- The perfect solution for measuring speed and distance across land, snow, and water
- Record positioning data and view your route on a map afterwards
- More accurate GPS positioning and longer battery lifetime than before
GPS stands for Global Positioning System. Polar G5, G3 and G1 GPS sensors are GPS receivers and they use the GPS (Navstar) system which enables the calculation of an accurate position anywhere on earth based on the special GPS satellite signals. The system is built and managed by U.S. Department of Defence and has free global use. The GPS receiver, like Polar G5, G3 and G1 sensor, calculates its position by measuring the distance between itself and four or more GPS satellites. This enables accurate position measurement of the GPS receiver, and the speed and distance calculation from the different positions of the receiver.
- Sensor can be worn in the rain, or when swimming, crossing rivers, canoeing, etc. The GPS reception or signal transmission from the sensor to the training computer will not, however, work in water. To maintain water resistance, make sure the G3 GPS sensor battery cover is firmly tightened. Do not press any buttons under water.
- Polar G3/G5 GPS sensor W.I.N.D. and Polar G1 GPS sensor need signals from four different satellites to establish the starting position. In the right conditions signals are found within 30 - 60s, sometimes even faster if you have started the G3/G5 or G1 GPS sensor at the same position previously.
- Polar G3/G5 GPS sensor measures speed, distance and tracking data. When using G3/G5 with Polar RCX5 / RS800CX / CS600X speed, distance and tracking data is recorded. But when using G3 with Polar RS800 only speed and distance data is recorded. RS800CX and CS600X training computers have additionally an altitude measurement feature to allow you to track the exercise elevation profile and to analyse the results in Polar ProTrainer 5 software.
