GW16143 High-Precision GNSS/GPS Mini-PCIe Card
Overview
The GW16143 is a high-precision GPS Mini-PCIe card designed to provide precise positioning to applications utilizing Gateworks single board computers.
It provides centimeter-level (<2cm) accuracy (see Note 1) via GNSS positioning with concurrent reception of GPS, GLONASS, Galileo and BeiDou. A MMCX antenna port allows for an external antenna. USB signaling is used on the Mini-PCIe connector to communicate with the host processor. Two UART headers are available for correction data via serial. A time pulse output header provides PPS signaling. To take advantage of faster acquisition times, a rechargeable 3.3V lithium battery is included. For mobile applications, it provides a high update rate. Multi-band Real-time kinematic (RTK) technology provides fast convergence times and reliable performance. The module supports both base and rover operations for RTK applications.
Differential GNSS devices such as the GW16143 are starting to replace survey-grade equipment. Other radio cards such as the Gateworks GW16130 Iridium Satellite Modem or GW16132 CAT-M1 modem can provide communication links for the augmentation data. The GW16143 enables precision navigation and automation of moving machinery in industrial applications such as agriculture, mining, and field mapping.
