L1 Quad Constellation
GNSS Receiver Module
The PX1120S 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
PX1120S 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. PX1120S
can acquire, track, and get position fix autonomously in
difficult weak signal environment. Its high 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.
The receiver module contains SAW filter and a notch filter
to remove out-band interference and LTE B13 signal at the
RF input prior to the first stage LNA. This configuration
allows normal operation even under strong RF interference
when cellular modem is near the PX1120S.
PX1120S is backward pin-to-pin compatible with earlier
SkyTraq 12mm x 16mm form factor GNSS module, allowing
very easy migration.
