Design me a product with sample: GPS

We have selected Globalstar STX-3 chip for GPS satellite navigation. A suitable host processor and antenna Can you design a circuit design for the same (Gerber, Schematic) and provide a working sample. Main job is to set the interval of the tracking, power management etc The only purpose of the GPS tracker is to find its location for the GPS system. It will be placed on the shipping containers which will travel through ocean We must be able to track the location of the container at regular interval of time say 1 hour The time interval can be set through programming by connecting the circuit to a computer through USB Working: The circuit wakes up from sleep mode and connects with the satellite It sends the location to satellite and disconnects then it sleeps to conserve energy Th step 1 to 3 continues until the battery gets drained or we switch of a button on the circuit manually Dimension : 3 inch by 3 inch for PCB Preferably. Single sided PCB design Note : You can go for any other chip other than STX3. But it should have worldwide coverage and be cost effective Please send me the details of other chip you find before we continue. Ideal product will have the best coverage and cost efficient. Also make sure to use ISO certified components as much as possible. Scope: PCB design and a sample PCB (Power management, Tracking feature in land and ocean using satellite directly) Please contact me at +919747300019 if you have any queries.
