Satellite navigation software or GNSS navigation software a category of software that provide positioning services by utilizing data from satellite navigation systems.

Key functions of satellite navigation software usually includes:

  1. Positioning: determining the deviice's precise location using signals from multiple satellites
  2. Route planning: calculating optimized route based on user needs, such as starting point, destination, and travelling mean, et cetera. This functionality could be extended to driving assistent.
  3. Tracking: showing where the tracked object have been. (This functionality relies past positioning data to be stored, so not just the "software" technically).

Additional functions that extends the capabilities of satellite navigation software includes:

  1. Searching: finding locations with addresses or GNSS coordinates (latitude and longitude).
  2. Traffic updates: showing real-time traffic information, enabling the software to suggest a better route during driving.
  3. Offline map: allowing regions of map to be pre-downloaded, enabling usage with minimal connectivity.
  4. Bookmarking: saves locations for later use.

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, water or air.[1]

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.
