Overview chipset ic

I evaluated the real-world Csrg0530 accuracy of GPS watches while running over 12,000 miles/19,000Km and recording over 50,000 data points as part of my evaluation of the Best Running Watches. Under good conditions most of the watches are remarkably good, but when things get a little tough the differences become more apparent. However, none of the watches have GPS accuracy that is good enough to be used for displaying your current pace.

As a result, Csrg0530 I’ve added the test results for various Footpods as they can be far more accurate than GPS, but more importantly they tend to have far less moment-to-moment variation so they can give a far better display of your current pace. (Note that my accuracy tests focus on the ability to measure distance, not the moment in time position, though the two are obviously related.)

The values used are simply 10 minus the value for trueness (average) and precision (standard deviation from true). Csrg0530 The overall is the combination of trueness and precision. Repeatability is how consistent a watch is in providing the same value for the same course segment.

Important: Manufacturers do not typically release the type of GPS chipset used, so the information in this table is based the best available data, but it should be treated with caution.

We can look at trueness by measuring the average lap length and precision by measuring the standard deviation. I use the traditional approach to standard deviation (variation from mean) as well as a modified approach that uses variation from the true value. (It is more common in many fields to use “accuracy” to mean closeness to true value and “validity” to mean the combination of accuracy and precision.

However, I feel that the meanings used by ISO 5725 are closer to the common usage. If a company sold ‘accurate’ 12 inch pipes and shipped half of them as 6 inches and half as 18 inches, they would meet the traditional definition of accuracy, but few people would be happy with the product. )

In addition, Csrg0530 I calculate a value for “repeatability”, which is a measure of how likely a watch is to give the same distance measurement for a specific course. I calculate the standard deviation for each segment of the course, and then take the average. A high repeatability score can mask poor accuracy and can convince users they have a good device.

The table below shows summary data for each device. Csrg0530 The count field is how many measurements I have for that combination of condition and device, with each measurement being a quarter mile distance. I generally aim for over 1,000 data points to even out the effects of weather, satellite position and other factors. The Trueness is the absolute of the mean, though nearly all watches tend to read short.

The standard deviation is provided based on the variance from the mean and the variance from the known true value. The average pace error is shown to give a sense of how much error you’re likely to see in the display of current pace. This is an average error not a worst case. The data shown below is a summary the accuracy based on all the sections. If you’d like more detailed information, I’ve split off the Detailed Statistics for GPS Running Watches for the results under different conditions.

I expected GPS watches to improve with time, Csrg0530 but the opposite appears to be happening. With the Garmin devices especially, you can see that the older watches generally do far better than the newer ones. I suspect this is due to compromises to get better battery life and smaller packaging and the cost of GPS accuracy.

While the specific chipset used in a GPS watch will impact its accuracy, there are many other factors that come into play. The physical packaging of the chipset, the antenna used, the particular features that are implemented, and the software that interprets the raw data will influence the overall accuracy.

It’s important Csrg0530 to note that the SiRF chipsets such as “SIRFstarIV” are not a single chipset, but rather an overall architecture with several specific chipsets bearing the same name.
While it’s tempting to take the various GPS watches on a single run and simply compare the totals, this is a flawed approach. Evaluating the devices GPS accuracy on the basis of a single sample does not tell you much. It’s a bit like evaluating an athlete’s ability on the basis of one event; everyone has good days and bad days, and that applies to GPS watches as well.

To illustrate this, the images below are from two runs, recorded on 9/20 and 9/22. In each run I recorded data on both the 310 and 910 watches, hitting the lap button on both at as close to the same time as is humanly possible. Csrg0530 On 9/20 the 910XT was far more accurate than the 310XT, but on 9/22 the situation is reversed.

If you were to have evaluated the two watches on the basis of a single run, you would conclude that one is much better than the other. But which device would win would depend on the particular day. This is why I’ve accumulated a lot of data to do a statistical analysis to work out which is really better.
