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.

Page 4: Pinout Description
In the idle condition, this pin should be driven HIGH. If the driving circuitry is powered independently of PX1100S, ensure that this pin is not driven to HIGH when primary power to PX1100S is removed, or a 10K-ohm series resistor can be added to minimize leakage current from application to the powered off module. - Page 5 Output voltage RF section VCC_RF No connection, empty pin Not used.

Page 7: Application Circuit
APPLICATION CIRCUIT When PX1100S has previously been used within 2 hour, for faster time to first fix powering up without needing to decoded ephemeris data from signal, V_BCKP should be connected to non-volatile supply; above figure with V_BCKP connected to rechargeable battery is an example implementation. If cold starting every time powering up is not an issue, V_BCKP can be connect to VCC. -

HANDLING GUIDELINE The PX1100S modules are rated MSL4, must be used for SMT reflow mounting within 72 hours after taken out from the vacuumed ESD-protective moisture barrier bag in factory condition < 30degC / 60% RH. If this floor life time is exceeded, or if the received ESD-protective moisture barrier bag is not in vacuumed state, then the device need to be pre-baked before SMT reflow process. - Page 12 “*” Checksum delimiter.
