Smablo

GPS

GPS satellites circle the Earth twice a day in a precise orbit. Each satellite transmits a unique signal and orbital parameters that allow GPS devices to
decode and compute the precise location of the satellite. Smablo GPS receivers use this information and trilateration to calculate a user's exact
location. Essentially, the Sablo GPS receiver measures the distance to each satellite by the amount of time it takes to receive a transmitted signal.
