Key Features
- Simultaneous multi-constellation reception of GPS, Galileo, GLONASS, BeiDou-2, and QZSS maximizes satellite visibility and positioning accuracy down to 1.5 m CEP
- Integrated RF front end and 4 MB in-package Flash eliminates external RF filter and code storage components, reducing BOM and PCB area
- Tracking sensitivity of -165 dBm enables reliable positioning in challenging indoor and urban canyon environments
- Compact BGA package supports miniaturized GNSS module designs for wearable trackers, asset monitoring, and IoT devices
Applications
STA8090F4G is designed for high-accuracy positioning in automotive telematics, fleet management systems, and industrial asset trackers where simultaneous GPS, GLONASS, Galileo, BeiDou-2, and QZSS reception provides robust satellite coverage globally. The integrated RF front end and on-chip Flash allow a compact single-chip GNSS solution on constrained PCB areas in handheld devices and wearables. Its -165 dBm tracking sensitivity also supports pedestrian navigation applications in dense urban environments where sky view is partially obstructed.

Frequently Asked Questions
Which GNSS constellations does STA8090F4G support simultaneously?
STA8090F4G simultaneously receives GPS (L1 C/A), Galileo (E1), GLONASS (L1), BeiDou-2 (B1), and QZSS signals. This 5-constellation support provides access to over 100 satellites globally, delivering position accuracy down to 1.5 m CEP and improving reliability in environments with limited sky view.
What is the tracking sensitivity of STA8090F4G, and how does it benefit urban navigation?
STA8090F4G achieves a tracking sensitivity of -165 dBm, enabling it to maintain satellite lock in urban canyons, near building obstructions, and in light indoor environments. Acquisition sensitivity is -145 dBm, allowing cold-start fix acquisition typically within 29 seconds under open-sky conditions.
How does the in-package 4 MB Flash of STA8090F4G reduce system BOM complexity?
The 4 MB of Flash integrated within the STA8090F4G package stores GNSS firmware and almanac data without requiring an external SPI Flash chip. This eliminates at least one component and its associated decoupling network, reducing BOM count by 3 to 5 parts and freeing approximately 10 mm² to 15 mm² of PCB area.
For which automotive or industrial temperature ranges is STA8090F4G qualified?
STA8090F4G is specified for operation over the industrial temperature range of -40°C to +85°C, making it suitable for automotive telematics units, fleet management terminals, and outdoor industrial asset trackers exposed to harsh environmental conditions without the need for additional thermal management.
