Upgrading the GPS Module firmware of A2 flight controller
After communicating with existing A2 users, we find that there are many users do not update the GPS Module to the latest firmware when upgrading the A2 firmware v2.1.

The A2 firmware includes two part, firmware for GPS Pro and firmware for GPS Module. The GPS PRO module communicates with other modules and the GPS Module tracks location.

This new firmware for GPS Module optimizes the algorithm of calculating GPS positioning information and improves the performance of the GPS when flying in bad weather. It will also help to prevent cases such as lost GPS signal that is often caused by numerous environmental factors. This new firmware will greatly improve the performance and safety of the A2 system.

DJI suggests that all A2 users should get their systems updated, especially the GPS Module to the latest firmware.

Please watch the A2 firmware upgrade tutorial video below.
