Satellite navigation software

Last updated

Satellite navigation software or GNSS navigation software usually falls into one of the following two categories:

Contents

  1. Navigation with route calculation and directions from the software to the user of the route to take, based on a vector-based map, normally for motorized vehicles with some motorized forms added on as an afterthought. [1]
  2. Navigation tracking, often with a map "picture" in the background, but showing where you have been, and allowing "routes" to be preprogrammed, giving a line you can follow on the screen. This type can also be used for geocaching.

Terminology

Track

A track is a trace of somewhere that you have actually been (often called a "breadcrumb trail"). The GNSS unit (external or internal) periodically sends details of the location which are recorded by the software, either by taking a reading based on a set time interval, based on a set distance, based on a change in direction by more than a certain angle, or a combination of these. Each point is stored together with its date and time. The resulting track can be displayed as a series of the recorded points or a line connecting them.

Retracing your steps is a simple matter of following the track back to the source.

Route

A route is a preset series of points that make up a set route to follow for your destination. Most software allows the route and the track to be displayed at the same time.

Waypoint

Waypoints are used to mark particular locations, typically used as markers along the "way" to somewhere. They are either key entered by users or downloaded from other sources, depending upon the sophistication of the device. Although not linked to tracks or routes, they can be used to simplify the construction of routes, by being able to be re-used. Frequently, waypoints serve a "safety" purpose, enabling a route to be taken around obstacles such as shallow water (marine navigation) or streams/cliffs/other hazards which may prevent a safe passage directly from point "A" to point "B".

Platforms

Software can be used on a laptop computer with an attached GNSS receiver. Most commercial software runs on Windows, Mac OS X, and Linux. Some software like Waze and Google Maps can also be used on mobile phone operating systems.

Software products

There are several navigation software products available. The primary distinction is whether it is designed for use on land or water.

Land-based navigation software

Commercial navigation software with embedded maps
Commercial navigation software with scanned or downloaded maps and orthophotos stored in the computer (independent, stand alone system)
Free open source navigation software (independent stand alone system)
Navigation software with maps downloaded from a remote server

Marine navigation software

Navigation software for use on the water has many features in common with land-based GNSS navigation software. It can use electronic navigation chart or raster charts, usually provides user ability to plan routes and set waypoints, and may have live GPS tracking capabilities. In addition, marine navigation software often has option to control external autopilot for automated boat navigation. It may incorporate GRIB weather overlay on the chart, Tide predictions and other related information services of additional use to mariners.

Aeronautical navigation software

This kind of software usually creates a modern glass cockpit and uses more than just a single GNSS sensor to assist the navigation. Such sensors are Attitude and Heading Reference Systems (AHRS) and Inertial Measurement Unit (IMU) sensors.

A waypoint is an intermediate point or place on a route or line of travel, a stopping point or point at which course is changed, the first use of the term tracing to 1880. In modern terms, it most often refers to coordinates which specify one's position on the globe at the end of each "leg" (stage) of an air flight or sea passage, the generation and checking of which are generally done computationally.

<span class="mw-page-title-main">Automotive navigation system</span> Part of the automobile controls

An automotive navigation system is part of the automobile controls or a third party add-on used to find direction in an automobile. It typically uses a satellite navigation device to get its position data which is then correlated to a position on a road. When directions are needed routing can be calculated. On the fly traffic information can be used to adjust the route.

A point of interest (POI) is a specific point location that someone may find useful or interesting. An example is a point on the Earth representing the location of the Eiffel Tower, or a point on Mars representing the location of its highest mountain, Olympus Mons. Most consumers use the term when referring to hotels, campsites, fuel stations or any other categories used in modern automotive navigation systems.

Traffic reporting is the near real-time distribution of information about road conditions such as traffic congestion, detours, and traffic collisions. The reports help drivers anticipate and avoid traffic problems. Traffic reports, especially in cities, may also report on major delays to mass transit that does not necessarily involve roads. In addition to periodic broadcast reports, traffic information can be transmitted to GPS units, smartphones, and personal computers.

The company was acquired by British firm CSR plc in 2009, who were in turn subsequently acquired by American company Qualcomm on 13 August 2015.

Global Navigation Satellite System (GNSS) receivers, using the GPS, GLONASS, Galileo or BeiDou system, are used in many applications. The first systems were developed in the 20th century, mainly to help military personnel find their way, but location awareness soon found many civilian applications.

Google Maps Navigation is a mobile application developed by Google for the Android and iOS operating systems that later integrated into the Google Maps mobile app. The application uses an Internet connection to a GPS navigation system to provide turn-by-turn voice-guided instructions on how to arrive at a given destination. The application requires a connection to Internet data and normally uses a GPS satellite connection to determine its location. A user can enter a destination into the application, which will plot a path to it. The app displays the user's progress along the route and issues instructions for each turn.

Waze Mobile Ltd, doing business as Waze, formerly FreeMap Israel, is a subsidiary company of Google that provides satellite navigation software on smartphones and other computers that support the Global Positioning System (GPS). In addition to turn-by-turn navigation, it incorporates user-submitted travel times and route details while downloading location-dependent information over a cellular network. Waze describes its application as a community-driven initiative that is free to download and use.

<span class="mw-page-title-main">Turn-by-turn navigation</span> Feature of GPS navigation devices

Turn-by-turn navigation is a feature of some satellite navigation devices where directions for a selected route are continually presented to the user in the form of spoken or visual instructions. The system keeps the user up-to-date about the best route to the destination, and is often updated according to changing factors such as traffic and road conditions. Turn-by-turn systems typically use an electronic voice to inform the user whether to turn left or right, the street name, and the distance to the next turn.

This article contains a list with gratis satellite navigation software for a range of devices. Some of the free software mentioned here does not have detailed maps or the ability to follow streets or type in street names. However, in many cases, it is also that which makes the program free, avoid the need of an Internet connection, and make it very lightweight. Very basic programs like this may not be suitable for road navigation in cars, but serve their purpose for navigation while walking or trekking, and for use at sea. To determine the GPS coordinates of a destination, one can use sites such as GPScoordinates.eu and GPS visualizer.
