Vehicular navigation using Global Navigation Satellite System (GNSS) technology such as the U.S. Global Positioning System (GPS) are becoming ubiquitous, with automotive manufacturers provide onboard systems and with several aftermarket systems currently available. However, the GNSS receivers in these systems generally operate autonomously and do not make use of other navigation-related information that may be available, such as from the vehicle's odometers or other onboard sensors. Rather, the GNSS measurements are only integrated with vehicle sensor information after the fact; an approach known as "tight integration".

使用全球导航卫星系统（GNSS）技术（如美国全球定位系统（GPS））的车载导航正变得无处不在，汽车制造商提供车载系统和一些售后系统。然而，这些系统中的GNSS接收器通常是自主运行的，不利用其他可能可用的导航相关信息，例如来自车辆里程表或其他车载传感器的信息。相反，GNSS测量结果仅在事后与车辆传感器信息集成；这种方法被称为“紧密集成”。
