APPENDICES
Included below are words that are used quite frequently. Knowing the meaning of them
will make your navigation more fun, and the use of the Multi-Navigator even easier.
Global Positioning System (GPS) – GPS has more than 24 operating satellites around
the Earth. Each satellite provides the precise timing used by the GPS receiver in the
Multi-Navigator to calculate its position. At most your receiver can view twelve satellites at
any one time due to the location of the satellites relative to the Earth.
WAYPOINT – A position which is stored in memory. A waypoint is stored complete with
latitude, longitude, altitude (based an barometric pressure), time and date along with an
eight character name. Any waypoint can be used as a position to navigate towards.
LEG -- Any two waypoints connected together. Two or more legs can form a route.
ROUTE – A series of legs (up to 99) connected together.
ACQUISITION – When the GPS receiver is collecting satellite data, but has not yet
calculated a position.
TRACKING - When the GPS receiver collects satellite data, has calculated a position,
and is continuing to keep track of acquired satellites.
XTE (Cross Track Error) – The distance you have deviated from the original straight line
of travel when navigating to a waypoint. How far off course you are.
TTG (Time To Go) – The calculated time it will take you to reach the waypoint you are
navigating towards based on your current rate of travel.
BEARING – The direction to a selected waypoint from your current acquired position.
COURSE – The direction you are travelling.
DISCLAIMER
Common sense must be used at all times when navigating with any GPS receiver. The
manufacturer’s navigation equipment should only be considered as a navigational aide.
Please note that the manufacturers policy of continuous improvement may result in
changes to product specification without prior notice.
