White Paper

The MAX-7 series of standalone GNSS modules is built on the exceptional performance of the u‑blox 7 multi-GNSS (GPS, GLONASS, QZSS and SBAS) engine. The MAX-7 series delivers high sensitivity and minimal acquisition times in the ultra compact MAX form factor. The MAX-7 series provides maximum sensitivity while maintaining low system power. The MAX-7C is optimized for cost sensitive applications. The MAX-7Q provides best performance and lowest power, while the MAX‑7W provides best performance and is optimized for active antennas. The industry proven MAX form factor allows easy migration from MAX-6 modules. Sophisticated RF-architecture and interference suppression ensure maximum performance even in GNSS-hostile environments. The MAX-7 series combines a high level of integration capability with flexible connectivity options in a miniature package. This makes it perfectly suited for industrial and mass-market end products with strict size and cost requirements. The DDC (I2C compliant) interface provides connectivity and enables synergies with u‑blox cellular modules. u‑blox 7 modules use GNSS chips qualified according to AEC-Q100 and are manufactured in ISO/TS 16949 certified sites. Qualification tests are performed as stipulated in the ISO16750 standard: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”. MAX-7Q complies with green/halogen free standards.
