Let¡¯s compare GPS with the Russian GLONASS system. For GPS, the US has committed to maintaining at least 24 operational GPS satellites, 95% of the time. In the past few years, 31 satellites have been steadily operational. The GLONASS constellation was also completed in 1995, but at the end of the 1990s became incomplete with the loss of satellites.

Under Vladimir Putin¡¯s presidency, the GLONASS project was made a priority and received a substantial increase in funding. By October 2011, the entire constellation of 24 satellites was restored, giving full coverage in far north or south whère Russia needs GLONASS most. In terms of positional accuracy, GPS is slightly better than GLONASS overall. Still, due to the different positioning of the GLONASS satellites, GLONASS has less accuracy at lower latitudes. ºí¶óµð¹Ì¸£ Ǫƾ ´ëÅë·É ½ÃÀý, ±Û·Î³ª½º ÇÁ·ÎÁ§Æ®°¡ ¿ì¼±½ÃµÇ¾ú°í »ó´çÇÑ ÀÚ±Ý Áö¿øÀ» ¹Þ¾Ò´Ù. 2011³â 10¿ù±îÁö 24°³ À§¼º Àüü°¡ º¹¿øµÇ¾ú°í, ·¯½Ã¾Æ°¡ ±Û·Î³ª½º¸¦ °¡Àå ÇÊ¿ä·Î ÇÏ´Â °íÀ§µµ ºÏÂÊ Áö´ë³ª ³²ÂÊ¿¡¼ ¿ÏÀüÇÑ Ä¿¹ö¸®Áö¸¦ Á¦°øÇÏ¿´´Ù.

So far, the cause of the problem is a mystery. It started around 9 p.m. GMT (5 p.m. Eastern Time) on Tuesday, when most of the 24 satellites that make up the Glonass constellation began broadcasting erroneous data about their locations. The ability of satellite positioning receivers to provide an accurate fix is tied to the accuracy of the signal fròm space, so the problem immediately affected users.
