point within or

on an AOI/LOI/Grid. It is used as a reference

point in the following instances:

• As a GoTo point

• As a 'POI' in data boxes

• When using the Pointer

• When using the Centre on Map

button

This reference point can be moved to any new

location by using the

Edit Location by Map

option.

Asc. Abbreviation for ascended height.

Ascents. Positive changes in elevation.

Atomic clock. A type of clock that uses

microwave signals emitted by electrons as its

timekeeping element. It is the most accurate

time standard and is used to control the

frequency of GPS satellite signals.

Bearing. Direction from one object to another.

CEP (Circular Error Probability). Determines

the radius of a circle containing 50% of the

GPS readings.

Cross Track Error. The difference in distance

between a planned route and your location.

Data Box. A white overlay box that appears

in the lower half of the map screen. Shows

customized information about your trip,

environment and map objects. Available as a

2 or 4 box layout.

Descents. Negative changes in elevation.

EGNOS. The European Geostationary

Navigation Overlay Service has been

developed by the European Space Agency

(ESA) for safety of air navigation. It is part of

the Galileo project. When a signal is available

(which is only in the south of England and

mainland Europe), this signal improves the

accuracy of signals from the GPS system.

Electronic compass. Uses magnetic elds to

calculate accurate compass bearings whilst

stationary.

ETA. Estimated Time of Arrival. The ETA is

calculated from the average moving speed if

it is available (see Trip Log). Otherwise the set

speed is used. For example if you have no lock

but the unit previously recorded an average

moving speed which has not been cleared

from the trip log, the ETA will be based on this

average moving speed.

Explorer. 1:25 000 Ordnance Survey map.

Galileo. A planned global navigation satellite

system, being built by the European Union and

European Space Agency as an alternative for

the US Global Positioning System (GPS) and

the Russian GLONASS system. The project is

expected to be completed in 2013.

Geocaching. An outdoor treasure hunt activity

using a GPS to locate hidden containers,

('geocaches'). Often called a "game of high-

tech hide and seek", coordinates, along with

other details of the location, are posted online.

Download les onto your computer from

geocaching.com and use SatSYNC to import

them to the Active 12.

Geotagging. Photos are labeled or 'tagged'

to show where they were taken. Date/time

information from the photos is matched with

the location information from the GPS unit.

(Use the geotagging application in SatSYNC).
