The UBX-G7020-KT GPS Module with Enclosure is a ready-to-deploy GNSS receiver built around the u-blox UBX-G7020-KT chipset, combining a 56-channel satellite receiver with a purpose-built protective housing suitable for direct outdoor installation on RC vehicles, UAV frames, and embedded navigation platforms. The UBX-G7020-KT chipset delivers a tracking sensitivity of -161 dBm, placing it among the higher-sensitivity GPS receivers available in this form factor class, and supports SBAS correction for positioning accuracy below 2m in SBAS-covered regions, stepping down from the standard autonomous accuracy of 2.5m. The combination of a 1-second hot-start fix time and a 29-second cold-start Time to First Fix makes this module responsive in intermittently powered systems where rapid satellite re-acquisition after power cycling is operationally important.

The module communicates over a TTL serial interface at a default baud rate of 9600bps, with software-selectable rates from 4800bps through 921600bps to accommodate high-speed data pipelines in demanding embedded applications. Update rate is configurable from the default 1Hz up to 10Hz, supporting faster-sampling navigation applications such as FPV autopilots, ground vehicle tracking, and robotics odometry systems where 1Hz positional refresh is insufficient for accurate real-time path following. The protective enclosure measures 37 x 48 x 16mm and houses the 28 x 28 x 8.6mm module PCB with an onboard LED indicator for visual fix-status confirmation without requiring a serial terminal connection. A colour-coded 6-wire lead covering PPS, VCC, TXD, RXD, GND, and EN pins simplifies integration into breadboard, flight controller, and custom PCB builds without requiring pin identification from a datasheet during initial wiring.
