Product Description:

M20 GNSS High-precision Module

Full Constellation & Frequency Anti-jamming L-Band

Introduction

The M20 is a high-precision RTK positioning module comprising 54 pins and housed in an LGA package.
The module incorporates a high-precision measurement engine, a navigation engine and a functional safety processor. It is capable of supporting anti-jamming of 65 dBc narrowband, full-constellation and full-frequency RTK solutions, thereby enabling the module to function effectively in challenging environments such as those characterised by satellite signal interference and multipath. The module is able to provide continuous, real-time and reliable high-precision positioning, and can be applied to a range of fields including automated driving, drones, precision agriculture, surveying, mapping and more.

Technological Advantage

• Full Constellation&Frequency GNSS Signal Solution
The device is equipped with a BDS/GPS/GLONASS/Galileo/QZSS Full Constellation & Frequency high-precision RTK solution. Additionally, the integrated Bynav REAL (Ransac Enhanced Advanced Location) GNSS positioning engine incorporates integrity monitoring, enhancing fault tolerance and fixed solution rate in urban areas. This is particularly beneficial in situations where multipath and interference conditions are present. The result is a more stable and accurate solution.
• High-performance Multiple Interference Suppression SAIF (Smart Advanced Interference Defense) is a high-performance multiple interference suppression technology with high AD quantization bits. It is built in and capable of handling different interferences, including single-frequency, multitone, sweeping, pulse, and narrowband, with an interference-signal ratio of 65 dBc. SAIF can effectively address vehicle anti-tracking equipment, radar/airport signal towers, and other sources of interference, thereby enhancing the availability and integrity of high-precision positioning in vehicle scenarios.
• L-Band, CLAS, B2b (PPP)* and E6 (HAS)*
The device is capable of receiving L-Band* SBAS signals and provides high-precision positioning in environments where conventional differential services or mobile communication services are unavailable. It supports BeiDou-3 B2b PPP* and E6 HAS* solutions, utilising the four-frequency signals from BeiDou and Galileo to significantly improve PPP convergence speed and enhance the availability of high-precision positioning.
• Functional Safety ASIL B The design is based on ISO 26262 ASIL B functional safety requirements. It incorporates a built-in functional safety GNSS SoC, namely Alice, and algorithm, which enables the provision of high-precision position, velocity and time data at the system level, thus facilitating the development of intelligent vehicles and autonomous driving technologies.
