More than a decade ago, the Garmin eTrex was introduced and quickly became the benchmark by which other outdoor GPS navigators were measured. Its size, features and value made it a go-to unit for outdoor enthusiasts around the globe. Today, Garmin has chosen the eTrex line to debut a new state-of-the-art feature. The new eTrex 10, 20, and 30 are setting a new standard as consumer-grade receivers that can track both GPS and GLONASS satellites simultaneously. GLONASS is a system developed by the Russian Federation that will be fully operational by 2012.
When using GLONASS satellites and GPS, the time it takes for the receiver to “lock on” to a position is (on average) approximately 20 percent faster than using GPS alone. Furthermore, when using both GPS and GLONASS, the receiver has the ability to lock on to 24 more satellites than using GPS alone. This is particularly helpful for users who need reliable satellite navigation in challenging environments such as deep canyons or urban environments where a large portion of the sky is blocked by solid objects. The disadvantage to using both systems simultaneously is a reduction in battery life. Garmin is committed to providing its customers worldwide with the best available technology in its devices, and we intend to continue introducing new GLONASS-compatible receivers in the future.
