Abstract
A method and system of synchronizing multiple tracking devices in a geo-location receiver system comprising: receiving a first plurality of geo-location signals with a first tracking device; and receiving a second plurality of geo-location signals with a second tracking device. The method also includes: enabling the first tracking device as either a master tracking device or a master-with-mark tracking device; enabling the second tracking device to operate as a slave tracking device; the master tracking device generates and transmits a timing signal to the slave tracking device; and the master-with-mark tracking device is configured to receive an external input for synchronization and generates and transmits a timing signal to the slave tracking device. The method also includes acquiring the first plurality of geo-location signals and the second plurality of geo-location signals at a substantially simultaneous instant of time.
