Key functions of satellite navigation software usually includes: Additional functions that extends the capabilities of satellite navigation software includes: Hardware-wise, a GNSS receiver is needed to interpret satellite signals and compute the user’s location.
By leveraging data from nearby cellular towers, Wi-Fi, and Bluetooth connections, A-GNSS enhances accuracy, reduces power consumption, lowers the risk of signal blockage, and effectively mitigates the limitations of GNSS.
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.
It may incorporate GRIB weather overlay on the chart, Tide predictions and other related information services of additional use to mariners.
Free and open source This kind of software usually creates a modern glass cockpit and uses more than just a single GNSS sensor to assist the navigation.
