The positon config options are: GPS Enabled, GPS Update Interval, GPS Attempt Time, Fixed Postion, Smart Broadcast, Broadcast Interval and Position Packet Flags. Position config uses an admin message sending a `Config.Position` protobuf.
Position data from GPS is provided by either the radio or your paired phone. Position data is not required to use Meshtastic but time calculations require at least one device on the mesh have either a gps or internet connection for time.
How often should we try to get GPS position (in seconds), or zero for the default of once every 30 seconds, or a very large value (maxint) to update only once at boot.
### GPS Attempt Time
How long should we try to get our position during each GPS update interval attempt? (in seconds) Or if zero, use the default of 30 seconds.
### Fixed Position
Acceptable values: `true` or `false`
Off by default
If set, this node is at a fixed position. The device will generate GPS updates at the regular GPS update interval, but use whatever the last lat/lon/alt it saved for the node. The lat/lon/alt can be set by an internal GPS or with the help of the mobile device's GPS.
### Smart Broadcast
Acceptable values: `true` or `false`
On by default
Smart broadcast will send out your position at an increased frequency only if your location has changed enough for a position update to be useful.
Smart broadcast complements broadcast interval (doesn't override that setting) but will apply an algorithm to more frequently update your mesh network if you are in motion and then throttle it down when you are standing still. If you use this feature, it's best to leave broadcast interval at the default.
Smart broadcast will calculate an ideal position update interval based on the data rate of your selected channel configuration.
### Broadcast Interval
Default of `0` is 15 minutes
If smart broadcast is of we should send our position this often (but only if it has changed significantly)
The GPS updates will be sent out every Broadcast Interval, with either the actual GPS location, or an empty location if no GPS fix was achieved. This defaults to broadcast every 15 minutes.
### Position Flags
Bit field of boolean configuration options for POSITION messages (bitwise OR of PositionFlags)
The device will continue to acquire GPS coordinates according to the `gps_update_interval`, but will use the last saved coordinates as its fixed point.
:::
```shell title="Set Fixed Position - User Defined"
It may take some time to see that the change has taken effect. The GPS location is updated according to the value specified on `gps_update_interval` and the mesh will be notified of the new position in relation to the `position_broadcast_secs` value.

Include each flag desired separated by a single space.
Altering/disabling the GPS functionality does not mean that you will be unable to be found. Via triangulation of your radio, location may be given up to someone if they are determined enough.
