GNSSondersteunde
GNSSondersteunde, often translated as GNSS-supported or assisted GNSS, denotes a family of techniques that enhance satellite navigation by combining traditional GNSS signals with auxiliary data provided by external networks or devices. The main goals are to reduce time to first fix (TTFF), improve positioning accuracy, and increase reliability in challenging environments such as urban canyons or indoors.
How it works: A server or network supplies assistance data to the GNSS receiver, including approximate user
Relation to augmentation: GNSSondersteunde overlaps with global augmentation systems such as SBAS or DGNSS, which deliver
Applications and benefits: It is widely used in smartphones, automotive navigation, and IoT devices to achieve
Limitations: GNSSondersteunde depends on network connectivity and data availability; latency and privacy concerns may arise, and
