Allystar TAU1103 GNSS module
TAU1103 GNSS module
TAU1103 is a cost-effective GNSS positioning module that is based on an HD8020 series GNSS chip. It supports GPS/QZSS, Galileo, and GLONASS. With a compact size and high integrated design, TAU1103 is easy to apply to navigation applications, especially friendly to a solution requiring a strict cost.
Feature
- Low power consumption design
- Active antenna short circuit protection and open circuit detection
- Supports single-system independent positioning and multi-system positioning
- State-of-art low power consumption
- Supports A-GNSS feature
- Compatible with mainstream GPS modules
