What had to be solved
The task was to make a service device for autonomous GPS trackers. A tracker is inserted into a charging cell, and the electronics determine its presence and whether charging is needed.

Engineering context
Important constraints
The device worked with autonomous GPS trackers that include a modem.
It had to detect whether a tracker is present in a specific charging cell.
Charging should not require manual checking of every tracker state.
Charge completion is shown with green light indication.
Work done

Engineering project description
Device purpose
The project belongs to the service infrastructure for autonomous GPS trackers. Such devices are useful when trackers are regularly removed from an object, charged and then returned to operation.
Operating logic
The key logic consists of three steps: detect tracker presence in the cell, determine whether charging is required and show charge completion with a green indicator.
Practical value
A multi-cell charging station makes repeated tracker service more organized: the operator does not have to treat each tracker as a separate loose device and manually infer its charge state.
