There are many possible issues that could cause the location of your GPS unit to be inaccurate.
GPS:
“a navigational system using satellite signals to fix the location of a radio receiver on or above the earth's surface”
GPS works by triangulating the device with the location information from the satellite network. While this technology is certainly advanced it is not perfect. Let’s cover some of the common issues with a Trackunit GPS device.
GPS Drift: As stated before GPS is not 100% accurate. Sometimes you can have a drift of the “location” of the unit due to a variety of factors from weather to hardware performance of the unit. This can sometimes be misread as “Activity” when the drift consists of several units of measurement.
Weak GPS Signal: Damage to the Trackunit device can interfere with the device communication ability. This can be checked by looking at the LED light on the Trackunit device.
Physical obstruction of the device: Physical interference to the satellite above can occur in many ways. Please ensure the device has access to clear sky (and satellites) above. This can be checked by looking at the LED light on the Trackunit device.
Signs that you do not have a solid GPS Signal
New Manager
One of the key indicators of the lack of GPS signal is the unknown status of the Trackunit. This means the Trackunit has not checked in for a length of time.
Manager Classic
You can view the status of the Trackunit and see the strength of the GPS signal for the unit. In this example you can see this unit does not have any GPS signal.
Verify
Verify displays the status of the GPS signal and give us information on the last GPS fix.
Using the same unit we can see the that this unit has not reported for several days, and has a signal strength of 0.
