HG-RFSIM4-M portable GNSS signal simulator is a GNSS RF signal simulator that can be completely independent of PC. It differs from HG-SIM2 in that its hardware is based on high-performance SOC technology, and it does not need external device computing power to work properly. HG-RFSIM4-M comes with a TF card, and most settings can be set via TF card, which is easy to use. HG-RFSIM4-M can set some parameters during running via RS485 interface. Simple serial debug assistant, Raspberry Pi, or a simple STM32 processor can realize normal operation of the simulator.
