Key Features
- Simultaneous GPS, GLONASS, Galileo, and BeiDou reception at -162 dBm tracking sensitivity enables reliable positioning in urban canyons and weak-signal environments
- 12 Mbps serial data output rate supports fast position fixes and real-time RTK correction data streaming in precision navigation applications
- 99-ball TFBGA (5x6x1.2 mm, 0.5 mm pitch) enables ultra-compact GNSS module designs in wearables and asset trackers with minimal PCB area
Applications
The STA8090FGTR is targeted at precision IoT asset trackers, automotive telematics units, and industrial survey equipment requiring simultaneous multi-constellation GNSS reception at -162 dBm sensitivity. Its 1.2 V supply and thin TFBGA package are ideal for wearable GPS devices, drone autopilot systems, and handheld field computers where board space and power budget are tightly constrained. Transportation logistics applications rely on it for accurate real-time position reporting across all major satellite constellations to ensure coverage globally.

Frequently Asked Questions
Which GNSS constellations does the STA8090FGTR support, and how does multi-constellation reception improve accuracy?
The STA8090FGTR simultaneously tracks GPS, GLONASS, Galileo, and BeiDou signals, giving access to over 100 satellites across 4 constellations. This redundancy reduces position dilution of precision (PDOP) to below 1.5 in open-sky conditions and maintains sub-5-meter accuracy in urban environments where single-constellation receivers can lose lock entirely.
What tracking sensitivity does the STA8090FGTR achieve, and why does it matter for in-building asset tracking?
The STA8090FGTR achieves -162 dBm tracking sensitivity, which is approximately 10 dB better than standard consumer GNSS chips at -152 dBm. This extra sensitivity allows position fixes inside warehouses and parking structures where typical GNSS receivers fail, making the device suitable for indoor-outdoor asset tracking solutions that must maintain continuous position updates without switching to Wi-Fi or cellular fallback.
What are the package dimensions of the STA8090FGTR, and how do they constrain PCB layout for a miniature tracker module?
The STA8090FGTR uses a 99-ball TFBGA measuring 5 mm x 6 mm x 1.2 mm with a 0.5 mm ball pitch, requiring at least 4 PCB layers for full signal and power routing escape. The fine 0.5 mm pitch necessitates solder mask defined (SMD) pads and precise solder paste stencil apertures of approximately 0.25 mm diameter to achieve reliable reflow assembly at 260°C peak temperature.
How does the STA8090FGTR's 12 Mbps output interface support RTK correction data in a precision agriculture application?
With a 12 Mbps serial data output, the STA8090FGTR can receive and apply RTCM 3.x correction messages at rates up to 10 Hz without data latency, enabling centimeter-level RTK positioning in agricultural GPS guidance systems. The high throughput also supports concurrent NMEA position streaming to a host processor while logging raw satellite measurement data for post-processing differential GNSS at sub-10 cm accuracy.
