Q2. Should I buy a GPS module or a GNSS module?
Choose a GNSS module unless cost is your only concern and 5–10 m accuracy is enough. A GPS-only module is fine for basic consumer navigation, but for drones, robots, precision agriculture, surveying or any obstructed environment, a multi-constellation GNSS module is the safer choice. Today the price gap between a GPS-only and a multi-constellation GNSS module is small, while the reliability gain is large.
