High Performance GPS Data Acquisition

The MQGPS-TraQr is a breakthrough in capability, price, and ease of use compared to older accelerometer-based systems.  No worries about leveling the unit, no errors due to roads that aren't perfectly flat.  Stick it to under your windshield and go test.  Easily transfer the system to another car for comparison, then download your data to a laptop for analysis.

Just how accurate is it?  Validation testing consistently shows timings within a few hundredths of a second of dedicated track timing systems:

(MPH readings are slightly higher than trap speeds because they are calculated at the line, not as an average over the previous 66 feet)

The MQGPS-TraQr can also be connected to a laptop or Windows Mobile Pocket PC via Bluetooth for real-time data readouts and lap times using the MaxQData software.  It also works with third-party mapping and navigation software that can handle update rates greater than 1 Hz.
