Build a GPS Speedometer and Tracker

I need to produce a GPS Speedometer and Tracker waterproof and low temperature resistant Please find attached technical project design. The data from the GPS satelites is analysed and displayed by the product module. This allows you the check data about your position, your speed, altitude and other info relevant for your security in your field of view. At the same time all GPS data can be stored on the integrated microSD card for later evaluation. The computer software on the included microSD card allows you to transfer your tour data to your computer for analysation and visualisation of your tour. Additionally you can view your tour in Google Earth™, generate speed and altitude profiles and import your digital photos. The Speedometer + Tracker shows the following functions in the display: · Actual Speed · Maximum Speed, over all runs · Maximum Speed, last run · Actual altitude · Maximum altitude · Distance downhill The display switches automatically all 3 seconds between the different functions as long as the actual speed is less than 20 km/h or 12 M/h. Over 20 km/h or 12 M/h the display shows only actual speed All informations stored in the Tracker should be available on appropriate app
