Geode is not seeing satellites

13 Apr 2021

This article explains some of the common problems and solutions for when the Geode GNSS (GPS) receiver is not seeing satellites.

Using a New Receiver

To obtain the most accurate position, the new receiver must be turned on and left outside for at least 25 minutes.

When a new receiver is first used, it needs to receive and download the Almanac message from the GPS satellites. Each message from a satellite repeats every 12.5 minutes and until the download is complete, the receiver will either not see any satellites or see a very limited set of satellites.

For more information see the Geode Owner's Manual.

Factory Reset

If the receiver is reset to the factory defaults (a hard reset), moved a long distance from its previous location (across states or country), or has been in storage for a long time (months), a new Almanac will need to be fully downloaded to the receiver before it will see satellites.

To obtain the most accurate position, the receiver must be turned on and left outside for at least 25 minutes.

Enable NMEA Sentences

Specific NMEA sentences need to be enabled to view which satellites are visible by the receiver. In most instances, the default NMEA sentences are sufficient. The Geode Connect utility (or a terminal connection) can be used to enable these sentences. For more information about which specific NMEA sentences should be used with your device see the Geode Owner’s Manual.

To verify and enable the GNS, GSA, and GSV sentences that contain satellite information, as well as other NMEA sentences, select Receiver Configuration (Settings) > NMEA Sentences.

Specific Constellations

You can verify if a Geode unit is GPS only or Mulit-GNSS by entering the serial number on our Check Product Status web page. An upgrade code can be purchased if needed. If you cannot see satellites from a specific GNSS constellation (such as Galileo or Beidou), please see Geode not showing Galileo or Beidou satellites.
