Equine Speedometers

Makarand writes "According to this article in The New Zealand Herald scientists at Massey University (NZ) are using GPS to monitor racehorses during their training programme. GPS technology is being used to follow horses around a racetrack and measure how far and fast horses gallop each day. This GPS data along with heart rate measurements is transforming racehorse training into a science."

Importance of GPS, & questions on its Reliabil

[dexterpexter]

A smally nitpick: As someone who worked in the equine industry before I entered the tech world, I personally believe that horse racing is a science (in a broad sense), and always has been. *smiles*

I believe several posters hit an important point when they stated that they have been able to measure a horse's speed for years using stopwatches. However, they should consider that this technology is only as useful as the person pressing the button, and relies on the user to be able to determine *exactly* when that horse's nose touches the line, and for them to be able to press the stop button fast enough. This tool is extremely handy because, assuming it has great accuracy, it takes the human error problem out. You might not think that parts of a second would matter in horse racing, but it does. Fractions of a second came between breaking Secretariats (famous race horse) track record, and not. It is true that they have bream beams at the major tracks, but overall photo technology is used to determine split seconds, who won, etc., and often this is not available to trainers outside of a race. GPS will simplify that process.

However, my concern is that, having used this technology in a robot that we are working on, the readings are sometimes unreliable as one second it may say you are one place, and the next tell you that you are a foot the other way. That might not seem like a huge distance to you, but combine that with the 30+ mph galloping speed of a well-trained thoroughbred, and you have a problem when it reads the horse as finishing when it really has not. I would be interested in seeing how they address this problem. In horse racing, when gauging against track records, split seconds count!

I believe that a greater application of this technology would be to track those expensive animals in the case that they get stolen. They have been using a variant of RFID to do this for years, but it is limited in distance and thus rarely actually catches animals except at slaughterhouses where they are required to scan for a stolen animal. This might ease an insurance company's mind, and also the owner's, knowing that their animal can be tracked in-transit. Awesome.
