GPS for iPad
The unique case design allows you to operate your device while it remains protected from the elements, including the touch screen, hard buttons, and audio headphone jack access. The integrated dock connector unites your iPhone or iPod touch with the ToughCase for power, audio, and GPS.
The ToughCase comes with a powerful and highly sensitive SiRFstarIIII GPS chip set. This enhances the accuracy of any location based and navigation app. This also improves the GPS accuracy of your iPhone to 10-15 feet and adds GPS functionality to your iPod touch. The integrated GPS chip set leverages SBAS systems, such as WAAS, EGNOS, and MSAS to improve accuracy in North America, Europe, and parts of Asia.
I have the iNavX marine navigation app on my Apple iTouch. We all know that the iTouch does not have a internal GPS but with GPS Gate I can use the WiFi network connection of the iTouch to connect to the GPS on my laptop. When I am out sailing I always have my laptop navigation programs running.
With GPS Gate running on my laptop simply select Settings and select the Output tab. Scroll down till you find TCP/IP server and select it. Set up the default port 20175 and under the Network button add your laptops IP address.
Start iNavX on your iPhone, iTouch or iPad and go to the Preferences, select TCP/IP NMEA Client. In the Host setting enter the IP address of the laptop running GPS Gate. In the Port selection enter the default 20175 or the port number you entered in GPS Gate. Next hit Link On and iNavX should be receiving GPS and other NMEA data from your laptop.
What I like about this setup is that you don't have to have any GPS physically connected to your iPhone, iPad or iTouch. Your are free to move around your boat keeping an eye on your position at all times.
