Issue of GPS Accuracy 


Some GPs were found to be raising issue of low accuracy. It is informed that GPS should be locked at <10 meters only before capturing assets.


The smartphone communicates with satellites via a GPS antenna, which is part of the hardware in the majority of today's smartphones and tablets. This hardware is connected via a driver with the software. Thus, there are three sources of error for the GPS signal in the smartphone:


  1. The number of GPS satellites at the current location
  2. The quality of the GPS antenna in the smartphone
  3. The implementation of the driver in the operating system


Solution


Switch on 'High accuracy' mode


To get the best possible signal, one need to be prepared to use a bit more battery than normal. It's a necessary sacrifice, and you can always reverse it later when you don't need to use GPS. Enabling this is easy; just follow a couple of steps and you'll be on your way.


Go into android Settings and tap Location and ensure that location services are on. One should be able to toggle it at the top right hand of your screen. It should be green and the button to the right.


Now the first category under Location should be Mode, tap that and make sure it's set to High accuracy. This uses your GPS as well as your Wi-Fi and mobile networks to estimate your location. This will use more battery, but will utilize all available methods to give you the most accurate location possible.


Keep the GPS signal active


One of the main problems that we encountered when going from one app to another is that the GPS is turned off to save battery. If for example you are navigating and want to take a look at your latest messages, your GPS could be turned off. 


However, you can keep the GPS signal active. To do this you must install a GPS app. I recommend Connected GPS . It's a simple app and does the trick. Bear in mind that doing this could result in reduced battery life. Here is the link: https://play.google.com/store/apps/details?id=org.bruxo.gpsconnected


Find out if your GPS issues are hardware- or software-related


With GPS Essentials, a free android application, you can diagnose whether poor GPS signal is due to a hardware or software issue. In the GPS Essentials main menu, tap Satellites, then watch the phone connecting to satellites around the earth. Here is the software: https://play.google.com/store/apps/details?id=com.mictale.gpsessentials&hl=en


If no satellites appear, then this could be due to interference from metallic objects around, closed room, cloudy sky, the smartphone case, or your GPS hardware not working properly. If satellites do appear, but your GPS is still out of whack, then this is a software issue.


Refresh your GPS Data

Sometimes a device will get 'stuck' on certain GPS satellites, even if they’re not within range, causing it not to work properly. To fix this, you can use an app like GPS Status & Toolbox to clear your GPS data and to start connecting to satellites from scratch. here is the link: https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2&hl=en


In the app, tap anywhere on the screen, then tap the menu icon and hit Manage A-GPS state. Tap Reset, then when that's finished go back into the Manage A-GPS state menu and tap Download. Your GPS data should now be refreshed, and if it starts playing up again then just repeat this process.


If the above doesn't work, probably, one should try with another GPS Android Phone.
