L1 Quad Constellation
GNSS Receiver Module
The PX1100S is a satellite navigation receiver capable of
using GPS, Beidou, Galileo, GLONASS, QZSS, SBAS signal to
provide 3D navigation in a single compact SMD module. The
PX1100S can track all in-view GPS, Beidou, Galileo,
GLONASS, QZSS satellites. It is fully autonomous such that
once power is applied, the receiver automatically searches,
acquires and tracks satellite signals. When a sufficient
number of satellites are tracked with valid measurements,
the receiver produces 3D position and velocity outputs.
Global quad-constellation signal receiving capability enables
using greater number of satellite signal than GPS/GLONASS
dual-constellation receivers. The increased satellite number
offers superior performance in challenging urban canyon
and multipath environments.
Single-chip Phoenix positioning engine is inside the receiver
module. It features high sensitivity and fast TTFF. The
PX1100S can acquire, track, and get position fix
autonomously in difficult weak signal environment. Its high
tracking sensitivity allows continuous position coverage in
nearly all outdoor application environments. The high
performance signal parameter search engine is capable of
testing 16 million time-frequency hypotheses per second,
offering superior signal acquisition and TTFF speed.
