S1315F8-GL
High-Performance Low-Cost 167 Channel SMD Global Positioning Receiver Module
The S1315F8-GL is state-of-the-art global navigation satellite system receivers capable of using GPS, GPS/GLONSS signal under the same footprint. User can upgrade from GPS navigation system to GPS/GLONASS dual-satellite navigation systems by choosing appropriate model type without hardware redesign.
The -GL12 entry level models offer dual-satellite navigation capability, tracking up to 12 GPS/GLONASS signals combined respectively. Its NMEA output is the same format as GPS receivers, thus users can effortlessly upgrade GPS product to GPS/GLONASS product without needing modification on the application software.
The -GL standard models tracks up to 24 GPS/GLONASS satellite signals combined respectively.
Dual-satellite navigation receiver module receives greater number of satellites than available for GPS-only receivers. The increased satellite number offers superior performance in challenging urban canyon and multipath environments.
The S1315 module contains SkyTraq Venus 8 positioning engine inside, featuring high sensitivity for indoor fix, low power consumption, and fast TTFF. The superior -148dBm cold start sensitivity allows it to acquire, track, and get position fix autonomously in difficult weak signal environment. The receiver’s -165dBm tracking sensitivity allows continuous position coverage in nearly all application environments. The high performance signal parameter search engine is capable of testing 16 million time-frequency hypotheses per second, offering industry-leading signal acquisition and TTFF speed.
The S1315 module contains LNA for easy integration with passive antenna and a SAW filter for increased jamming immunity. It works with both passive and active antenna; the self-contained antenna detection and short circuit protection feature enables lowest integration cost for system integrators using active antenna.
