SKG12 series pure BeiDou module serving BeiDou-3 satellite

2024-07-08/ By Admin

Beidou-3 is the world's first satellite navigation system to provide three frequency signal services. The use of dual frequency signals in satellite navigation systems can weaken the impact of ionospheric delay, while using triple frequency signals can construct more complex models to eliminate high-order errors in ionospheric delay and improve the efficiency of carrier phase ambiguity resolution. In theory, this can improve carrier convergence speed. Therefore, the subsequent GPS will also adopt a three frequency signal system.

Beidou-2 provides three public service signals, B1I, B2I, and B3I, in the B1, B2, and B3 frequency bands. The center frequency of the B1 frequency band is 1561.098MHz, B2 is 1207.14MHz, and B3 is 1268.52MHz. Beidou-3 provides five public service signals, namely B1I, B1C, B2a, B2b, and B3I, in the B1, B2, and B3 frequency bands. The center frequency of the B1 frequency band is 1575.42MHz, B2 is 1176.45MHz, and B3 is 1268.52MHz.

The BeiDou navigation and positioning module developed based on BeiDou satellite can better meet market demand, achieve higher positioning accuracy with the support of BeiDou satellite, and also have strong anti-interference performance. The SKG12 series pure BeiDou module products developed by SKYLAB are as follows:

SKG12DI-02H Product Introduction

SKG12DI-02H is a Beidou dual frequency integrated navigation and positioning module developed by SKYLAB, which only receives signals from Beidou navigation satellites (including Beidou-2 and Beidou-3). This module integrates 3-axis accelerometers and 3-axis gyroscopes for multi-source information fusion, combined with BeiDou positioning technology and inertial navigation technology. In environments with poor or even lost BeiDou signal quality, it can still continuously output positioning data, providing continuous and accurate positioning services for navigation and positioning applications.

Widely used in vehicle navigation, vehicle networking, intelligent cockpit, location tracking, vehicle networking, logistics tracking and other scenarios.

SKG12D-09A Product Introduction

SKG12D-09A is a dual frequency positioning and navigation module launched by SKYLAB that only receives signals from Beidou navigation satellites (including Beidou-2 and Beidou-3). Internally integrated with a baseband RF integrated SOC chip, it can support BDS B1I+B1C+B2A frequency points and fully support the Beidou three signals, providing users with strong anti-interference, low power consumption, and high-quality positioning and navigation solutions.

SKG12D-09A adopts an industry standard packaging of 12.2mm * 16mm. Production complies with IATF16949, and module reliability testing complies with ISO 16750.

Supports A-BDS assisted positioning, supports raw observation output (RTCM3.3 protocol), and supports simultaneous operation of BDS BII+B1C. Supports power supply to active antennas, with functions such as antenna status detection and interference detection alarms.

SKG12S-09A Product Introduction

SKG12S-09A module is a Beidou positioning and navigation module launched by SKYLAB. The module integrates SKYLAB's independently developed SOC baseband and RF integrated BeiDou chip, fully supporting the BeiDou three signals, and providing users with strong anti-interference, low power consumption, and high-quality positioning and navigation solutions.

In order to meet the demand for compact and fast installation of positioning terminal products, we have reduced the module volume during product design. The module size is 16.6mm x 12.2mm x 2.2mm and is packaged with a 24 pin stamp hole. Production complies with IATF16949, and module reliability testing complies with ISO16750.

The Beidou module integrates power management functions internally, with built-in SAW and LNA. Supports BDS B1I/B1C frequency points, supports BDS single-mode operation, supports A-BDS auxiliary positioning, supports power supply to active antennas, has antenna status detection function, and has interference detection alarm function.
