    9595The goal of this section is to provide a surface level understanding of the software components related beginning development on the [https://www.gateworks.com/products/mini-pcie-expansion-cards/gw16143-high-precision-gps-mini-pcie-card/ GW16143]. The primary component on the GW16143 is the [https://www.u-blox.com/en/product/zed-f9p-module U-Blox ZED-F9P] high precision gps module, and is overall comparable to the [https://www.u-blox.com/en/product/c099-f9p-application-board C099-F9P application board] in a mini-PCIe form factor. Notable differences between the C099-F9P and the GW16143 would be the absence of the ODIN-W2 (networking) module and the the addition of an antenna supervisor circuit.
