What does GNSS required mean?

What does GNSS required mean?

GNSS stands for Global Navigation Satellite System, and is the standard generic term for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage. This term includes e.g. the GPS, GLONASS, Galileo, Beidou and other regional systems.

What are GNSS devices?

GNSS stands for Global Navigation Satellite System and is used to describe any satellite navigation system with global coverage. Satellite navigation systems relay highly accurate geolocation information to GNSS devices and receivers to determine your current location.

Is GPS the same as GNSS?

GNSS (or Global Navigation Satellite System) is a broad term encompassing different types of satellite-based positioning, navigation and timing (PNT) systems used globally. GPS (or Global Positioning System) is one such type of Global Navigation Satellite System.

What is GNSS test?

A GNSS simulator reproduces the environment of a receiver by modelling vehicle and satellite motion, signal characteristics, and other effects. Effective use of a simulator is the most valuable tool in GNSS receiver testing.

What do you need to know about the GNSS driver?

GNSS device/engine: This is a conceptual component that encapsulates the SoC and hardware pieces of the GNSS device. An IHV may choose to implement most of the GNSS functionality within this component, thus making the GNSS driver layer very thin (essentially an adapter for interfacing with the GNSS device).

How does the GNSS adapter work on a satellite?

The GNSS adapter opens a file handle to the GNSS driver using the CreateFile API, then wraps the GNSS native APIs calls into appropriate DeviceIoControl calls, maintains the state machine with the GNSS driver object, and maintains the state of the various incoming requests from the upper layers.

How does the GNSS positioning engine work in the location service?

The GNSS positioning engine component of the location service implements the COM class that exposes the IGnssAdapter interface. The location service exposes a factory mechanism to test and other out-of-process applications for instantiating a singleton COM object of the GNSS adapter COM class within the location service.

Can a GNSS driver support native geofence tracking?

If the hardware does not support native geofence tracking, the GNSS driver must not attempt to implement it at the driver layer. The GNSS engine must also expose documented IHV-specific tuning parameters to enable finding the right balance between power consumption and user experience.
