Glossary

Find out in detail about what the most common technical terms mean so that you can fully appreciate the wide range of possibilities offered by our products:

Technical features

ANT+™: Technology enabling you to save and transfer information about heart rate, speed and cadence in real time thanks to ANT+™ external sensors.

Bluetooth: Technology capable to scan and detect bluetooth receptors as well as derive audio connection between a device and bluetooth headsets.

GPS/GLONASS: TwoNav is compatible with two satellite positioning systems: GPS (the US system) and GLONASS (the Russian system).

IP certification: the IP protection class refers to the IEC 60529 (Degrees of Protection 1) international standard for electronic devices.

Touch screen: Screen allowing you to enter data and instructions by touching its surface.

Transflective screen: Liquid crystal display (LCD) that reflects and transmits light (transflective = transmissive + reflective). Under bright illumination the screen acts mainly es a reflective display. Only in dark ambient situations an auxiliary transmissive backlight needs to be provided.

Basic concepts of navigation

Autoroute: TwoNav can be configured to calculate a route from your current position to a user-selected destination. TwoNav will calculate the best route automatically, in accordance with the user's preferences.

Data field: While navigating, TwoNav saves data of interest constantly. This information (data fields) is often very useful for analysis and comparison (speed, height, distance, etc.).

Bearing: Bearing data determines the orientation of the map when the function ‘Orient map: Track up’ is enabled. TwoNav offers you different ways to determine the bearing you are taking during your navigations.

Coordinates: Geographical position of the waypoint.

Data page: Data pages offer an additional place for you to review lists of data fields.

Geocaching: Geocaching is an outdoor treasure hunting game that uses GPS devices. Participants navigate to a specific set of GPS coordinates (the geocache) and attempt to find a container hidden at that location. This container may include a reward for the participant.

Lap: Laps are equal divisions of the track split based on a default interval set by you.

POI: POIs (Points Of Interest) are waypoints grouped into categories of different types of services that may be useful during outdoor navigations (hotels, restaurants, campsites, fuel stations, transports, stores...).

Roadbook: A roadbook is a diagram tool commonly used by rally co-drivers and walkers that help them to navigate uncertain terrains. Traditional roadbooks contain several pages of information such as charts, GPS coordinates, written instructions, manoeuvres...

e-Roadbook: e-Roadbooks contain all this information in digital format with no need to read indications in a book, TwoNav will display all manoeuvres on the screen.

Route: A route is a group of waypoints ordered in a predetermined way. It is a way of navigating that allows for planning a course from one place to another going through various waypoints. Routes are used when it is not possible to reach a place in a direct way (in straight line).

Track: A track is a group of points ordered by time, where each point contains information on the position, time and date, coordinates and, in most cases, altitudes.

Trackattack: TwoNav can use a previous track as a reference to compare your current performance. Choose a track and start the navigation. A simulation of that track will be played at its original speed, so you can compete against it (‘Virtual Coach’). Trackattack is based on two pointers: your current position and an additional pointer, the ‘Virtual Coach’. Try to improve your results by comparing your current and past performances on map or in graphs in real time.

Trackback: The currently recorded track up to this moment is inverted, so you can navigate it in reverse.

Triplog (record itinerary): 'Triplog' is the command you use to manage the recording of routes. Routes are recorded when the 'Triplog' function is activated.

Waypoint: The waypoint is a point defined by a geographical position, latitude and longitude coordinates and in most cases altitude, used by the GPS navigation tools. Waypoints are represented on screen as points with name or representative icon.

Types of maps

3D relief map: Maps digitally calibrated based on elevation reliefs containing information related to the altitude of the ground. 3D+ mode can only be displayed with a relief map loaded.

Cadastre map: Maps containing information related to limits of all terrain parcels (fields, roads, buildings...).

Contour line: Line linking points at the same altitude.

Locked map: Maps not activated (in order to start working with them, a license code is required).

Marine chart: Maps containing nautical information related to the sea (depth data, ports, marine services, tides, currents, marine wrecks...).

On-line map: Remote maps only accessible if internet connection is provided.

Orthophoto: Maps containing aerial photographs with information related to all elements included in the landscape (fields, lakes, roads, buildings, national parks...).

Raster map: Map digitally calibrated based on bitmap images (if map is scaled, there will be loss of clarity, the quality of the map will degrade).

Resolution: Relation between the distance of the ground in meters and a pixel (meters/pixel). A fewer number will represent a more detailed map.

Scale: Ratio of the distance between two points as shown on the map and the actual distance on the ground.

Topographic map: Maps containing information related to the relief of the terrain (elevation contour lines, pathways, national parks...).

Urban map: Maps containing information related to roads and streets (names of the streets, street directions, points of interest...).

Vectorial map: Maps digitally calibrated based on vectors (if map is scaled, there will be no loss of clarity, the quality of the map will not degrade).
