The TFGPSLITE02 module is a compact GNSS solution based on the u-blox SAM-M8Q. It is designed for small, lightweight, and simple UAVs, offering excellent positioning accuracy with support for multiple satellite constellations. It connects seamlessly to flight controllers via the Pixhawk standard "Basic GPS Port".
- GNSS Support: Concurrent reception of up to three GNSS systems (GPS, Galileo, GLONASS).
- Compact Design: Compact form factor (15.5 x 15.5 x 6.3 mm) with integrated patch antenna.
- High Sensitivity: Superior performance in environments with weak or obstructed GNSS signals.
- Augmentation Systems: Support for SBAS (WAAS, EGNOS, MSAS, GAGAN) and QZSS.
- Advanced Security:
- Geofencing for operational boundaries.
- Spoofing detection to enhance signal integrity.
- Message integrity protection.
- Wide Operational Range:
- Altitude: Up to 50,000 m.
- Velocity: Up to 500 m/s.
- Dynamic tolerance: Up to 4 g.
- Built-in RTC: Ensures faster Time-To-First-Fix (TTFF) even after prolonged power-off periods.
- Interfaces:
- UART and I2C (via Basic GPS Port).
- Time pulse output (1 PPS, configurable up to 10 MHz).
- Power Supply:
- Main supply voltage: 5 V.
- Typical current consumption 30 mA.
