This GPS Receiver Modem is based on SIMCOM’s SIM28M/SIM28ML GPS Module. SIM28M is a stand-alone or A-GPS receiver. With built in LNA, SIM28M can relax antenna requirement and don’t need for external LNA. SIM28M can track as low as -165dBm signal even without network assistance. SIM28M has excellent low power consumption characteristics (acquisition 17mA, tracking 16mA). SIM28M supports various location and navigation applications, including autonomous GPS, QZSS, SBAS ranging (WASS, EGNOS, GAGAN, MSAS), DGPS and A-GPS.
The antenna circuitry built in this modem is capable of receiving signals even at difficult locations where other modem fails to receive signal. Use an external antenna of 1575.42MHz.
