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.
   

Manual CPE Download + Installation

• Should your Garmin GPSr exhibit trouble updating CPE data, follow these steps to manually obtain and install a current CPE.BIN file:


• GPSMAP 67, 67i (Airoha / MediaTek GNSS Chipset)


• Open Windows Terminal (press Win + R, type wt, press enter) and copy / paste the following command:
• curl -o CPE.BIN "https://api.gcs.garmin.com/ephemeris/cpe/rxnetworks/bytes?coverage=DAYS_7"
• Copy CPE.BIN from [C:]\Users\{User Name}\ to the [GPSr]\Garmin\RemoteSW\ directory on your Garmin Outdoor device.
  
  
• GPSMAP 65, 65s, 66sr (Broadcom GNSS Chipset)


• Option 1:
• Open Windows Terminal (press Win + R, type wt, press enter) and copy / paste the following command:
• curl -o CPE.BIN "https://api.gcs.garmin.com/ephemeris/cpe/broadcom?coverage=WEEKS_1"
• Copy CPE.BIN from [C:]\Users\{User Name}\ to the [GPSr]\Garmin\GPS\ directory on your Garmin Outdoor device.
  
  
• Option 2:
• Download and unzip CPEupdate.
• Windows users run getCPE.cmd, Linux/Unix users run getCPE.sh.
• A new CPE.BIN file will appear in the same directory (you may have to refresh the directory).
• Copy this file to the [GPSr]\Garmin\GPS\ directory on your Garmin Outdoor device.
• Tip: Copy the \CPEupdate\ folder to your Garmin GPSr and run the updater while connected to any computer with an active internet connection (CPE.BIN will automatically be placed in correct directory).
  
  
• Sony GNSS Chipset 


• (GPS, GLONASS, Galileo, QZSS):
• Open Windows Terminal (press Win + R, type wt, press enter) and copy / paste the following command:
• curl -o CPE.BIN "https://api.gcs.garmin.com/ephemeris/cpe/sony/lle?coverage=WEEKS_1&constellations=GPS,GLONASS,GALILEO,QZSS"
• Copy CPE.BIN from [C:]\Users\{User Name}\ to the [GPSr]\Garmin\GPS\ directory on your Garmin Outdoor device.
  
  
• (GPS, GLONASS, Galileo, BeiDou, QZSS):
• Open Windows Terminal (press Win + R, type wt, press enter) and copy / paste the following command:
• curl -o CPE.BIN "https://api.gcs.garmin.com/ephemeris/cpe/sony/lle?coverage=WEEKS_1&constellations=GPS,GLONASS,GALILEO,BEIDOU,QZSS"
• Copy CPE.BIN from [C:]\Users\{User Name}\ to the [GPSr]\Garmin\GPS\ directory on your Garmin Outdoor device.
  
  
• Restart the GPSr and verify CPE status is 'Current'.
