Some mobile phones have built in global navigation satellite system (GNSS) for finding your position and magnetometer (Compass) for finding your orientation.
Mobile phone built-in magetometer can be used as a compass.
- Move away from metal
- Make "figure 8s" in the air with your phone

3. In Depth
Mobile phone built-in GNSS capability is a major contributor to geopos.org's location feature. We are pushing it to its limits to get higher accuracy in shorter time.
Need at least 4 satellites to give you latitude, longitude, altitude and time.
- Get unobstructed view of sky
- Get as many satellites a possible
For high precision get a phone with Dual Frequency GNSS support (e.g. high end Samsung and Huawei phones).
In order to get accuracy down to centimetre level, Real Time Kinematic (RTK) or Post Processing Kinematic (PPK) can be used with your mobile phone.
Our geopos.org application encourages citizens to build up their own RTK infrastructure in the communities.
