Many factors can affect GPS accuracy on mobile devices, including:
- The GPS chipset of the device
- Signal obstruction by buildings, trees, and other structures
- Availability of cellular and data networks
Some best practices for improving the accuracy of your reported GPS location include:
- Positioning your device so that its GPS antenna can receive a strong signal (see your device manual)
- Standing where you have a clear line of sight to the sky
- Reducing signal interference by moving your GPS device away from other GPS and electronic devices
- Ensuring that a mobile device like a smartphone has access to mobile data
- Making sure the SafetyLine app has access to location services
- Double checking all features related to GPS are turned on within the SafetyLine app
In situations where GPS availability is limited, it is especially important for Workers to leave detailed check-in messages that contain their current location as well as destinations and estimated arrival times if they are travelling.
