This study tries to take advantage of this current (high rate) penetration of mobile and wearable devices such as smartphones as well as other GPS-embedded sensors to monitor, track, and record the geographical locations of moving objects (i.e., COVID-19 patients) in real-time. Furthermore...
The precise positioning service receivers always track the two codes like C/A code & P-code on both the signals with two frequencies like L1 & L2. At the receiver, the Y-code is decrypted to get P-code whereas, SPS receivers track simply coarse acquisition code on a signal with L1. ...
GPS fleet tracking refers to the use of a device carried in a vehicle or piece of equipment that uses the Global Positioning System to track its location remotely and in real-time. The equipment, using its associated software, can pinpoint the exact object location, often down to latitude an...
