The GNSS enabled sports watches are devices initially targeted for athletes. Nowadays, it has become very important for runners or cyclists to precisely monitor their activities in terms of training features, such as track speed or distance, but also for health monitoring indications, like heart rate. These health monitoring competences targeted the market of this product not only for athletes, but also to a broad spectrum of users, such as persons who need a physical training program to recover from surgery or disease [1].
Product Description
A GNSS enabled watch is a simple device and in its essence is a stop watch combined with a handheld unit. Basically these GNSS-based speed and distance systems are composed of two components, a GPS receiver and a watch [1].
Currently more complex products have features such as heart rate monitor, odometer, pace calculation or performance indicators.
However, the GPS watches do not provide location information, because they are marketed as awareness equipments for speed and distance solely.
Usually the watch user interface is very simple and some models own a touch screen allowing a easy use of the device.
These devices owns a USB interface to connect with a computer, in order to recharge the watch, but also to download the collected data onto proper applications which manage the monitored logs. Once the information is downloaded it's possible to access readings for heart rate, distance, current pace, average lap pace, average run pace, among others, providing an integrated training and monitoring platform.
Some models offer the possibility of integrate the collected information with tools like Google Earth in order to let the user observe the routes accomplished afterwords.
These products are considered as non-critical products.
The accuracy required by these applications is low. The current accuracy provided by civilian GPS is enough for these applications. Availability, however, can be reduced by heavy foliage and deep canyons in this type of environment.
Product Characterization
The GNSS receiver can be worn on the arm or clipped to a belt and resembles a typical digital watch.
Some of the features available in specific models are the possibility of competing with the recorded best results or even against other runners through means of downloading data from other users into the watch.
Product Examples
There are currently at least four manufacturers of GPS watches:
- Garmin watches products Garmin currently owns a line of eight different GPS watches.
- [ Timex ]
- [ Polar ]
- [ Bushnell]
- [ Suunto ]
Casio used to have one, but it's currently discontinued.
