Product description

GNSS single-frequency multi-system sub-meter positioning module

GN-401L is a high-performance, multi-system single-frequency GNSS navigation and positioning module, which can simultaneously support receiving GPS, GLONASS, GALILEO and QZSS satellite signals.

There are more stars, faster positioning, and higher accuracy. The wide-area differential GPS augmentation system is supported by default. [S129,S137.... Wide-area increase

Strong Satellite].

The module has a built-in LNA low-noise amplifier and filtering, a dual-feed point antenna, and a wider bandwidth, so that the signal reception distribution is more even when receiving GNSS satellite signals, so as to achieve more stable signal reception performance and achieve high-precision positioning effects. The module is small in size and light in weight, and can be used in industrial applications such as individuals, vehicles, unmanned aerial vehicles, handheld positioning terminals, and individual positioning systems.

The GN-401L module has the application characteristics of low power consumption, high sensitivity, high precision, and low cost. It is the best choice solution to meet the navigation, positioning, timing, aircraft model and other fields, and can meet the strict application requirements of industrial grade. The GNSS module has a compact size, and the surface adopts a 1.0 6PIN connector and a pad design, which can be more convenient for integration.
