Invoke get current coordinates every few seconds without NSTimer

http://stackoverflow.com/questions/12841017/invoke-get-current-coordinates-every-few-seconds-without-nstimer

5.0 Change that 5.0 to the minimum time you want between stored locations. It won't be exact will vary on the rate of travel and the signal strength but basically after x seconds interval it will consider the stored location stale and attempt to.. do what you are looking to do while still respecting user battery and background operation. Basically when a user is traveling updates will be continuous at about the interval you have set. When a user is stationary there will be no updates and..

though and this is not very CPU or battery light. Using the IMU you get a fair idea of the distance direction of travel and if this is over a short period of time we assume the other 'side' is stationary. This helps a lot to get a value for..

iPhone fluid simulation

lattice gas automata . With lattice gas automata you approximate a fluid as a fine hexagonal grid where particles can travel in one of six directions and obey specific collision rules. There are some limitations to this approach addressed by the..

Corelocation framework does not produce accurate distances

http://stackoverflow.com/questions/3118773/corelocation-framework-does-not-produce-accurate-distances

framework does not produce accurate distances I am developing an application that computes the distance travelled by the person. I am testing it on a iPad Device 3.2 . My iPad is using WiFi to get the current location. The results.. @ oldd @ oldL NSLog @ new @ newL CLLocationDistance currentDistance oldL distanceFromLocation newL NSLog @ you have travel f currentDistance distance distance currentDistance double distanceInKm distance 1000 NSString distanceLabelValue NSString.. returned with each point. And look at the height. If they are inaccurate then the velocity and therefore distance traveled will be too. One cause of bad distances is if one end of your pair has an altitude and the other does not the not gets..

of your receiver relative to two but preferably more base stations. Even then this is still a hard problem. RF waves travel at the speed of light so using relay techniques to measure round trip signal propagation delay won't give good accuracy..
