All GPS receivers need a clear path to the satellites.
Most of the time the signal can't go through things you can't see through; your vehicle's roof, trees, buildings. In a vehicle, the best place for the GPS will be under the front window where the GPS will get a clear view of the sky above.
Avoid Buildings and other large solid objects.
These can not only block the signals, but can give you reflected signals, which will degrade the accuracy of the data.
Avoid titanium & steel objects.
These can interfere with the signal, so if possible try staying away from those objects.
Keep your battery charged.
Not only does this give your GPS better performance it will also help keep a better signal.
Don't use a case or pouch for your phone.
Some pouches may reduce the GPS signal quality, especially if it has a magnetic clip.
Set up your GPS before you start moving.
Since a plane moves reasonably fast, it can be hard for your GPS to locate an initial signal lock. Try setting up your GPS before you start moving. Being in a still position will ensure that a better signal is located.
Are you running the latest hardware?
GPS / phone hardware goes out of date fairly quickly. Newer GPS chipsets tend to achieve lock faster, and achieve a more accurate signal.
Know where your phone's GPS receiver is located.
Find where your GPS antenna is located on your phone. Sometimes it'll be on the same side as the screen, but on an iPhone it is on the back. So having the screen pointing downwards may work best for an iPhone.
Is your phone's GPS good enough?
Some phones will allow you to connect external Bluetooth GPS units to them. If you're running an iPhone, roqyBluetooth ( roqy-bluetooth.net/wp/
) may help you do this. Some external Bluetooth GPS's will allow an aerial as well, which will further improve your signal.
Obtain UFO/Alien technology.
Aliens are sure to have a better positioning systems than ours, so if you can get your hands on some and can work out how to use it, then that might be a great option. Don't annoy this guy
if you come across him though. He bites.
