    However, in many cases, it is also that which makes the program free (and sometimes open source [1]), avoid the need of an Internet connection, [2] [3] [4] and make it very lightweight (allowing use on small portable devices, including smartphones). Very basic programs like this may not be suitable for road navigation in cars, but serve their ...

    Satellite navigation software is most commonly used on mobile devices, particularly mobile phones, to provide the positioning functionality. However, relying exclusively on GNSS data is not accurate enough due to the limitations of GNSS services, To address this, Assisted GNSS (A-GNSS) is used instead.

    A whisk broom or spotlight sensor, also known as an across-track scanner, is a technology for obtaining satellite images with optical cameras. [1] It is used for passive remote sensing from space. In a whisk broom sensor, a mirror scans across the satellite ’s path ( ground track ), reflecting light into a single detector which collects data ...

    A Raymarine chartplotter. A chartplotter is a device used in marine navigation that integrates GPS data with an electronic navigational chart (ENC).. The chartplotter displays the ENC along with the position, heading and speed of the ship, and may display additional information from radar, automatic information systems (AIS) or other sensors.

    When a satellite's orbit is being adjusted, the satellite is marked unhealthy, so receivers do not use it. After the maneuver, engineers track the new orbit from the ground, upload the new ephemeris, and mark the satellite healthy again. The operation control segment (OCS) currently serves as the control segment of record.
