Frequently Ask Questions
The G2X is designed to provide trouble free performance. At times, problems could be encountered that
may affect data. We have attempted to provide answers for some of the most common questions and
problems.
Display dash is emitting a high pitch sound. Is something wrong?
No, the high pitch sound you hear coming from the Display Dash is the power supply and it is normal.
Does GPS always work?
The most often asked question, concerning the G2X. While GPS produces excellent data, no system is
perfect. If the data logger is unable to acquire at least three satellites, data will not be useable. There are
conditions that can affect signal reception.
1)
Driving through a tunnel or any location that will hide or shroud the GPS signals.
2)
Driving through an extensive row of trees or other natural or man made objects that might shroud
signal reception for an extensive period of time.
3)
Natural or man made obstructions, such as walls, signs, etc.
Will Rain Affect the GPS Signal?
We have not encountered an affect from rain, in our on track testing and usage. Again, there could be
some type of severe conditions that could affect the GPS signals.
Can I acquire elevation?
If the G2X has acquired 4 satellites, elevation is available.
Does the loss and gain of satellites affect the data?
No, as long as the GPS satellites remain at 3 or above, the DataLink software compensates for signal
change.
Speed accuracy?
In typical usage, the speed accuracy is approximately .50 MPH / .1 KMH. This number represents
the upper end of the accuracy statistic and would have no effect on data review. In reality, how
many drivers can detect a change of ½ mph, in high performance driving situations?
Laptime accuracy?
In multi-year testing of G2X vs. trackside beacon lap times, a maximum variance .05 has been noted.
GPS based lap times are dependant only upon vehicle location, and can not be affected by sunlight,
signal blockage from other vehicles, power loss to the transmitter, or other problems associated with
trackside transmitters.
