    1515The following are similar navigation systems that do not have world-wide coverage:
    16  * China's BeiDou Navigation Satellite System
     16 * China's !BeiDou Navigation Satellite System
    1717 * India's GPS Aided GEO Augmented Navigation (GAGAN) and Indian Regional Navigation Satellite System (IRNSS)
    1818
     
    3535
    3636[=#beidou]
    37 == BeiDou Navigation Satellite System (China) ==
    38 The BeiDou Navigation Satellite System covers China and is planned to begin serving global customers upon its completion in 2020.
     37== !BeiDou Navigation Satellite System (China) ==
     38The !BeiDou Navigation Satellite System covers China and is planned to begin serving global customers upon its completion in 2020.

    8686== Hardware UART and Device Mappings ==
    8787The GPS devices used on Gateworks products communicate with the host processor over a serial UART:
     88 * Newport:
     89  * GW6304: /dev/ttyAMA1 [#zoem8q u-blox ZOE-M8Q] 9600bd NMEA 0183 output 1Hz
     90  * GW6404: /dev/ttyAMA1 [#zoem8q u-blox ZOE-M8Q] 9600bd NMEA 0183 output 1Hz
    8891 * Ventana:
    8992  * GW5100: /dev/ttymxc0 [#w2sg0008i Wi2Wi W2SG0008i] 4800bd NMEA 0183 output 1Hz
     
    110113  - [#gps GPS]: L1C/A (1575.42MHz)
    111114  - [#glonass GLONASS]: L1OF (1602MHz)
    112   - [#beidou BeiDou]: B1l
     115  - [#beidou !BeiDou]: B1l
    113116  - [#galileo Galileo]: E1B/C
    114117  - [#qzss QZSS]: L1C/A (1575.42MHz)
     
    122125  - PPS: 30ns RMS, 99% 60ns
    123126 * Sensitivity:
    124   - Tracking & Navigation: -167dBm (GPS&GLONASS) -166dBm (GPS) -166dBm (GLONASS) -160dBm (BeiDou) -159dBm (Galileo)
     127  - Tracking & Navigation: -167dBm (GPS&GLONASS) -166dBm (GPS) -166dBm (GLONASS) -160dBm (!BeiDou) -159dBm (Galileo)
    125128  - Re-acquisition: -159dBm
    126129  - Cold start: -147dBm
     
    156159 - Uses an internal TCXO (temperature compensated) oscillator to provide improved accuracy over the EVA-M8 which uses a crystal
    157160 - Smaller footprint (4.5mm x 4.5mm x 1.0mm) device vs (7mm x 7mm x 1.1mm)
    158  - Supports Galileo and BeiDou. EVA-8M only supports GPS GLONASS
     161 - Supports Galileo and !BeiDou. EVA-8M only supports GPS GLONASS
    159162 - Improved sensitivity (-167dBm vs -164dBm)
    160163 - Faster acquisition time (26s vs 33s)
