Start with the real-world problem.

GPS receives positioning signals. Sending that position to an app requires a separate connection, such as cellular, LoRaWAN or satellite, depending on the device.

Cellular service depends on local coverage. Offshore use may require satellite communication; GPS alone cannot send a location ashore.

Reporting interval, signal strength, temperature and battery capacity all matter. Ask for measurements under your actual usage conditions.

Prepare your target market, connectivity, enclosure, quantity and integration requirements. Feasibility, minimum order and certification need project-specific confirmation.
