A base station device includes a network interface including a global navigation satellite system (GNSS) receiver and an electronic processor. The electronic processor may be coupled to the network interface. The electronic processor may be configured to receive, via the GNSS receiver, a first location signal from each of a first plurality of satellites while the base station device is located at a first location. The electronic processor may also be configured to determine a first signal strength of the base station device at the first location. The first location may be a first potential location of the base station device from which the base station device is configured to provide location calibration information based on communication with the first plurality of satellites to a robotic garden tool. An indication of the first signal strength may be output via an output device for consumption by a user.
