Fast-Acquisition Enhanced-Sensitivity
16-Channel SMD GPS Receiver Module
The GPS-31-FS is a miniature 16-channel OEM GPS
receiver module. It is optimized for high-performance,
ease-of-use, flexibility, and low-cost. The GPS receiver is
suitable for a wide range of navigation and tracking
applications.
FEATURES
16 parallel channel GPS receiver
16 parallel channels and 4000+ correlators provide fast
4000+ correlators
satellite signal acquisition and short start-up time. Acquisition
SBAS (WAAS, EGNOS) support
sensitivity of –140dBm and tracking sensitivity of –155dBm
Supports active and passive antenna
offers good performance even under difficult environments.
High Sensitivity:
-140dBm acquisition sensitivity
The GPS-310FS provides one 3.3V UART serial I/O and one
-155dBm tracking sensitivity
GPIO pins. Self-contained LNA supports direct connection to
Fast Acquisition:
passive or active antenna.
< 5 second hot start
Sub-100mW power consumption makes the GPS-310FS
< 35 seconds warm start
ideal for battery-operated portable devices.
< 60 second cold start
Satellite-based augmentation systems, such as WAAS and
5m CEP accuracy
Low Power Consumption, < 130mW
Small Size, 25.4 x 25.4 x 3.4 mm
EGNOS, are supported to yield improved accuracy.
Small size and SMD mounting allow standard SMT assembly
process, making it ideal for high volume production.
