Issue: Incomplete or Poor GPS/Positional data recorded for a session

Symptoms:

• GPS/Positional Data drops out for sections or periods of time throughout the Session
  
  
• GPS/Positional Data spikes to unreasonable/unrealistic values

Expected Behaviour:

• GPS data should be continuous/of consistent quality relative to the GPS environment the session was recorded in
  
  

Causes:

• Device was used in a Poor GPS environment, or entered a poor GPS environment for parts of the session
  
  
• Device turned off part way through the session
  
  
• Out-Dated GPS Firmware

Troubleshooting Steps: 

• Check if the Device was under cover or in an area that could block GPS signal for any amount of time?
  
  
• Consider if the environment is suitable for good GPS lock
  
  
• Check if the device was turned off at any stage during the session and turned back on:
  
  
  • You can check this by looking at how many raw files were downloaded off/recorded on the device. See this in the data transfer screen by selecting show all and viewing the dates, times and duration of recordings
    
    
    
    
• Test the GPS lock of the Device by recording a session on the device in a good GPS environment
  
  
• Check if the device was left to achieve GPS lock for 10-15 minutes prior to the session.
  See Preparing Devices for an Outdoor Session for more information.
  
  
  
• Compare Data to other Devices used in the same environment for the same session
