问题 Currently I am doing a GPS Tracking project based on Django and GREENTEL It uses this protocol http://www.m2msolution.eu/doc/Fejlesztoi_dokumentaciok/GT03/GPRS%20Communication%20Protocol_GT03.pdf It says how to convert Latitude/ Longitude to Hex.. but I want to convert latitude hex data to the normal form Conversion method: A Convert the latitude (degrees, minutes) data from GPS module into a new form which represents the value only in minutes; B Multiply the converted value by 30000, and

问题 guys i am able to get the current location longitude and Latitude using the below code. I have two buttons Start walking and Stop Walking. Onclick of Start Walking it will get the current location(longitude and Latitude) the person will start walking from A(source) position and walks from some time and comes back to A(now it becomes destination),after that he clicks on stop walking button. Now i need to show the user these details: 1.Distance that he walked in Kms. 2.Time he took in minutes.

问题 I have N GPS coordinates with N distances given to an unknown position which I wish to determine. My first approach was to use just three points and trilateration, exactly as described here. This approach was already quite accurate (best error~5km), but I would like to improve this and increase the robustness. Because the given distances are not very accurate to begin with, I thought about using multiple measurements and multilateration. However, it turned out that this approach is by far

问题 I create a proximity alert in this way private void setProximityAlert(float radius, double lat, double lng, String place) { long expiration = -1; LocationManager locManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); Intent intent = new Intent(TREASURE_PROXIMITY_ALERT); intent.putExtra("lat", lat); intent.putExtra("lng", lng); intent.putExtra("place", place); PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), -1, intent, 0); locManager

问题 Is it possible to receive GPS position with the maximal precision available on a mobile device from within the web browser? I've made tests on mobile devices using both getCurrentPosition() and watchPosition() from HTML5 Geolocation, walking around an office building. I've received on Android HTC Desire (Android Browser) and iPhone 3 (Safari) maximal precision of 70m, and no altitude/speed data, with WiFi turned on. After the WiFi was turned off, accuracy fell to 800-1000 meters. In the same

问题 Say you have a Windows Mobile 6.0 phone that also has a GPS receiver. Does the WinMobile SDK support accessing GPS functionality? If not, what are the options (API) for programming with the GPS i.e write apps that will use the GPS capability. I am mainly interested in Windows Mobile 6.x but please do include generic replies also. I will surely vote for the most helpful answers. Thanks in advance. 回答1: Two options: There is the intermediate GPS driver, which has a howto article for .Net on

问题 I am suffering from the problem of getting value 0.0 as latitude and longitude in Android Marshmallow (API 23) i.e. 6.0. I have searched a lot regarding this but didn't find solution of it. My code is fully working for the other API versions which are less than 23. I have also put the code for selfPermission and which all are working instead it's giving me 0.0 as late and long. Please have a look on the way I am following: GPSTracker.java public class GPSTracker extends Service implements
