SKG12MR-06A Dual-Band Full-Constellation RTK Positioning Module

2026-04-23/ By Admin

In applications such as precision drone operations, high-precision vehicle navigation, and handheld RTK surveying, positioning accuracy and reliability directly determine the core value of the device. Traditional single-band, single-system modules are prone to ionospheric delay and multipath effects in complex environments, resulting in noticeable positioning jitter that fails to meet centimeter-level requirements. On the other hand, high-end multi-band RTK modules are often bulky and power-hungry, limiting their use in compact devices. How can you achieve dual-band, multi-system, centimeter-level RTK positioning under the constraints of small size and low power consumption? The SKG12MR-06A dual-band full-constellation RTK module delivers the ideal answer.

1. Why Do You Need a Dual-Band Multi-System RTK Module?

• Ionospheric Delay Error: Single-band signals experience delays through the ionosphere that cannot be fully corrected. Dual-band signals can effectively correct these errors by combining observations, significantly improving positioning accuracy.
• Satellite Availability: Multi-system joint positioning (GPS + BeiDou + Galileo + QZSS) doubles the number of visible satellites, ensuring high availability even in urban canyons or under tree cover.
• Centimeter-Level Requirements: Precision agriculture, drone mapping, and autonomous driving demand horizontal errors below 2 cm – something traditional single-point positioning cannot achieve.

The SKG12MR-06A meets these demands with dual-band, full-constellation reception and RTK technology.

2. Six Core Advantages – Redefining High-Performance RTK Modules
