iPhone 4S Equipped GLONASS Navigation

addition of course equipped with a GPS feature, in fact, the iPhone 4S also features the ability to capture signals GLONASS (Global Navigation Satellite System). Although never a serious rival during the cold war era, in fact Apple products like iPhone and iPad quite popular in the Russian market. GLONASS itself was built in the era of the Soviet Union in 1982, but since the collapse of the Soviet Union in 1991, the program stops and the new GLONASS dihudupkan back to the era of Russia's economic revival in early 2000.

Like the smartphone OS market, segment navigation technology for the next competition will likely taper. GPS made ​​by the U.S. in the future have to face the 'invasion' GLONASS and the European Union recently has also launched the Galileo satellite navigation. Menyikap map competition, Qualcomm and ST-Ericsson's smart enough to offer a smartphone chipset that can support the functions of GPS and GLONASS simultaneously.

For information, the GPS until now have slightly better accuracy compared with GLONASS, but for the northern hemisphere GLONASS provides a better mapping. When both are combined, the accuracy will increase significantly and the determination of the location to be faster because there are 55 satellite involved, 31 belong to the GPS satellites and 24 GLONASS satellites belong.
