See Appendix C for more details. If you have received C94-M8P-E PCBvariants these units will have HPG1.40 on the M8P and the latest production radio modem firmware and will runmoving baseline mode at 1Hz using the C94 radio modems.UART baud rate of 38400 or lower is not supported for a wired serial connection (without C94 radio) at 4 Hz inmoving baseline mode.Navigation rate in moving baseline mode is dependent on the NEO-M8P processor load which includes UARTthroughput, amount of UBX messages enabled and amount of debug messages enabled. To achieve 4Hz (wiredserial connection only) with a high repeatability ensure that the minimum number of protocols and messagesare used.In moving baseline mode, the performance of the rover receiver can be significantly degraded if the latency ofthe communication link is too high or if the communication link is not reliable enough.
