🔧 Key features of the STA1080EOATR
🛰️ Support for multiple GNSS constellations
The STA1080EOATR can process data from multiple global positioning systems simultaneously. This enables higher accuracy and reliability even in urban environments with signal obstructions such as tunnels, bridges, or tall buildings.
🧭 Dead Reckoning integration
It includes interfaces for connecting IMUs and wheel sensors, enabling Dead Reckoning. This maintains accurate positioning even when GNSS signals are lost, such as in underground parking lots or tunnels.
🧠 Built-in computing power
With a built-in microcontroller and dedicated signal processing hardware, it efficiently handles baseband calculations, correction algorithms, and interface tasks.
🚗 Compliance with automotive standards
Compliant with AEC-Q100 standards, making it suitable for automotive environments with temperature fluctuations, vibrations, and electromagnetic interference.
🔌 Typical applications
The STA1080EOATR is widely used in several automotive and industrial applications:
1. In-vehicle navigation systems
Provides highly accurate position data to digital navigation interfaces. Combined with processors such as the STA1079 or TDA series processors, it forms a complete infotainment solution.
2. Advanced driver assistance systems (ADAS)
