1.5 GNSS
The NEO-M8P positioning modules are concurrent GNSS receivers that can receive and track multiple GNSS
systems. NEO-M8P receivers are configured by default for concurrent GPS and GLONASS reception. A
combination of GPS and BeiDou can also be used. If RTK update rate is a key factor, the receiver should be
configured to use only GPS.
1.5.1 GPS
The NEO-M8P positioning modules are designed to receive and track the L1C/A signals provided at
1575.42 MHz by the Global Positioning System (GPS).
1.5.2 BeiDou
The NEO-M8P modules can receive and process the B1I signals broadcast at 1561.098 MHz from the BeiDou
Navigation Satellite System. The ability to receive and track BeiDou signals in conjunction with GPS results in
higher coverage, improved reliability and better accuracy. Currently, BeiDou is not fully operational globally and
provides Chinese regional coverage only. Global coverage is scheduled for 2020.
1.5.3 GLONASS
The NEO-M8P positioning modules can receive and process GLONASS concurrently with GPS. The NEO-M8P
modules are designed to receive and track the L1OF signals GLONASS provides at 1602 MHz + k*562.5 kHz,
where k is the satellite’s frequency channel number (k =
–7,-6,..., 5, 6). The ability to receive and track GLONASS
L1OF satellite signals allows design of GLONASS receivers where required by regulations.
