Virtually every cellphone tracks its movements. #Gps tracks plusIn 2020 tracking is a $2 billion business plus military-in the gulf war 10% or more targets used trackers. GPS antenna size limits tracker size, often smaller than a half-dollar (diameter 30.61 mm). Locations are stored in the tracking unit or transmitted to an Internet-connected device using the cellular network ( GSM/ GPRS/ CDMA/ LTE or SMS), radio, or satellite modem embedded in the unit or WiFi work worldwide. ![]() Satellite tracking devices send special satellite signals that are processed by a receiver.
