Abstract
Disclosed is a method of calculating a geospatial position by a mobile device by monitoring with the mobile device a first control channel from a first cell of a cellular communications system; monitoring with the mobile device a second control channel from a second cell of the cellular communications system at the same time as the first cellular control channel; receiving with the mobile device a first correction value sent over the first control channel; receiving with the mobile device a second correction value sent over the second control channel; receiving with the mobile device a signal from a global navigation satellite system; calculating with the mobile device the geospatial position based upon the signal from the global navigation satellite system and at least one of the first correction value and the second correction value.
