CPE


 

 

What is CPE on an Outdoor Product?

• Connected Predictive Ephemeris (CPE) files allow GPS receivers to predict where satellites will be in the sky, significantly reducing signal acquisition time.
• Without current CPE information loaded, the GPSr can require several minutes to locate available GNSS signals.
• With current CPE information loaded, the GPSr will usually find available GNSS signals within just a few seconds.
• Tip: The CPE file provides global constellation coverage and does not need to be updated after changing location.
   

How do I check CPE Status?

• CPE status can be checked in the 'System > About' or 'Setup > About' page on many Garmin outdoor products.
• You can also manually check the 'Date modified' status for the [GPSr]\Garmin\GPS\CPE.BIN file on your device.
• CPE files do expire, and are usually only good for a range of 3-14 days.
• Sync the device regularly to keep CPE data current.
   

How is CPE Data Downloaded?

• Satellite location information is refreshed periodically when your GPSr syncs data with your smart phone.
• This data is also refreshed if the device has not been used in over 30 days, or when it has traveled more than 200 miles from its last satellite connection.
• Frequently syncing your GPSr via the Garmin Connect or Explore mobile apps, Garmin Express, or by connecting to an active Wi-Fi network will ensure the most current satellite location information is always available.
