The anti-spoofing can be customized as the clients' requirement.
Introduction
M20 is a high-precision RTK positioning module, it has 54 pins with package of LGA. The high-precision measurement engine, navigation engine and functional safety processor are integrated in the module. It supports the anti-jamming of 65 dBc narrowband, full-constellation and full-frequency RTK solution to deal with harsh environments such as satellite signal interference and multipath. It can provide continuous, real-time and reliable high-precision position and can be applied to automated driving, drones, precision agriculture, surveying, mapping, etc.
Technological Advantage
Full Constellation&Frequency GNSS Signal Reception
It supports BDS/GPS/GLONASS/Galileo/QZSS Full Constellation & Frequency highprecision RTK solution. And the built-in REAL (Ransac Enhanced Advanced
Location) GNSS positioning engine has integrity monitoring to improve the fault
tolerance and fixed solution rate under multipath and interference conditions in urban
area, it can provide more stable and accurate results.
High-performance Multiple Interference Suppression*
SAIF（Smart Advanced Interference Defense), the high-performance multiple interference suppression technoloy with high AD quantization bits, is built in and capable of handling different interferences such as single-frequency, multitone, sweeping, pulse, narrowband with interference-signal ratio of 65 dBc. It can deal with vehicle anti-tracking equipment, radar/airport signal towers etc. and greatly improve the availability and integrity of high-precision positioning in vehicle scenarios.
L-Band*, CLAS*, B2b (PPP)* and E6 (HAS)*
It supports L-Band* SBAS signal reception, can provide 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, fully utilizing 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 ISO26262 ASIL B functional safety requirements. With built-in functional safety GNSS SoC Alice and algorithm, high-precision position, velocity and time with system-level functional safety can be provided for intelligent vehicles and autonomous driving.
