Data sheet

The L76K multi-satellite positioning system is a multi-satellite system (GPS, BeiDou, GLONASS, QZSS) that supports joint multi-system positioning and independent single-system positioning.

It also supports the AGNSS function and incorporates a low-noise amplifier and surface filter, giving users of the GNSS module a fast, accurate and high-performance positioning experience.

Compared with a single GPS system, the multi-satellite positioning system significantly increases the number of visible and usable satellites, improves positioning accuracy and enables stable, high-accuracy positioning even in complex urban environments.

It supports the AGNSS function, which significantly reduces the time required for initial positioning, and the integrated low-noise amplifier provides high sensitivity, high-precision positioning and fast signal capture and tracking, even in weak signal conditions, which also ensures good positioning performance.

The integrated surface acoustic filter greatly enhances the module's anti-interference capability, and the active antenna detection circuit and protection circuit are integrated internally to protect the module and active antenna from damage.

The display uses a 1.54-inch "electronic paper" with front light, 200x200 resolution and can be used in a dark environment.
