Diagnostic Screens
DriftBox has two different diagnostic screens, use ▲▼ to swap between the two.
GPS Diagnostic Screen
This screen allows you to view the following basic GPS information:
 Number of satellites being used by
DriftBox.
 Signal strength of each satellite.
 Satellite time (UTC)
 Latitude.
 Longitude.
 Height (with respect to sea-level at
Greenwich).
Note: In this screen data is logged to the SD card at 1Hz not 10Hz
Yaw-rate Sensor Diagnostic Screen
This screen displays the following information relating to the internal YAW sensor
 YAW rate in degrees per second.
 Angle (calculated from Yaw Rate)
 Temperature of the YAW rate sensor
Cold Start
A cold start completely re-initialises the DriftBox‟s GPS engine. GPS coldstarts clear the GPS
engine‟s list of satellite positions and configures the GPS engine for normal DriftBox operation. For
this reason, coldstarts should be performed at the following times:
 If DriftBox has not been used for more than three weeks.
 If DriftBox has moved over very large distances (thousands of miles) whilst turned off.
 If DriftBox‟s firmware has just been upgraded.
Because each of these are common during distribution, it is also recommended that the DriftBox is
coldstarted on its first use. After performing a Cold Start the vehicle to which DriftBox is connected
should be left in an open area for at least 15 minutes, to re-acquire the satellite almanac. You
should only need to do a cold start when you first receive your DriftBox, or you are experiencing
poor satellite reception in an open area.
